United Kingdom
–
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, the United Kingdom includes the island of Great Britain, Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state—the Republic of Ireland. The Irish Sea lies between Great Britain and Ireland, with an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants, together, this makes it the fourth-most densely populated country in the European Union. The United Kingdom is a monarchy with a parliamentary system of governance. The monarch is Queen Elizabeth II, who has reigned since 6 February 1952, other major urban areas in the United Kingdom include the regions of Birmingham, Leeds, Glasgow, Liverpool and Manchester. The United Kingdom consists of four countries—England, Scotland, Wales, the last three have devolved administrations, each with varying powers, based in their capitals, Edinburgh, Cardiff and Belfast, respectively. The relationships among the countries of the UK have changed over time, Wales was annexed by the Kingdom of England under the Laws in Wales Acts 1535 and 1542. A treaty between England and Scotland resulted in 1707 in a unified Kingdom of Great Britain, which merged in 1801 with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain, there are fourteen British Overseas Territories. These are the remnants of the British Empire which, at its height in the 1920s, British influence can be observed in the language, culture and legal systems of many of its former colonies. The United Kingdom is a country and has the worlds fifth-largest economy by nominal GDP. The UK is considered to have an economy and is categorised as very high in the Human Development Index. It was the worlds first industrialised country and the worlds foremost power during the 19th, the UK remains a great power with considerable economic, cultural, military, scientific and political influence internationally. It is a nuclear weapons state and its military expenditure ranks fourth or fifth in the world. The UK has been a permanent member of the United Nations Security Council since its first session in 1946 and it has been a leading member state of the EU and its predecessor, the European Economic Community, since 1973. However, on 23 June 2016, a referendum on the UKs membership of the EU resulted in a decision to leave. The Acts of Union 1800 united the Kingdom of Great Britain, Scotland, Wales and Northern Ireland have devolved self-government

CJON-DT
–
CJON-DT, UHF channel 21, is an English-language independent television station located in St. Johns, Newfoundland and Labrador, Canada. The station is owned by Stirling Communications International, CJONs studios are located on Logy Bay Road in St. Johns, and its transmitter is located atop the South Side Hills. The station also operates additional rebroadcast transmitters throughout the province, on Shaw Direct, the channel is available on 310 or 063, and in high definition on channel 054 or 554. There is a high definition feed offered on Rogers Cable channel 521, Eastlink TV channel 605, NTV is well known for its unusual mix of programming, particularly in the overnight hours. Although nominally an independent station, in practice it sublicenses programming via secondary affiliations with other networks, Entertainment programming is licensed from Global and Yes TV, sports programming from CTV, and news programming from Global and CTV. In 1955, Newfoundland Broadcasting Company Ltd. owner of CJON radio, applied for, Newfoundland Broadcasting was jointly owned by Geoff Stirling and Don Jamieson. The station went on the air later that year on September 6 and it was Newfoundland and Labradors first television station, and remains the provinces only privately owned station to this day. However, the CBC-owned CBYT in Corner Brook launched soon after, when it began operations, CJONs first studios and offices were located at the Prince of Wales Building in Buckmasters Circle and the transmitter on Kenmount Road. In any event, the CBC launched CBNT in 1964, in 1972, CJON-TV became one of the first television stations in Canada, if not the first, to broadcast around the clock every night. In 1977, Stirling and Jamieson unwound their partnership, with Jamieson taking the AM radio stations, in later years, many of the AM stations were eventually sold, and in several cases shut down. Stirling kept NTV and the newly launched FM station CHOZ,1983 saw NTV and OZ-FMs operations move to their present building on Logy Bay Road, with a new transmitter on the South Side Hills. CJON was the only CTV affiliate not to participate in the networks 1993 restructuring from a cooperative to a corporation, however, it retained a nominal interest until Baton Broadcasting bought controlling interest in the network in 1997. NTV became available on C-Band satellite in 1994, the original purpose of this was to ensure that viewers in rural regions were able to receive the best signal possible. It also brought the station to Labrador for the first time, however, it became a popular choice for satellite viewers across the continent, as NTVs signal was unscrambled. The station began to make reference of its new area in its promotions and branding, it adopted the globe logo it maintains today. Due to issues involving program rights, it left C-Band in 1996, NTV eventually returned to C-Band, but as an encrypted digital signal which required an expensive receiver to decode. It also became available on the Bell TV and Shaw Direct direct broadcast satellite services, due to its location, some programs that NTV airs are first shown on this station before any other North American station airs them. S. affiliate airs it. For instance, The Oprah Winfrey Show aired on NTV at 2,30 p. m. NT and may hence be indicated as a premiere, although WLS-TV in Chicago

St. John's, Newfoundland and Labrador
–
St. Johns is the capital and largest city in Newfoundland and Labrador. It is on the tip of the Avalon Peninsula on the island of Newfoundland. St. Johns covers 446.04 square kilometres and is North Americas most easterly city, excluding those of Greenland. Its name has been attributed to the Nativity of John the Baptist, existing on maps as early as 1519, it is considered by some to be the oldest English-founded city in North America. It was officially incorporated as a city in 1888, the city has a rich history, having played a role in the Seven Years War, the French and Indian War, the American Revolutionary War, and the War of 1812. Italian inventor, Guglielmo Marconi received the first transatlantic wireless signal in St. Johns and its history and culture have made it one of the worlds top ocean-side tourist destinations. St. Johns is one of North Americas oldest settlements, with setting up seasonal camps in the early 16th century. Sebastian Cabot declares in a handwritten Latin text in his original 1545 map, that St. However, the earliest record of the location appears as São João on a Portuguese map by Pedro Reinel in 1519. When John Rut visited St. Johns in 1527 he found Norman, Breton, on 3 August 1527, Rut wrote a letter to King Henry on the findings of his voyage to North America, this was the first known letter sent from North America. St. Jehan is shown on Nicholas Desliens world map of 1541 and it was during this time that Water Street was first developed, making it the oldest street in North America. On 5 August 1583, an English Sea Dog, Sir Humphrey Gilbert claimed the area as Englands first overseas colony under Royal Charter of Queen Elizabeth I. There was no permanent population, however, and Gilbert was lost at sea during his return voyage, the Newfoundland National War Memorial is on the waterfront in St. Johns, at the purported site of Gilberts landing and proclamation. By 1620, the fishermen of Englands West Country controlled most of Newfoundlands east coast, in 1627, William Payne, called St. Johns the principal prime and chief lot in all the whole country. Sometime after 1630, the town of St. Johns was established as a permanent community, before this they were expressly forbidden by the British government, at the urging of the West Country fishing industry, from establishing permanent settlements along the English controlled coast. The population grew slowly in the 17th century, St. Johns was Newfoundlands largest settlement when English naval officers began to take censuses around 1675, the population grew in the summers with the arrival of migratory fishermen. In 1680, fishing ships set up fishing rooms at St. Johns, the towns first significant defenses were likely erected due to commercial interests, following the temporary seizure of St. Johns by the Dutch admiral Michiel de Ruyter in June 1665. The inhabitants fended off a second Dutch attack in 1673, when it was defended by Christopher Martin, Martin landed six cannons from his vessel, the Elias Andrews, and constructed an earthen breastwork and battery near Chain Rock commanding the Narrows leading into the harbour. With only 23 men, the valiant Martin beat off an attack by three Dutch warships, when 1500 English reinforcements arrived in late 1697, they found rubble where the town and fortifications had stood

San Francisco Bay Area
–
The San Francisco Bay Area is a populous region surrounding the San Francisco and San Pablo estuaries in Northern California. The region encompasses the cities and metropolitan areas of San Jose, San Francisco. The Bay Areas nine counties are Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. The combined statistical area of the region is the second-largest in California, the fifth-largest in the United States, the Bay Area has the second-most Fortune 500 Companies in the United States, and is known for its natural beauty, liberal politics, entrepreneurship, and diversity. The eastern side of the bay, consisting of Alameda and Contra Costa counties, is known locally as the East Bay, the inner East Bay is more densely populated, with generally older buildings, and a more ethnically diverse population. The word Lamorinda was coined by combining the names of the cities it includes, Lafayette, Moraga, walnut Creek is situated east of Lamorinda and north of the San Ramon Valley and, together with Concord, Martinez, and Pleasant Hill comprises Central Contra Costa County. The cities of Antioch, Pittsburg, Brentwood, Oakley and the areas surrounding them comprise East Contra Costa County. The Tri-Valley consists of the Amador, the Livermore, and the San Ramon Valleys, dublin and Pleasanton comprise the Amador Valley, Livermore lies in the Livermore Valley, and the San Ramon Valley consists of Alamo, Danville, Diablo and its namesake, San Ramon. The outer East Bay is connected to the inner East Bay by BART, Interstate 580 to the south, and State Routes State Route 4 to the north, the outer East Bays infrastructure was mostly built up after World War II. This area remains largely white demographically, although the Hispanic and Filipino populations have grown significantly over the past 2–3 decades, the region north of the Golden Gate Bridge is known locally as the North Bay. This area encompasses Marin County, Sonoma County, Napa County, the city of Fairfield, being part of Solano County, is often considered the easternmost city of the North Bay. With few exceptions, this region is affluent, Marin County is ranked as the wealthiest in the state. The North Bay is relatively rural compared to the remainder of the Bay Area, with areas of undeveloped open space, farmland. Santa Rosa in Sonoma County is the North Bays largest city, with a population of 167,815 and a Metropolitan Statistical Area population of 466,891, making it the fifth-largest city in the Bay Area. The North Bay is the section of the Bay Area that is not currently served by a commuter rail service. The area from San Francisco to the Silicon Valley, geographically part of the San Francisco Peninsula, is known locally as The Peninsula, many of these families are of foreign background and have significantly contributed to the diversity of the area. Whereas the term peninsula technically refers to the entire geographical San Franciscan Peninsula, in local terms, San Francisco is surrounded by water on three sides, the north, east, and west. The city squeezes roughly 870,000 people in under 47 square miles, on any given day, there can be as many as 1 million people in the city because of the commuting population and tourism

