Television, sometimes shortened to tele or telly, is a telecommunication medium used for transmitting moving images in monochrome, or in color, in two or three dimensions and sound. The term can refer to a television set, a television program, or the medium of television transmission. Television is a mass medium for advertising and news. Television became available in crude experimental forms in the late 1920s, but it would still be several years before the new technology would be marketed to consumers. After World War II, an improved form of black-and-white TV broadcasting became popular in the United States and Britain, television sets became commonplace in homes and institutions. During the 1950s, television was the primary medium for influencing public opinion. In the mid-1960s, color broadcasting was introduced in most other developed countries; the availability of multiple types of archival storage media such as Betamax, VHS tape, local disks, DVDs, flash drives, high-definition Blu-ray Discs, cloud digital video recorders has enabled viewers to watch pre-recorded material—such as movies—at home on their own time schedule.
For many reasons the convenience of remote retrieval, the storage of television and video programming now occurs on the cloud. At the end of the first decade of the 2000s, digital television transmissions increased in popularity. Another development was the move from standard-definition television to high-definition television, which provides a resolution, higher. HDTV may be transmitted in various formats: 1080p, 720p. Since 2010, with the invention of smart television, Internet television has increased the availability of television programs and movies via the Internet through streaming video services such as Netflix, Amazon Video, iPlayer and Hulu. In 2013, 79 % of the world's households owned; the replacement of early bulky, high-voltage cathode ray tube screen displays with compact, energy-efficient, flat-panel alternative technologies such as LCDs, OLED displays, plasma displays was a hardware revolution that began with computer monitors in the late 1990s. Most TV sets sold in the 2000s were flat-panel LEDs.
Major manufacturers announced the discontinuation of CRT, DLP, fluorescent-backlit LCDs by the mid-2010s. In the near future, LEDs are expected to be replaced by OLEDs. Major manufacturers have announced that they will produce smart TVs in the mid-2010s. Smart TVs with integrated Internet and Web 2.0 functions became the dominant form of television by the late 2010s. Television signals were distributed only as terrestrial television using high-powered radio-frequency transmitters to broadcast the signal to individual television receivers. Alternatively television signals are distributed by coaxial cable or optical fiber, satellite systems and, since the 2000s via the Internet; until the early 2000s, these were transmitted as analog signals, but a transition to digital television is expected to be completed worldwide by the late 2010s. A standard television set is composed of multiple internal electronic circuits, including a tuner for receiving and decoding broadcast signals. A visual display device which lacks a tuner is called a video monitor rather than a television.
The word television comes from Ancient Greek τῆλε, meaning'far', Latin visio, meaning'sight'. The first documented usage of the term dates back to 1900, when the Russian scientist Constantin Perskyi used it in a paper that he presented in French at the 1st International Congress of Electricity, which ran from 18 to 25 August 1900 during the International World Fair in Paris; the Anglicised version of the term is first attested in 1907, when it was still "...a theoretical system to transmit moving images over telegraph or telephone wires". It was "...formed in English or borrowed from French télévision." In the 19th century and early 20th century, other "...proposals for the name of a then-hypothetical technology for sending pictures over distance were telephote and televista." The abbreviation "TV" is from 1948. The use of the term to mean "a television set" dates from 1941; the use of the term to mean "television as a medium" dates from 1927. The slang term "telly" is more common in the UK; the slang term "the tube" or the "boob tube" derives from the bulky cathode ray tube used on most TVs until the advent of flat-screen TVs.
Another slang term for the TV is "idiot box". In the 1940s and throughout the 1950s, during the early rapid growth of television programming and television-set ownership in the United States, another slang term became used in that period and continues to be used today to distinguish productions created for broadcast on television from films developed for presentation in movie theaters; the "small screen", as both a compound adjective and noun, became specific references to television, while the "big screen" was used to identify productions made for theatrical release. Facsimile transmission systems for still photographs pioneered methods of mechanical scanning of images in the early 19th century. Alexander Bain introduced the facsimile machine between 1843 and 1846. Frederick Bakewell demonstrated a working laboratory version in 1851. Willoughby Smith discovered the photoconductivity of the element selenium in 1873; as a 23-year-old German university student, Paul Julius Gottlieb Nipkow proposed and patented the Nipkow disk in 1884.
This was a spinning disk with a spiral pattern of holes in it, so each hole scanned a line of the image. Although he never built a working model
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous 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 and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
CBS is an American English language commercial broadcast television and radio network, a flagship property of CBS Corporation. The company is headquartered at the CBS Building in New York City with major production facilities and operations in New York City and Los Angeles. CBS is sometimes referred to as the Eye Network, in reference to the company's iconic symbol, in use since 1951, it has been called the "Tiffany Network", alluding to the perceived high quality of CBS programming during the tenure of William S. Paley, it can refer to some of CBS's first demonstrations of color television, which were held in a former Tiffany & Co. building in New York City in 1950. The network has its origins in United Independent Broadcasters Inc. a collection of 16 radio stations, purchased by Paley in 1928 and renamed the Columbia Broadcasting System. Under Paley's guidance, CBS would first become one of the largest radio networks in the United States, one of the Big Three American broadcast television networks.