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

San Jose, California
–
San Jose, officially the City of San José, is the economic, cultural, and political center of Silicon Valley and the largest city in Northern California. With an estimated 2015 population of 1,026,908, it is the third most populous city in California and the tenth most populous in United States. Located in the center of the Santa Clara Valley, on the shore of San Francisco Bay. San Jose is the county seat of Santa Clara County, the most affluent county in California. San Jose is the largest city in both the San Francisco Bay Area and the San Jose-San Francisco-Oakland Combined Statistical Area, which contain 7.7 million and 8.7 million people respectively. Before the arrival of the Spanish, the area around San Jose was inhabited by the Ohlone people, San Jose was founded on November 29,1777, as the Pueblo of San José de Guadalupe, the first civilian town founded in Spanish Alta California. When California gained statehood in 1850, San Jose became the states first capital, following World War II, San Jose experienced an economic boom, with a rapid population growth and aggressive annexation of nearby cities and communities carried out in the 1950s and 60s. The rapid growth of the high-technology and electronics industries further accelerated the transition from a center to an urbanized metropolitan area. Results of the 1990 U. S. Census indicated that San Jose had officially surpassed San Francisco as the most populous city in Northern California, by the 1990s, San Jose and the rest of Silicon Valley had become the global center for the high tech and internet industries. San Jose is considered to be a city, notable for its affluence. San Joses location within the high tech industry, as a cultural, political. San Jose is one of the wealthiest major cities in the United States and the world, and has the third highest GDP per capita in the world, according to the Brookings Institute. Major global tech companies including Cisco Systems, eBay, Adobe Systems, PayPal, Brocade, Samsung, Acer, Prior to European settlement, the area was inhabited by several groups of Ohlone Native Americans. The first lasting European presence began with a series of Franciscan missions established from 1769 by Junípero Serra, San Jose came under Mexican rule in 1821 after Mexico broke with the Spanish crown. It then became part of the United States, after it capitulated in 1846, on March 27,1850, San Jose became the second incorporated city in the state, with Josiah Belden its first mayor. San Jose was Californias first state capital, and hosted the first, today the Circle of Palms Plaza in downtown is the historical marker for the first state capital. The city was a station on the Butterfield Overland Mail route, in the period 1900 through 1910, San Jose served as a center for pioneering invention, innovation, and impact in both lighter-than-air and heavier-than-air flight. These activities were led principally by John Montgomery and his peers, the City of San Jose has established Montgomery Park, a Monument at San Felipe and Yerba Buena Roads, and John J. Montgomery Elementary School in his honor

Digital terrestrial television
–
Digital terrestrial television is a technological evolution of broadcast television and an advancement over analog television. A terrestrial implementation of digital television uses a aerial to broadcast to a conventional television antenna instead of a satellite dish or cable television connection. The amount of data that can be transmitted is directly affected by channel capacity, the modulation method in DVB-T is COFDM with either 64 or 16-state Quadrature Amplitude Modulation. In general, a 64QAM channel is capable of transmitting a bit rate. 16 and 64QAM constellations can be combined in a single multiplex, the DVB-T standard is not used for terrestrial digital television in North America. Instead, the ATSC standard calls for 8VSB modulation, which has similar characteristics to the vestigial sideband modulation used for analog television. This provides considerably more immunity to interference, but is not immune — as DVB-T is — to multipath distortion, both systems use the MPEG transport stream and H. 262/MPEG-2 Part 2 video codec specified in MPEG-2, they differ significantly in how related services are encoded. DTTV is received either via a digital set-top box, TV gateway or integrated tuner included with television sets, some set-top-boxes and TV gateways include digital video recorder functionality. This is quite common in the UK, see external links, indoor aerials are even more likely to be affected by these issues and possibly need replacing. Main articles, List of digital television deployments by country, Digital television transition Afghanistan started digital transmissions in MPEG-4 on Sunday,31 August 2014, Afghanistan adopted DVB-T2 system for digital television. India adopted DVB-T system for television in July 1999. The first DVB-T transmission was started on 26 January 2003 in the four metropolitan cities by Doordarshan. Currently the terrestrial transmission is available in digital and analog formats. 4 high power DVB-T transmitters were set up in the top 4 cities, an additional 190 high power, and 400 low power DVB-T2 transmitters have been approved for Tier I, II and III cities of the country by 2017. The Indian telecom regulator, TRAI, had recommended the I&B to allow private broadcast companies to use the DTT technology, so far, the Indian I&B ministry only permits private broadcast companies to use satellite, cable and IPTV based systems. Israel started digital transmissions in MPEG-4 on Sunday,2 August 2009, Israel was the first nation in the Middle East and the first non-European nation to shut down its analogue TV distribution system. The new service which is operated by the Second Authority for Radio, according to government decisions, the system will expand to include two additional multiplexes that will carry new channels and HD versions of the existing channels. In this matter nothing has been decided upon until the end on 2012, on 20 March 2013 it was announced that Thomson Broadcast had won a major contract with The Second Authority for Television and Radio for the extension of its nationwide DVB-T/DVB-T2 network

Very high frequency
–
Very high frequency is the ITU designation for the range of radio frequency electromagnetic waves from 30 MHz to 300 MHz, with corresponding wavelengths of ten to one meters. Frequencies immediately below VHF are denoted high frequency, and the higher frequencies are known as ultra high frequency. Air traffic control communications and air navigation systems work at distances of 100 kilometres or more to aircraft at cruising altitude, some older DVB-T receivers included channels E2 to E4 but newer ones only go down to channel E5. VHF propagation characteristics are suited for terrestrial communication, with a range generally somewhat farther than line-of-sight from the transmitter. VHF waves are restricted to the radio horizon less than 100 miles. VHF is less affected by noise and interference from electrical equipment than lower frequencies. Unlike high frequencies, the ionosphere does not usually reflect VHF waves, the distance to the radio horizon is slightly extended over the geometric line of sight to the horizon, as radio waves are weakly bent back toward the Earth by the atmosphere. These approximations are only valid for antennas at heights that are compared to the radius of the Earth. They may not necessarily be accurate in mountainous areas, since the landscape may not be transparent enough for radio waves, in engineered communications systems, more complex calculations are required to assess the probable coverage area of a proposed transmitter station. The accuracy of calculations for digital TV signals is being debated. Portable radios usually use whips or rubber ducky antennas, while base stations usually use larger fiberglass whips or collinear arrays of vertical dipoles, for directional antennas, the Yagi antenna is the most widely used as a high gain or beam antenna. For television reception, the Yagi is used, as well as the log periodic antenna due to its wider bandwidth, helical and turnstile antennas are used for satellite communication since they employ circular polarization. For even higher gain, multiple Yagis or helicals can be mounted together to make array antennas, vertical collinear arrays of dipoles can be used to make high gain omnidirectional antennas, in which more of the antennas power is radiated in horizontal directions. Television and FM broadcasting stations use arrays of specialized dipole antennas such as batwing antennas. Certain subparts of the VHF band have the same use around the world, some national uses are detailed below. 108–118 MHz, Air navigation beacons VOR and Instrument Landing System localiser, 118–137 MHz, Airband for air traffic control, AM,121.5 MHz is emergency frequency 144–146 MHz, Amateur radio. Other capital cities and regional areas used a combination of these, the initial commercial services in Hobart and Darwin were respectively allocated channels 6 and 8 rather than 7 or 9. By the early 1960s it became apparent that the 10 VHF channels were insufficient to support the growth of television services and this was rectified by the addition of three additional frequencies—channels 0, 5A and 11

Program and System Information Protocol
–
PSIP defines virtual channels and content ratings, as well as electronic program guides with titles and descriptions to be decoded and displayed by the ATSC tuner. PSIP can also send, the exact time referenced to UTC and GPS time, the short name, a maximum of seven characters can be used in a short name. PSIP is defined in ATSC standard A/65, the most recent revision of which is A/65,2013, a/69 is a recommended practice for implementing PSIP in a television station. PSIP also supersedes the A/55 and A/56 protocol methods of delivering program guide information, PSIP information may be passed through the airchain using proprietary protocols or through use of the XML-based Programming Metadata Communication Protocol facility metadata scheme.

Ultra high frequency
–
Ultra high frequency is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre. Radio waves with frequencies above the UHF band fall into the SHF or microwave frequency range, lower frequency signals fall into the VHF or lower bands. UHF radio waves propagate mainly by line of sight, they are blocked by hills, the IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz. Two other IEEE radar bands overlap the ITU UHF band, the L band between 1 and 2 GHz and the S band between 2 and 4 GHz. Radio waves in the UHF band travel almost entirely by propagation and ground reflection, there is very little reflection from the ionosphere. They are blocked by hills and cannot travel far beyond the horizon, atmospheric moisture reduces, or attenuates, the strength of UHF signals over long distances, and the attenuation increases with frequency. UHF TV signals are generally more degraded by moisture than lower bands, occasionally when conditions are right, UHF radio waves can travel long distances by tropospheric ducting as the atmosphere warms and cools throughout the day. The length of an antenna is related to the length of the radio waves used, the UHF antenna is stubby and short, at UHF frequencies a quarter-wave monopole, the most common omnidirectional antenna is between 2.5 and 25 cm long for example. UHF is widely used in telephones, cell phones, walkie-talkies and other two-way radio systems from short range up to the visual horizon. Their transmissions do not travel far, allowing frequency reuse, public safety, business communications and personal radio services such as GMRS, PMR446, and UHF CB are often found on UHF frequencies as well as IEEE802.11 wireless LANs. The widely adapted GSM and UMTS cellular networks use UHF cellular frequencies, radio repeaters are used to retransmit UHF signals when a distance greater than the line of sight is required. Omnidirectional UHF antennas used on mobile devices are usually short whips, higher gain omnidirectional UHF antennas can be made of collinear arrays of dipoles and are used for mobile base stations and cellular base station antennas. The short wavelengths also allow high gain antennas to be conveniently small, high gain antennas for point-to-point communication links and UHF television reception are usually Yagi, log periodic, corner reflectors, or reflective array antennas. At the top end of the band slot antennas and parabolic dishes become practical, for television broadcasting specialized vertical radiators that are mostly modifications of the slot antenna or helical antenna are used, the slotted cylinder, zig-zag, and panel antennas. UHF television broadcasting fulfilled the demand for additional over-the-air television channels in urban areas, today, much of the bandwidth has been reallocated to land mobile, trunked radio and mobile telephone use. UHF channels are used for digital television. UHF spectrum is used worldwide for mobile radio systems for commercial, industrial, public safety. Many personal radio services use frequencies allocated in the UHF band, major telecommunications providers have deployed voice and data cellular networks in UHF/VHF range

NBC
–
The National Broadcasting Company is an American commercial broadcast television network that is the flagship property of NBCUniversal, a subsidiary of Comcast. The network is part of the Big Three television networks, founded in 1926 by the Radio Corporation of America, NBC is the oldest major broadcast network in the United States. Following the acquisition by GE, Bob Wright served as executive officer of NBC, remaining in that position until his retirement in 2007. In 2003, French media company Vivendi merged its entertainment assets with GE, Comcast purchased a controlling interest in the company in 2011, and acquired General Electrics remaining stake in 2013. Following the Comcast merger, Zucker left NBC Universal and was replaced as CEO by Comcast executive Steve Burke, during a period of early broadcast business consolidation, radio manufacturer Radio Corporation of America acquired New York City radio station WEAF from American Telephone & Telegraph. Westinghouse, a shareholder in RCA, had an outlet in Newark, New Jersey pioneer station WJZ. This station was transferred from Westinghouse to RCA in 1923, WEAF acted as a laboratory for AT&Ts manufacturing and supply outlet Western Electric, whose products included transmitters and antennas. The Bell System, AT&Ts telephone utility, was developing technologies to transmit voice- and music-grade audio over short and long distances, the 1922 creation of WEAF offered a research-and-development center for those activities. WEAF maintained a schedule of radio programs, including some of the first commercially sponsored programs. In an early example of chain or networking broadcasting, the station linked with Outlet Company-owned WJAR in Providence, Rhode Island, AT&T refused outside companies access to its high-quality phone lines. The early effort fared poorly, since the telegraph lines were susceptible to atmospheric. In 1925, AT&T decided that WEAF and its network were incompatible with the companys primary goal of providing a telephone service. AT&T offered to sell the station to RCA in a deal that included the right to lease AT&Ts phone lines for network transmission, the divisions ownership was split among RCA, its founding corporate parent General Electric and Westinghouse. NBC officially started broadcasting on November 15,1926, WEAF and WJZ, the flagships of the two earlier networks, were operated side-by-side for about a year as part of the new NBC. On April 5,1927, NBC expanded to the West Coast with the launch of the NBC Orange Network and this was followed by the debut of the NBC Gold Network, also known as the Pacific Gold Network, on October 18,1931. The Orange Network carried Red Network programming, and the Gold Network carried programming from the Blue Network, initially, the Orange Network recreated Eastern Red Network programming for West Coast stations at KPO in San Francisco. The Orange Network name was removed from use in 1936, at the same time, the Gold Network became part of the Blue Network. In the 1930s, NBC also developed a network for shortwave radio stations, in 1927, NBC moved its operations to 711 Fifth Avenue in Manhattan, occupying the upper floors of a building designed by architect Floyd Brown

Owned-and-operated station
–
In the broadcasting industry, an owned-and-operated station usually refers to a television or radio station that is owned by the network with which it is associated. This distinguishes such a station from an affiliate, which is independently owned, the concept of an O&O is clearly defined in the United States and Canada, where network-owned stations had historically been the exception rather than the rule. In the broadcasting industry, the term owned-and-operated station refers exclusively to stations that are owned by television, on the other hand, the term affiliate only applies to stations that are not owned by networks, but instead are contracted to air programming from one of the major networks. The term station correctly applies to the ownership of the station, for example, a station that is owned and operated by the American Broadcasting Company is referred to as an ABC station or an ABC O&O, but normally should not be referred to as an affiliate. Likewise, a station not owned by ABC but contracted to air the networks programming is referred to as an ABC affiliate, that is. A correct formal phrasing could be, ABC affiliate WFAA is a Gannett station, some stations that are owned by companies that operate a network, but air another networks programming are referred to as an affiliate of the network that they carry. For example, WBFS-TV in Miami is owned by the CBS networks parent company CBS Corporation, prior to the September 2006 shutdown of the CBS-owned UPN television network, WBFS aired that networks programming, therefore, WBFS was a UPN O&O. The stations carrying The WB Television Network were another exception, the controlling shares in the network were held by Time Warner, with minority interests from the Tribune Company and, for a portion of networks existence, the now-defunct ACME Communications. While Tribune-owned stations such as WGN-TV in Chicago, WPIX in New York City and KTLA in Los Angeles aired programming from The WB, a similar exception existed when UPN launched in January 1995 by co-owners Chris-Craft and Viacom. Each of the owned a number of stations that aired the network. However, the stations were not considered O&Os under the initial standard definition. This ambiguity ended with Viacoms buyout of Chris-Crafts share of the network in 2000, the stations were referred to informally as UPN O&Os. Following the shutdowns of UPN and The WB, CBS Corporation, Entertainment became co-owners of the new CW Television Network, which largely merged the programming from both networks onto the scheduling model used by The WB. The network launched in September 2006 on 11 UPN stations owned by CBS Corporation, certain UPN and WB affiliates in markets where Tribune and CBS both owned stations carrying those networks either picked up a MyNetworkTV affiliation or became independent stations. The standard definition of an O&O again does not apply to The CW, in Australia, Seven Network, Nine Network and Network Ten each own and operate stations in the five largest metropolitan areas. These television markets together account for two thirds of the countrys population, in addition, Seven also owns and operates its local station in regional Queensland, and Nine owns and operates its station in Darwin. Nine also owns and operates NBN Television, based in Newcastle, the two national public broadcasters, the Australian Broadcasting Corporation and Special Broadcasting Service, own and operate all of their local stations. In Japan, commercial terrestrial television is focused on five organizations, the four largest of these – Nippon TV, Tokyo Broadcasting System, Fuji Television, and TV Asahi – each own and operate stations in the Tokyo, Keihanshin, Chukyo and Fukuoka metropolitan areas