In 1974, CBS dropped its former full name and became known as CBS, Inc. The Westinghouse Electric Corporation acquired the network in 1995, renamed its corporate entity to the current CBS Broadcasting, Inc. in 1997, adopted the name of the company it had acquired to become CBS Corporation. In 2000, CBS came under the control of Viacom, formed as a spin-off of CBS in 1971. In late 2005, Viacom split itself into two separate companies and re-established CBS Corporation – through the spin-off of its broadcast television and select cable television and non-broadcasting assets – with the CBS television network at its core. CBS Corporation is controlled by Sumner Redstone through National Amusements, which controls the current Viacom. CBS operated the CBS Radio network until 2017, when it merged its radio division with Entercom. Prior to CBS Radio provided news and features content for its portfolio owned-and-operated radio stations in large and mid-sized markets, affiliated radio stations in various other markets.
While CBS Corporation owns a 72% stake in Entercom, it no longer owns or operates any radio stations directly, though CBS still provides radio news broadcasts to its radio affiliates and the new owners of its former radio stations. The television network has more than 240 owned-and-operated and affiliated television stations throughout the United States; the company ranked 197th on the 2018 Fortune 500 of the largest United States corporations by revenue. The origins of CBS date back to January 27, 1927, with the creation of the "United Independent Broadcasters" network in Chicago by New York City talent-agent Arthur Judson; the fledgling network soon needed additional investors though, the Columbia Phonograph Company, manufacturers of Columbia Records, rescued it in April 1927. Columbia Phonographic went on the air on September 18, 1927, with a presentation by the Howard L. Barlow Orchestra from flagship station WOR in Newark, New Jersey, fifteen affiliates. Operational costs were steep the payments to AT&T for use of its land lines, by the end of 1927, Columbia Phonograph wanted out.
In early 1928 Judson sold the network to brothers Isaac and Leon Levy, owners of the network's Philadelphia affiliate WCAU, their partner Jerome Louchheim. None of the three were interested in assuming day-to-day management of the network, so they installed wealthy 26-year-old William S. Paley, son of a Philadelphia cigar family and in-law of the Levys, as president. With the record company out of the picture, Paley streamlined the corporate name to "Columbia Broadcasting System", he believed in the power of radio advertising since his family's "La Palina" cigars had doubled their sales after young William convinced his elders to advertise on radio. By September 1928, Paley bought out the Louchhheim share of CBS and became its majority owner with 51% of the business. During Louchheim's brief regime, Columbia paid $410,000 to A. H. Grebe's Atlantic Broadcasting Company for a small Brooklyn station, WABC, which would become the network's flagship station. WABC was upgraded, the signal relocated to 860 kHz.
The physical plant was relocated – to Steinway Hall on West 57th Street in Manhattan, where much of CBS's programming would originate. 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 firmer financial footing. In the fall of 1928, he entered into talks with Adolph Zukor of Paramount Pictures, who planned to move into radio in response to RCA's forays into motion pictures with the advent of talkies; 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. The agreement specified that Paramount would buy that same stock back by March 1, 1932 for a flat $5 million, provided CBS had earned $2 million during 1931 and 1932. For a brief time there was talk that the network might be renamed "Paramount Radio", but it only lasted a month – the 1929 stock market crash sent all stock value tumbling, it galvanized Paley and his troops, who "had no alternative but to turn the network around and earn the $2,000,000 in two years....
This is the atmosphere in which the CBS of today was born." The near-bankrupt movie studio sold its CBS shares back to CBS in 1932. In the first year of Paley's wa
Prévost is a Quebec, Canada-based manufacturer of touring coaches and bus shells for high-end motorhomes and specialty conversions. The company is a subsidiary of Volvo; the company was founded in 1924 by Eugène Prévost, a cabinet maker specializing in church pews and school furniture, who in 1924 was asked to build a custom bus body for a new REO truck chassis. Les Ateliers Prévost, as the company was called, received several repeat orders. Between 1937 and 1939, Prévost Car's first bus manufacturing plant was built; the vehicles were built around a wooden frame. In 1945 this changed, bodies were made of metal; the company was acquired by Paul Normand in 1957. In 1969, two American businessmen formed a partnership with André Normand President of Prévost, to become the company’s owners; these three men, in turn, sold Prévost to Volvo Bus Corporation in 1995. As of February 2007, the firm has 1,337 employees and operates six parts and service centres in North America; the latest models saw the XLII revised, with a longer wheelbase for more storage and a smoother ride.
This, other changes, marked the beginning of the new X3-45. The flagship H3-45 received some further enhancements in 2006 with destination sign options. In addition, the new Delta sound system was developed to provide improved sound throughout the cabin. For the new EPA 2007 Standards, Prévost now offers an innovative installation of the Diesel Particulate Filter and the Rooftop Diffuser for Increased Safety, Performance and Security; the standard Detroit Diesel has been uprated from 12.7 litres to 14 litres for the model year 2007. For the 2008 model year, Prévost introduced a new Volvo D13 engine from their parent company as a replacement for the then-current Detroit Diesel Series 60 offering; the Volvo I-Shift semiautomatic transmission was introduced as an option to the Allison B500R transmission. A set of new interior colour schemes were developed for the 2008 model year to provide a modern feel. There are three "trim levels" ranging from fabric to wood. Beginning with 2011, the Prevost X3-45 is available in a transit configuration, with bi-fold doors instead of a sedan-type door.
The New York City Transit Authority is the launch customer for this configuration. 20 transit-style buses in the LeMirage predecessor model had been built for GO Transit in the late 1990s.