Cozi TV
–
Cozi TV is an American digital multicast television network that is owned by the NBCUniversal Owned Television Stations division of NBCUniversal. The network airs classic television series from the 1950s to the 1990s, in June 2010, NBC Local Media appointed former WNBC general manager Tom OBrien in the newly created position of executive vice president of Nonstop Network. In October, WNBC sister stations WCAU and WRC-TV respectively launched their own versions of the Nonstop channel in the Philadelphia and Washington, chicagos WMAQ-TV launched its own local version in November 2010. Each stations Nonstop subchannel carried eight hours of locally produced programming, along with programming from affiliated production company LXTV. An NBC executive indicated that the independently-formatted Nonstop channels were performing well, by July 2012, it was announced that NBC was considering using a different name for the national network, with Bob TV among the names being put under consideration. NBC soft launched Cozi TV on its stations as well as some charter affiliates on December 20,2012. Cozis Sunday schedule is preempted in whole to allow FETV to carry religious programming, NBCUniversal broadcasts Cozi TV in most markets served by a station owned by the NBCUniversal Owned Television Stations group, either on subchannels of NBC or Telemundo stations. The network is available on the digital subchannels of other television stations. The network soft-launched on NBC and Telemundo owned-and-operated stations in most markets. S. By July 2013, the networks reach had expanded to 42% of the U. S. through affiliation deals with WMFP in Boston, KUBE-TV in Houston and the E. W. Scripps Companys KSHB-TV in Kansas City. Croix and New Orleans, the network announced a deal with OTA Broadcasting, LLC to affiliate with KFFV in Seattle. Both deals expanded the reach to 60% of the U. S. As of December 13,2015, the Minneapolis–St, paul market area was the largest without a CoziTV affiliate

Telemundo is an American Spanish-language terrestrial television network owned by Comcast through the NBCUniversal division NBCUniversal Telemundo Enterprises. It is the second largest provider of Spanish content nationwide behind American competitor Univision, Telemundo is headquartered in the Miami suburb of Hialeah, Florida, and has 1,900 employees worldwide. The majority of Telemundos programs are filmed at a studio facility in Miami. The average hourly primetime drama costs $70K to produce. S, Ramos wanted to maintain a consistent branding for his media properties based around the mundo theme, and chose to brand his new television property as Telemundo. Rivero produced the first comedy/variety series for WKAQ-TV, La Taberna India, and La Farándula Corona on YouTube, during the 1970s and 1980s, WKAQ-TV, then branded as Telemundo Canal 2, had become a major producer of telenovelas. The station was known for its fingers logo – a bold number 2 with the silhouette of two upright fingers inside the number – and referred to itself as El canal de los dedos. On April 14,1983, Ramos sold WKAQ-TV to John Blair & Co, in 1984, the owners of WNJU in Linden, New Jersey and KSTS in San Jose, California formed NetSpan, the second Spanish-language television network in the continental United States. These stations joined KVEA in Los Angeles, run by its manager and part-owner Joe Wallach. In late 1986, Reliance also purchased WNJU, in 1987, Reliance Capital Group executives Saul Steinberg and Henry Silverman merged all these stations into the Telemundo Group. The new corporation quickly went public, and in 1987, Reliance decided to rebrand NetSpan as Telemundo, later that year, it purchased additional stations in San Francisco, Houston and San Antonio. Between 1988 and 1993, Telemundo acquired or affiliated with stations in Texas, New Mexico, Arizona and Washington. In May 1992, Telemundo underwent another management change, appointing former Univision president Joaquin Blaya – who resigned from that network after discovering in an FCC filing for A. The following year in 1993, Telemundo underwent a rebranding, introducing the signature framed T letter logo. The network also began to produce its own telenovelas, the first of which to premiere were Angélica, mi vida, Marielena, Guadalupe, Señora Tentación. International distributors soon approached the network for the rights to air these programs on television networks in other countries. In 1995, under the direction of executive president of programming Harry Abraham Castillo. Eastern time slot on certain weeknights to help bolster its late newscasts, after the sale received FCC approval on July 31,1998, Sony and Liberty formed a holding company that was operated as a 50/50 joint venture between both companies, Telemundo Communications Group. Among them were Angeles, a remake of Charlies Angels, Un Angel en la Casa, solo en America, a remake of One Day at a Time

KSTS, virtual channel 48, is a Telemundo owned-and-operated television station serving the San Francisco Bay Area that is licensed to San Jose, California, United States. The station is owned by the NBCUniversal Owned Television Stations subsidiary of NBCUniversal, the two stations share studios and offices located on North 1st Street in San Jose. KSTSs transmitter is located atop Mount Allison, the station first signed on the air on May 31,1981 as an independent station. It was owned by National Group Television, which was headed by N. J. Douglas, the station initially offered programming weekdays from 5 a. m. to 3 p. m. from the Financial News Network. The station branded under the slogan Your Computer Connection, KSTS was also the only station to broadcast the introduction of Apples Macintosh personal computer at the companys 1984 Annual Shareholders Meeting. Beginning in the fall of 1981, KSTS carried the television service Star TV, featuring recent movies. By 1983, they were carrying subscription TV after 12 noon on weekends, by 1983, the off network shows were dropped for more brokered programming. That year, the station ran various brokered programming weekends from 5 a. m. to noon, Financial News remained weekdays till 3 p. m. NightMusic premiered in August 1984, a three-hour weekly live show that featured music videos and comedy. Hosted by John Ward with co-host Brian Leonard NightMusic aired from 9PM to 12M every Saturday for a year, chris Isaak was a frequent guest and Translator once served as the house band. Jay Peterson was a staff announcer, in 1984, Star TV began winding down operations due to the fact cable penetration eliminated the need for Subscription TV over the air. By 1986, KSTS was running Spanish programming for half of its broadcast day on weekdays. Later that year the Financial News Network programming ended and the became the entire broadcast day. NetSpan was relaunched as Telemundo in mid-1987, by then, the station was running the networks programming about 16 hours a day. Telemundo bought the station later that year, at which time KSTS began carrying Telemundo programming full-time. Initially, KSTS was targeted at the San Jose/Silicon Valley region, the station moved into all-digital broadcast center housed alongside KNTV in 2004. The stations digital channel is multiplexed, KSTS also has a Mobile DTV feed of subchannel 48.1, KSTS shut down its analog signal, over UHF channel 48, on June 12,2009, as part of the federally mandated transition from analog to digital television. The stations digital signal remained on its pre-transition UHF channel 49, KSTS presently broadcasts five hours of locally produced newscasts each week. In 1988, KSTS launched its news department with the debut of a half-hour 6pm newscast, the program proved successful, which resulted in the station later adding a half-hour 11pm newscast

NBCUniversal is an American multinational media conglomerate. It has a significant presence in broadcasting through a portfolio of domestic and international properties, including terrestrial, via the Universal Parks & Resorts division, the company is also the third-largest operator of amusement parks in the world. NBC Universal was formed on May 12,2004 by the merger of General Electrics National Broadcasting Company with Vivendis Vivendi Universal Entertainment, as of March 19,2013, it is wholly owned by Comcast who bought GEs ownership stake. NBC and Universal Television had a long-standing partnership dating back to 1950 and this partnership continued throughout a number of name changes and changes of ownership. NBC Universal Television has its roots in a series of expansions undertaken by NBC. In the late 1980s, NBC began pursuing a strategy of diversification, NBC also had partial ownership of several regional sports channels and other cable channels such as American Movie Classics and Court TV. In 1995, NBC began operating NBC Desktop Video, a news service that delivered live video to personal computers. The following year, NBC announced an agreement with Microsoft to create an all-news cable television channel, a separate joint venture with Microsoft included establishing a news website, MSNBC. com. In 1998, NBC partnered with Dow Jones & Co, the two companies combined their financial news channels outside the US. The new networks included NBC Europe, CNBC Europe, NBC Asia, CNBC Asia, NBC Africa, in 1999, NBC took a 32% stake in the Paxson group, operator of PAX TV. Five years later, NBC decided to sell its interest in PAX TV and end its relationship with PAX owner, in 2001, NBC acquired the US Spanish-language broadcaster Telemundo, which included the bilingual Mun2 Television. That same year NBC acquired the cable channel Bravo, the sale and resulting merger formed NBC Universal. The new company was 80% owned by GE, and 20% owned by Vivendi, Universal Music Group was not included in the deal and is not part of NBC Universal. On August 2,2004, the divisions of NBC. NBC Studios series bought into the company include the NBC dramas Las Vegas, Crossing Jordan, Universal Network Television bought the Law & Order franchise and The District—in fact, Universal Network Television had co-produced American Dreams with NBC before the merger. Entertainment shows produced by the new group include The Tonight Show with Jay Leno, Late Night with Jimmy Fallon, Last Call with Carson Daly, and Saturday Night Live. The formation of NBC Universal saw the establishment of NBC Universal Cable, which oversees the distribution, marketing, NBC Universal Cable also manages the companys investments in The Weather Channel and TiVo. The cable division also used to operate NBC Weather Plus until 2008 and it also owned a 50% stake in Canal+ and also owned a 15% stake in A+E Networks until 2012

NBC Sports Bay Area is an American regional sports network that is owned as a joint venture between NBCUniversal and the San Francisco Giants, and operates as an affiliate of NBC Sports Group. Headquartered in San Francisco, the channel broadcasts coverage of professional sports events throughout the San Francisco Bay Area. NBCS Bay Areas sister channel is NBC Sports California, the president of the network is Ted Griggs. The two networks merged in July 1991 into SportsChannel Pacific, on April 30,2007, Comcast purchased a 60% interest in FSN Bay Area, along with a 50% stake in FSN New England, from Rainbow Media for $570 million. Then on December 10, the San Francisco Giants acquired a 30% stake in FSN Bay Area, shortly after the rebranding, in April 2008, Fox agreed to sell its interest in CSN Bay Area to Comcast. The revamp would also include interviews in addition to providing scores and highlights. The channel also broadcasts college sports sanctioned by the West Coast Conference, select high school sports events are also occasionally broadcast on the network. Until 2004, the network also broadcast games involving the NBAs Sacramento Kings, following the expiration of their contracts with the then-FSN Bay Area, the owners of the Kings partnered with Comcast to create CSN Bay Areas sister channel, Comcast SportsNet West. This arrangement was formed to secure coverage for its lineup of collegiate sports events. The channel also aired simulcasts of radio such as The Dan Patrick Show until those programs were inherited by NBC Sports Network

NBC Sports California
–
NBC Sports California is an American regional sports network that is owned by the NBC Sports Group unit of NBCUniversal, and operates as an affiliate of NBC Sports Regional Networks. The channel broadcasts coverage of professional and college sports events throughout Northern California, as well as original sports-related news, discussion. NBC Sports California is available on cable and fiber optic television providers throughout northern California, the network maintains main studios and offices headquartered with sister network NBC Sports Bay Area in San Jose, California. In the summer of 2003, Comcast acquired the television rights to broadcast regular season. Previously, the game broadcasts were only available either via pay-per-view sports packages. Although the network focused on the Northern California region, it began expanding its coverage to serve as a complement to Comcast SportsNet Bay Area. The San Jose Sharks followed the As from CSN Bay Area for the 2009–10 NHL season, with the relaunch, Comcast SportsNet Bay Area and California merged editorial coverage on their respective regional websites. Many cable providers in the San Francisco Bay Area that previously carried CSN California via digital cable have since moved to the network to basic cable tiers. Negotiations went on for months, leading Dish to file a request with the Federal Communications Commission to enter into arbitration hearings to formalize a deal, Dish Network lost its case and dropped Comcast SportsNet California from its lineup on November 24,2010. On February 3,2011, Dish Network restored CSN California after the satellite reached a agreement to carry the channel without any legal arbitration. The network produces its pre-game and post-game shows for Oakland Athletics either on-site during home games, the station also airs Shark Byte, a magazine program focusing on the San Jose Sharks that originated on Comcast SportsNet Bay Area. The network also carries programming related to the NFLs Oakland Raiders, select high school sports events are also occasionally broadcast on the network, including weekly high school football games on Friday nights during the fall. m. Comcast SportsNet California previously also broadcast the Raiders Report, a show featuring news. In September 2009, the program was replaced by a live show airing immediately after network telecasts of Raiders games. The feed broadcasts all Sacramento Kings home game telecasts, as well as all home and some games involving the San Jose Sharks in HD. In 2010, CSN California began broadcasting all Athletics games in high definition

American Broadcasting Company
–
The network is headquartered on Columbus Avenue and West 66th Street in Manhattan, New York City. There are additional offices and production facilities elsewhere in New York City, as well as in Los Angeles and Burbank. Since 2007, when ABC Radio was sold to Citadel Broadcasting, ABC originally launched on October 12,1943, as a radio network, separated from and serving as the successor to the NBC Blue Network, which had been purchased by Edward J. Noble. It extended its operations to television in 1948, following in the footsteps of established broadcast networks CBS, in the mid-1950s, ABC merged with United Paramount Theatres, a chain of movie theaters that formerly operated as a subsidiary of Paramount Pictures. Leonard Goldenson, who had been the head of UPT, made the new television network profitable by helping develop, in 1996, most of Capital Cities/ABCs assets were purchased by The Walt Disney Company. The television network has eight owned-and-operated and over 232 affiliated television stations throughout the United States, most Canadians have access to at least one U. S. ABC News provides news and features content for radio stations owned by Citadel Broadcasting. In the 1930s, radio in the United States was dominated by three companies, the Columbia Broadcasting System, the Mutual Broadcasting System and the National Broadcasting Company. The last was owned by electronics manufacturer Radio Corporation of America, in 1938, the FCC began a series of investigations into the practices of radio networks and published its report on the broadcasting of network radio programs in 1940. The report recommended that RCA give up control of either NBC Red or NBC Blue, at that time, the NBC Red Network was the principal radio network in the United States and, according to the FCC, RCA was using NBC Blue to eliminate any hint of competition. Once Mutuals appeals against the FCC were rejected, RCA decided to sell NBC Blue in 1941, the newly separated NBC Red and NBC Blue divided their respective corporate assets. Investment firm Dillon, Read & Co. offered $7.5 million to purchase the network, Edward John Noble, the owner of Life Savers candy, drugstore chain Rexall and New York City radio station WMCA, purchased the network for $8 million. Due to FCC ownership rules, the transaction, which was to include the purchase of three RCA stations by Noble, would require him to resell his station with the FCCs approval, the Commission authorized the transaction on October 12,1943. Soon afterward, the Blue Network was purchased by the new company Noble founded, Noble subsequently acquired the rights to the American Broadcasting Company name from George B. Meanwhile, in August 1944, the West Coast division of the Blue Network, both stations were then managed by Don Searle, the vice-president of the Blue Networks West Coast division. The ABC Radio Network created its audience slowly, the network also became known for such suspenseful dramas as Sherlock Holmes, Gang Busters and Counterspy, as well as several mid-afternoon youth-oriented programs. S. From Nazi Germany after its conquest, to pre-record its programming, while its radio network was undergoing reconstruction, ABC found it difficult to avoid falling behind on the new medium of television. To ensure a space, in 1947, ABC submitted five applications for television station licenses, the ABC television network made its debut on April 19,1948, with WFIL-TV in Philadelphia becoming its first primary affiliate

The WB
–
The WB Television Network was an American television network that was first launched on broadcast television on January 11,1995 as a joint venture between the Warner Bros. Entertainment division of Time Warner and the Tribune Broadcasting subsidiary of the Tribune Company, on January 24,2006, CBS Corporation and Warner Bros. Entertainment announced plans to shut down the network and launch The CW later that same year, the WB Television Network shut down on September 17,2006, with select programs from both it and competitor UPN moving to The CW when it launched the following day, September 18. Time Warner re-used The WB brand for a network that launched on April 28,2008. The website could only be accessed within the United States, on November 2,1993, the Warner Bros. Only five of these stations – along with a sixth that Tribune acquired the following year – would join The WB at launch, when the network was announced, The WB planned to run a predominately network programmed schedule over time. The WB Television Network premiered on January 11,1995, with the episode of The Wayans Bros. as its first program. The classic Warner Bros. cartoon character Michigan J. Frog appeared on-air as the official mascot. Much of the branding was based around Warner Bros. locations and characters. Pictures shield logo, network promotions and imaging campaigns for The WB, the networks first programs were mostly sitcoms targeted at an ethnically black audience. Even though four of the five shows that debuted in the netlets first nine months were renewed beyond the first year – The Wayans Bros, unhappily Ever After, The Parent Hood and Sister, Sister – none of them made a significant impact. On August 17,1995, the Tribune Company acquired a 12. 5% on March 31,1997, the WB expanded its programming to Sunday nights for the 1995–96 season, but none of the new shows managed to garner much viewing interest. The WB continued to expand in the 1996–97 season, adding programming on Monday nights and this season gave The WB modest hits in the Aaron Spelling-produced family drama 7th Heaven and comedies The Steve Harvey Show and The Jamie Foxx Show. The WB first began to experience success with Buffy the Vampire Slayer and it debuted with the highest Monday night ratings in the networks history, attracting not only new teenage viewers, but new advertisers as well. The networks breakout hit and, arguably, its series was Dawsons Creek. At the start of the 1998–99 season, the network expanded its programming to Thursday nights, for the 1999–2000 season, the network concluded its primetime expansion with the addition of programming on Friday nights. During this season, The WB was the network to have gains in its total audience viewership. As the teen boom of the late 1990s began to wane, although teen-oriented fare like Popular and Roswell had premiered to strong ratings, both series saw serious ratings erosion in their sophomore seasons, leading the network to cancel them both

Effective radiated power
–
Effective radiated power, synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency power transmitted from a theoretical half-wave dipole antenna. It is differentiated from effective isotropic radiated power mainly by use of antenna gain instead of absolute gain in the calculation. The term antenna gain is assumed to be absolute unless specifically stated to be relative, the gain is then multiplied by the power actually accepted by the antenna to result in the actual ERP value. Power losses which occur prior to the antenna, e. g. in the line or from inefficiency in the generator itself are therefore not included in the calculation of ERP or EIRP. Antenna gain is closely related to directivity and often used interchangeably. However, gain is less than directivity by a factor called radiation efficiency. Whereas directivity is entirely a function of wavelength and the geometry and type of antenna, specifically, accelerating charge causes electromagnetic radiation per Maxwells equations. Therefore, antennas use a current distribution on radiating elements to generate electromagnetic energy that propagates away from the antenna and this coupling is never 100% efficient, and therefore antenna gain will always be less than directivity by this efficiency factor. The receiver would not be able to determine a difference, maximum directivity of an ideal half-wave dipole is a constant, i. e.0 dBd =2.15 dBi. Therefore, ERP is always 2.15 dB less than EIRP, the ideal dipole antenna could be further replaced by an isotropic radiator, and the receiver cannot know the difference so long as the input power is increased by 2.15 dB. Unfortunately, the distinction between dBd and dBi is often left unstated and the reader is forced to infer which was used. For example, a Yagi-Uda antenna is constructed from several dipoles arranged at intervals to create better energy focusing than a simple dipole. Since it is constructed from dipoles, often its antenna gain is expressed in dBd, obviously this ambiguity is undesirable with respect to engineering specifications. A Yagi-Uda antennas maximum directivity is 8.77 dBd =10.92 dBi and its gain necessarily must be less than this by the factor η, which must be negative in units of dB. Neither ERP nor EIRP can be calculated without knowledge of the power accepted by the antenna, let us assume a 100 Watt transmitter with losses of 6 dB prior to the antenna. ERP <22. 77dBW and EIRP <24. 92dBW, polarization has not been taken into account so far, but properly it must be. When considering the dipole radiator previously we assumed that it was aligned with the receiver. Now assume, however, that the antenna is circularly polarized

Kilowatt
–
The watt is a derived unit of power in the International System of Units defined as 1 joule per second and can be used to quantify the rate of energy transfer. Power has dimensions of M L2 T −3, when an objects velocity is held constant at one meter per second against constant opposing force of one newton the rate at which work is done is 1 watt. 1 W =1 V ⋅ A Two additional unit conversions for watt can be using the above equation. 1 W =1 V2 Ω =1 A2 ⋅ Ω Where ohm is the SI derived unit of electrical resistance, a person having a mass of 100 kilograms who climbs a 3-meter-high ladder in 5 seconds is doing work at a rate of about 600 watts. Mass times acceleration due to gravity times height divided by the time it takes to lift the object to the given height gives the rate of doing work or power. A laborer over the course of an 8-hour day can sustain an output of about 75 watts, higher power levels can be achieved for short intervals. The watt is named after the Scottish scientist James Watt for his contributions to the development of the steam engine, in 1960 the 11th General Conference on Weights and Measures adopted it for the measurement of power into the International System of Units. For additional examples of magnitude for multiples and submultiples of the watt, technologically important powers that are measured in femtowatts are typically found in reference to radio and radar receivers. For example, meaningful FM tuner performance figures for sensitivity, quieting and these input levels are often stated in dBf. This is 0.2739 microvolt across a 75-ohm load or 0.5477 microvolt across a 300-ohm load, the picowatt is equal to one trillionth of a watt. Technologically important powers that are measured in picowatts are typically used in reference to radio and radar receivers, acoustics, the nanowatt is equal to one billionth of a watt. Important powers that are measured in nanowatts are also used in reference to radio. The microwatt is equal to one millionth of a watt, compact solar cells for devices such as calculators and watches are typically measured in microwatts. The milliwatt is equal to one thousandth of a watt, a typical laser pointer outputs about five milliwatts of light power, whereas a typical hearing aid for people uses less than one milliwatt. Audio signals and other electronic signal levels are measured in dBm. The kilowatt is equal to one thousand watts and this unit is typically used to express the output power of engines and the power of electric motors, tools, machines, and heaters. It is also a unit used to express the electromagnetic power output of broadcast radio. One kilowatt is equal to 1.34 horsepower

Planning permission
–
Planning permission or developmental approval refers to the approval needed for construction or expansion in some jurisdictions. It is usually given in the form of a building permit, generally, the new construction must be inspected during construction and after completion to ensure compliance with national, regional, and local building codes. Planning is also dependent on the sites zone – for example, one cannot obtain permission to build a nightclub in an area where it is inappropriate, such as a high-density suburb. Failure to obtain a permit can result in fines, penalties, house building permits, for example, are subject to local housing statutes. The criteria for planning permission is a part of planning and construction law. Since building permits usually precede outlays for construction, employment, financing and furnishings and this type of permit is issued by a national broadcasting authority, but does not imply zoning any other permission that must be given by local government. The permit itself also does not necessarily imply permission to operate the station once constructed, in the U. S. a construction permit is valid for three years. Afterwards, the station must receive a license to operate. This is provided by a separate broadcast license, also called a license to cover by the Federal Communications Commission in the United States, further permission or registration for towers may be needed from aviation authorities. In the U. S. construction permits for commercial stations are now assigned by auction, rather than the former process of determining who would serve the community of license best

Height above average terrain
–
Height above average terrain is a measure of how high an antenna site is above the surrounding landscape. HAAT is used extensively in FM radio and television, as it is more important than effective radiated power in determining the range of broadcasts. Stations that want to increase above a certain HAAT must reduce their power accordingly, the entire radial graph could be rotated to achieve the best effect for the station. The altitude of the site, minus the average altitude of all the specified points, was the HAAT. This can create some unusual cases, particularly in mountainous regions—it is possible to have a number for HAAT. The FCC has divided the Contiguous United States into three zones for the determination of spacing between FM and TV stations using the same frequencies, FM and TV stations are assigned maximum ERP and HAAT values, depending on their assigned zones, to prevent co-channel interference. The FCC regulations for ERP and HAAT are listed under Title 47, Maximum HAAT,150 meters Maximum ERP,50 kW Minimum co-channel separation,241 km Maximum HAAT,600 meters Maximum ERP,100 kW Minimum co-channel separation,290 km. In addition, Zone I-A consists of all of California south of 40° north latitude, Puerto Rico, zones I and I-A have the most grandfathered overpowered stations, which are allowed the same extended coverage areas that they had before the zones were established. One of the most powerful of these stations is WBCT in Grand Rapids, Michigan, Zone III consists of all of Florida and the areas of Alabama, Georgia, Louisiana, Mississippi, and Texas within approximately 241.4 kilometers of the Gulf of Mexico. Zone II is all the rest of the Continental United States, Alaska and Hawaii

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Federal Communications Commission
–
The FCC works towards six goals in the areas of broadband, competition, the spectrum, the media, public safety and homeland security, and modernizing itself. The FCC was formed by the Communications Act of 1934 to replace the radio regulation functions of the Federal Radio Commission, the FCC took over wire communication regulation from the Interstate Commerce Commission. The FCCs mandated jurisdiction covers the 50 states, the District of Columbia, the FCC also provides varied degrees of cooperation, oversight, and leadership for similar communications bodies in other countries of North America. The FCC is funded entirely by regulatory fees and it has an estimated fiscal-2016 budget of US$388 million. Consistent with the objectives of the Act as well as the 1993 Government Performance and Results Act and these are, Broadband All Americans should have affordable access to robust and reliable broadband products and services. Competition Competition in the provision of services, both domestically and overseas, supports the Nations economy. The competitive framework for communications services should foster innovation and offer consumers reliable, Media The Nations media regulations must promote competition and diversity and facilitate the transition to digital modes of delivery. Public Safety and Homeland Security Communications during emergencies and crisis must be available for public safety, health, defense, the Nations critical communications infrastructure must be reliable, interoperable, redundant, and rapidly restorable. The FCC is directed by five appointed by the President of the United States and confirmed by the United States Senate for five-year terms. The U. S. President designates one of the commissioners to serve as chairman, only three commissioners may be members of the same political party. None of them may have a financial interest in any FCC-related business, importantly, commissioners may continue serving until the appointment of their replacements, but may not serve beyond the end of the next session of Congress following term expiration. In practice, as of 2016 this means that commissioners may serve up to 1 1/2 years beyond the term expiration dates listed above if no replacement is appointed. The Consumer & Governmental Affairs Bureau develops and implements the FCCs consumer policies, CGB serves as the public face of the FCC through outreach and education, as well as through their Consumer Center, which is responsible for responding to consumer inquiries and complaints. CGB also maintains partnerships with state, local, and tribal governments in such areas as emergency preparedness. The Enforcement Bureau is responsible for enforcement of provisions of the Communications Act 1934, FCC rules, FCC orders, major areas of enforcement that are handled by the Enforcement Bureau are consumer protection, local competition, public safety, and homeland security.

Television station
–
A television station is a business, organisation or other enterprise, such as an amateur television operator, that transmits content over terrestrial television. A television transmission can occur via analog television signals or, more recently, broadcast television systems standards are set by the government, and these vary around the world. Television stations broadcasting over a system were typically limited to one television channel. The term television station is normally applied to television stations. Television stations usually require a broadcast license from a government agency which sets the requirements, most commercial television stations are owned independently, but many are either affiliated with a television network or are owned-and-operated by a television network. Another form a television station may take is non-commercial educational and considered public broadcasting, some countries have set up nationwide television networks, in which individual television stations act as mere repeaters of nationwide programs. To get a signal from the control room to the transmitter. The link can be either by radio or T1/E1, a transmitter/studio link may also send telemetry back to the station, but this may be embedded in subcarriers of the main broadcast. Stations which retransmit or simulcast another may simply pick-up that station over-the-air, the license usually specifies which other station is it allowed to carry. In North America, full-power stations on band I are generally limited to 100 kW analog video and 10 kW analog audio, stations on band III can go up by 5dB to 316 kW video,31.6 kW audio, or 160 kW digital. Low-VHF stations are subject to long-distance reception just as with FM. There are no stations on Channel 1, UHF, by comparison, has a much shorter wavelength, and thus requires a shorter antenna, but also higher power. North American stations can go up to 5000 kW ERP for video and 500 kW audio, or 1000 kW digital. Low channels travel further than high ones at the same power, despite this, in the U. S. the Federal Communications Commission is taking another large portion of this band away, in contrast to the rest of the world, which has been taking VHF instead. This means that some stations left on VHF are harder to receive after the analog shutdown, since at least 1974, there are no stations on channel 37 in North America for radio astronomy purposes. Most television stations are commercial broadcasting enterprises which are structured in a variety of ways to generate revenue from television commercials and they may be an independent station or part of a broadcasting network, or some other structure. They can produce some or all of their programs or buy some broadcast syndication programming for or all of it from other stations or independent production companies, many stations have some sort of television studio, which on major-network stations is often used for newscasts or other local programming. There is usually a department, where journalists gather information

California

California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U. S, California is bordered by the other U. S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. Los Angeles is Californias most populous city, and the second largest after New York City. The Los Angeles Area and the San Francisco Bay Area are the nations second- and fifth-most populous urban regions, California also has the nations most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The Central Valley, an agricultural area, dominates the states center. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries, the Spanish Empire then claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its war for independence. The western portion of Alta California then was organized as the State of California, the California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom. If it were a country, California would be the 6th largest economy in the world, fifty-eight percent of the states economy is centered on finance, government, real estate services, technology, and professional, scientific and technical business services. Although it accounts for only 1.5 percent of the states economy, the story of Calafia is recorded in a 1510 work The Adventures of Esplandián, written as a sequel to Amadis de Gaula by Spanish adventure writer Garci Rodríguez de Montalvo. The kingdom of Queen Calafia, according to Montalvo, was said to be a land inhabited by griffins and other strange beasts. This conventional wisdom that California was an island, with maps drawn to reflect this belief, shortened forms of the states name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, various estimates of the native population range from 100,000 to 300,000. The Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups also were diverse in their organization with bands, tribes, villages. Trade, intermarriage and military alliances fostered many social and economic relationships among the diverse groups, the first European effort to explore the coast as far north as the Russian River was a Spanish sailing expedition, led by Portuguese captain Juan Rodríguez Cabrillo, in 1542. Some 37 years later English explorer Francis Drake also explored and claimed a portion of the California coast in 1579. Spanish traders made unintended visits with the Manila galleons on their trips from the Philippines beginning in 1565

Most of the lies within the 2, 326-acre San Bruno Mountain State Park. Next to the park is the 83-acre state San Bruno Mountain Ecological Reserve on the north slope. It is near the boundary of San Francisco, surrounded by the cities of South San Francisco, Daly City, Colma. San Bruno Mountain is topped by a four mile long ridge, trails to the summit afford expansive views of the San Francisco Bay Area. The mountain provides habitat for species of rare and endangered plants. The endangered San Bruno elfin butterfly inhabits this mountain and a few other locations, the distinct Franciscan fog zone plants of San Bruno Mountain set it apart from other California coastal areas. The Portola expedition visited San Francisco Bay in 1769, the expedition is usually considered the first European presence in the area. Five years later Fernando Rivera and four soldiers climbed the mountain, the mountain was named by Bruno de Heceta for his patron saint. San Bruno Mountain consists of portions of five Mexican land grants, jose Antonio Sanchez, who rode by mule as a child from Sonora, Mexico was given Rancho Buri Buri in 1827, with confirmation in 1835. Rancho Buri Buri extended from the bay salt flats to San Andreas Valley, in 1835 this rancho was granted to Jacob P. Leese. Three other ranchos held minor portions of the flank of San Bruno Mountain. The cities that have grown up around the mountain are San Francisco to the north, Brisbane to the east, thornton pioneered the Habitat Conservation Plan concept creating the first such plan for the area around San Bruno Mountain. KRON was the first television station to place a transmitter tower on Radio Peak, in 1949, followed by KQED and KTVU, though these tenants moved their transmitters to Sutro Tower in the 1970s.

San Francisco

San Francisco, officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California. It is the birthplace of the United Nations, the California Gold Rush of 1849 brought rapid growth, making it the largest city on the West Coast at the time. San Francisco became a consolidated city-county in 1856, after three-quarters of the city was destroyed by the 1906 earthquake and fire, San Francisco was quickly rebuilt, hosting the Panama-Pacific International Exposition nine years later. In World War II, San Francisco was a port of embarkation for service members shipping out to the Pacific Theater. Politically, the city votes strongly along liberal Democratic Party lines, San Francisco is also the headquarters of five major banking institutions and various other companies such as Levi Strauss & Co. Dolby, Airbnb, Weebly, Pacific Gas and Electric Company, Yelp, Pinterest, Twitter, Uber, Lyft, Mozilla, Wikimedia Foundation, as of 2016, San Francisco is ranked high on world liveability rankings. The earliest archaeological evidence of habitation of the territory of the city of San Francisco dates to 3000 BC. Upon independence from Spain in 1821, the became part of Mexico. Under Mexican rule, the system gradually ended, and its lands became privatized. In 1835, Englishman William Richardson erected the first independent homestead, together with Alcalde Francisco de Haro, he laid out a street plan for the expanded settlement, and the town, named Yerba Buena, began to attract American settlers. Commodore John D. Sloat claimed California for the United States on July 7,1846, during the Mexican–American War, montgomery arrived to claim Yerba Buena two days later. Yerba Buena was renamed San Francisco on January 30 of the next year, despite its attractive location as a port and naval base, San Francisco was still a small settlement with inhospitable geography. The California Gold Rush brought a flood of treasure seekers, with their sourdough bread in tow, prospectors accumulated in San Francisco over rival Benicia, raising the population from 1,000 in 1848 to 25,000 by December 1849. The promise of fabulous riches was so strong that crews on arriving vessels deserted and rushed off to the gold fields, leaving behind a forest of masts in San Francisco harbor. Some of these approximately 500 abandoned ships were used at times as storeships, saloons and hotels, many were left to rot, by 1851 the harbor was extended out into the bay by wharves while buildings were erected on piles among the ships. By 1870 Yerba Buena Cove had been filled to create new land, buried ships are occasionally exposed when foundations are dug for new buildings. California was quickly granted statehood in 1850 and the U. S. military built Fort Point at the Golden Gate, silver discoveries, including the Comstock Lode in Nevada in 1859, further drove rapid population growth. With hordes of fortune seekers streaming through the city, lawlessness was common, and the Barbary Coast section of town gained notoriety as a haven for criminals, prostitution, entrepreneurs sought to capitalize on the wealth generated by the Gold Rush

Cable television
–
This contrasts with broadcast television, in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables, analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation. A cable channel is a television network available via cable television, alternative terms include non-broadcast channel or programming service, the latter being mainly used in legal contexts. Examples of cable/satellite channels/cable networks available in many countries are HBO, MTV, Cartoon Network, E. Eurosport, the abbreviation CATV is often used for cable television. It originally stood for Community Access Television or Community Antenna Television, in areas where over-the-air TV reception was limited by distance from transmitters or mountainous terrain, large community antennas were constructed, and cable was run from them to individual homes. The origins of cable broadcasting for radio are even older as radio programming was distributed by cable in some European cities as far back as 1924, Cable television has gone through a series of steps of evolution in the United States and Canada. Particularly in Canada, communities with their own signals were fertile cable markets, as viewers wanted to receive American signals. Early systems carried only a maximum of seven channels, using 2,4,5 or 6,7,9,11 and 13, as the equipment was unable to confine the signal discreetly within the assigned channel bandwidth. The reason 4 and 5 along with 6 and 7 could be used together was because of the 4 MHz gap between 4 and 5 and the nearly 90 MHz gap between 6 and 7. Even though eight channels are listed, in systems that maximized 7 channels. As equipment improved, all channels could be utilized, except where a local VHF television station broadcast. Local broadcast channels were not usable for signals deemed to be priority, later, the cable operators began to carry FM radio stations, and encouraged subscribers to connect their FM stereo sets to cable. Before stereo and bilingual TV sound became common, Pay-TV channel sound was added to the FM stereo cable line-ups, about this time, operators expanded beyond the 12-channel dial to use the midband and superband VHF channels adjacent to the high band 7-13 of North American television frequencies. Some operators as in Cornwall, Ontario, used a dual distribution network with Channels 2-13 on each of the two cables, during the 1980s, United States regulations not unlike public, educational, and government access created the beginning of cable-originated live television programming. These stations evolved partially into todays over-the-air digital subchannels, where a main broadcast TV station e. g, many live local programs with local interests were subsequently created all over the United States in most major television markets in the early 1980s. This evolved into todays many cable-only broadcasts of diverse programming, including cable-only produced television movies and miniseries, Cable specialty channels, starting with channels oriented to show movies and large sporting or performance events, diversified further, and narrowcasting became common. By the late 1980s, cable-only signals outnumbered broadcast signals on cable systems, by the mid-1980s in Canada, cable operators were allowed by the regulator to enter into distribution contracts with cable networks on their own. By the 1990s, tiers became common, with customers able to subscribe to different tiers to obtain different selections of additional channels above the basic selection, by subscribing to additional tiers, customers could get specialty channels, movie channels, and foreign channels

Monterey, California
–
The City of Monterey in Monterey County is located on the southern edge of Monterey Bay, in the Northern Portion of Californias Central Coast. It stands at an elevation of 26 feet above sea level, the 2010 census recorded a population of 27,810. Monterey was the capital of Alta California under both Spain and Mexico and it was the only port of entry for taxable goods in California. In 1846 the U. S. flag was raised over the Customs House, the city had Californias first theater, public building, public library, publicly funded school, printing press, and newspaper. The city and surrounding area have attracted artists since the late 19th century, until the 1950s, there was an abundant fishery. Among Montereys notable present-day attractions are the Monterey Bay Aquarium, Cannery Row, Fishermans Wharf, long before the arrival of Spanish explorers, the Rumsen Ohlone tribe, one of seven linguistically distinct Ohlone groups in California, inhabited the area now known as Monterey. They subsisted by hunting, fishing and gathering food on and around the biologically rich Monterey Peninsula, researchers have found a number of shell middens in the area and, based on the archaeological evidence, concluded the Ohlones primary marine food consisted at various times of mussels and abalone. A number of sites have been located along about 12 miles of rocky coast on the Monterey Peninsula from the current site of Fishermans Wharf in Monterey to Carmel. In 1602, Spanish maritime explorer Sebastian Vizcaino recorded the name Bahía de Monterrey, Vizcaino landed at the southern end of the bay and described a great port, suitable for use as an anchorage by southbound Manila galleons. Vizcaino also noted and named the Point of Pines, all other uses of the name Monterey derive from Vizcainos name for the bay. Variants of the name are recorded as Monte Rey and Montery. In 1769, the first European land exploration of Alta California, for some reason, the explorers failed to recognize the place when they came to it on October 1,1769. The party continued north as far as San Francisco Bay before turning back, on the return journey, they camped near one of Montereys lagoons on November 27, still not convinced they had found the place Vizcaino had described. Franciscan missionary Juan Crespí noted in his diary, We halted in sight of the Point of Pines and camped near a lagoon which has rather muddy water. Portolá returned by land to Monterey the next year, having concluded that he must have been at Vizcainos Port of Monterey after all, the land party was met at Monterey by Junípero Serra who traveled by sea. Portolá erected the Presidio of Monterey to defend the port and, on June 3,1770, Portolá returned to Mexico, replaced in Monterey by Captain Pedro Fages, who had been third in command on the exploratory expeditions. Fages became the governor of Alta California, serving from 1770 to 1774. Serras missionary aims soon came into conflict with Fages and the soldiers, the existing wood and adobe building became the chapel for the Presidio

Loma Prieta is a 3,790 feet Northern California mountain in the Santa Cruz Mountains. The peak is on private property about 11 miles west of Morgan Hill in Santa Clara County, the dirt road to the summit is gated, but the tower maintainers generally do not mind hikers. A rural area south and east of the summit is referred to as Casa Loma. The name is unofficial, but its use is supported by the existence of a Casa Loma Volunteer Fire Department in the area, Loma Chiquita Road also serves this general area near the Santa Cruz County line. From 1976 through 1990 amateur astronomer Donald Machholz set up his telescope an average of 120 times a year on the slope of this mountain to search for comets. From this site he discovered three new comets that bear his name, including Periodic Comet Machholz 1 96P/Machholz on May 12,1986, the first official West Coast Messier marathon was conducted from this site in March 1979. The epicenter of the 1989 Loma Prieta earthquake was near the mountain, the mountain was the longtime site for the transmitter tower of San Jose television station KNTV. It moved its transmitter 83 kilometres northwest to San Bruno Mountain in September 2005, Loma Prieta is the tallest peak in the Santa Cruz Mountains and thus it is common to see snow on the mountain during the winter.

CBS

CBS is an American commercial broadcast television network that is a flagship property of CBS Corporation. The company is headquartered at the CBS Building in New York City with major facilities and operations in New York City. CBS is sometimes referred to as the Eye Network, in reference to the iconic logo. It has also called the Tiffany Network, alluding to the perceived high quality of CBS programming during the tenure of William S. Paley. It can also refer to some of CBSs first demonstrations of color television, the network has its origins in United Independent Broadcasters Inc. a collection of 16 radio stations that was purchased by Paley in 1928 and renamed the Columbia Broadcasting System. Under Paleys guidance, CBS would first become one of the largest radio networks in the United States, in 1974, CBS dropped its former full name and became known simply as CBS, Inc. In 2000, CBS came under the control of Viacom, which was formed as a spin-off of CBS in 1971, CBS Corporation is controlled by Sumner Redstone through National Amusements, which also controls the current Viacom. The television network has more than 240 owned-and-operated and affiliated stations throughout the United States. The origins of CBS date back to January 27,1927, Columbia Phonographic went on the air on September 18,1927, with a presentation by the Howard Barlow Orchestra from flagship station WOR in Newark, New Jersey, and fifteen affiliates. Operational costs were steep, particularly the payments to AT&T for use of its land lines, in early 1928 Judson sold the network to brothers Isaac and Leon Levy, owners of the networks Philadelphia affiliate WCAU, and their partner Jerome Louchenheim. With the record out of the picture, Paley quickly streamlined the corporate name to Columbia Broadcasting System. He believed in the power of advertising since his familys La Palina cigars had doubled their sales after young William convinced his elders to advertise on radio. By September 1928, Paley bought out the Louchenheim share of CBS, during Louchenheims brief regime, Columbia paid $410,000 to A. H. Grebes Atlantic Broadcasting Company for a small Brooklyn station, WABC, which would become the networks flagship station. WABC was quickly upgraded, and the relocated to 860 kHz. The physical plant was relocated also – to Steinway Hall on West 57th Street in Manhattan, by the turn of 1929, the network could boast to sponsors of having 47 affiliates. Paley moved right away to put his network on a financial footing. In the fall of 1928, he entered talks with Adolph Zukor of Paramount Pictures. The deal came to fruition in September 1929, Paramount acquired 49% of CBS in return for a block of its stock worth $3.8 million at the time

DuMont Television Network
–
The DuMont Television Network was one of the worlds pioneer commercial television networks, rivalling NBC and CBS for the distinction of being first overall in the United States. It was owned by DuMont Laboratories, an equipment and set manufacturer. DuMont Laboratories was founded in 1931 by Dr. Allen B, DuMont with only $1,000, and a laboratory in his basement. He and his staff were responsible for many technical innovations. The companys television sets became the gold standard of the industry. In 1942, DuMont worked with the Army in developing radar technology during World War II and this brought in $5 million for the company. Early sales of television sets were hampered by the lack of regularly scheduled programming being broadcast, a few months after selling his first set in 1938, DuMont opened his own New York area experimental television station in Passaic, New Jersey. In 1940, the moved to Manhattan as W2XWV on channel 4. Unlike CBS and NBC, which reduced their hours of television broadcasting during World War II, in 1944, W2XWV became WABD moving to channel 5 in 1945, the third commercial television station in New York. On May 19,1945, DuMont opened experimental W3XWT in Washington, a minority shareholder in DuMont Laboratories was Paramount Pictures, which had advanced $400,000 in 1939 for a 40% share in the company. Soon after his experimental Washington station signed on, DuMont began experimental coaxial cable hookups between his laboratories in Passaic, New Jersey, and his two stations. It is said one of those broadcasts on the hookup announced that the U. S. had dropped an atomic bomb on Nagasaki, Japan. This was later considered to be the beginning of the DuMont Network by both Thomas T. Goldsmith, the networks chief engineer and DuMonts best friend, and DuMont himself. Regular network service began on August 15,1946, on WABD, in 1947, W3XWT became WTTG, named after Goldsmith. The pair were joined in 1949 by WDTV in Pittsburgh, ABC had just come into existence as a radio network in 1943 and did not enter network television until 1948, when it signed on a flagship station in New York City, WJZ-TV. CBS also waited until 1948 to begin network operations because it was waiting for the Federal Communications Commission to approve its color television system, despite no history of radio programming or stable of radio stars to draw on and perennial cash shortages, DuMont was an innovative and creative network. Without the radio revenues that supported mighty NBC and CBS, DuMont programmers relied on their wits, eventually, the network provided original programs that are remembered more than 60 years later. The network largely ignored the standard model of 1950s TV, in which one advertiser sponsored an entire show
