The film industry or motion picture industry, comprises the technological and commercial institutions of filmmaking, i.e. film production companies, film studios, animation, film production, pre-production, post production, film festivals and actors, film directors and other film crew personnel. Though the expense involved in making films immediately led film production to concentrate under the auspices of standing production companies, advances in affordable film making equipment, expansion of opportunities to acquire investment capital from outside the film industry itself, have allowed independent film production to evolve; as of 2018, the global box office is worth $41.7 billion. When including box office and home entertainment revenue, the global film industry is worth $136 billion as of 2018. Hollywood is the world's oldest national film industry, remains the largest in terms of box office gross revenue. Indian cinema is the largest national film industry in terms of the number of films produced and the number of tickets sold, with 3.5 billion tickets sold worldwide annually and 1,986 feature films produced annually.
The worldwide theatrical market had a box office of US$38.6 billion in 2016. The top three continents/regions by box office gross were: Asia-Pacific with US$14.9 billion, the U. S. and Canada with US$11.4 billion, Europe, the Middle East and North Africa with US$9.5 billion. As of 2016, the largest markets by box office were, in decreasing order, the United States, Japan and the United Kingdom; as of 2011, the countries with the largest number of film productions were India and the United States. In Europe, significant centers of movie production are France, Italy and the United Kingdom. Distinct from the centers are the locations; because of labor and infrastructure costs, many films are produced in countries other than the one in which the company which pays for the film is located. For example, many U. S. films are filmed in Canada, many Nigerian films are filmed in Ghana, while many Indian films are filmed in the Americas, Singapore etc. The cinema of the United States generally referred to as Hollywood, has had a profound effect on cinema across the world since the early 20th century.
The United States cinema is the oldest film industry in the world which originated more than 121 years ago and the largest film industry in terms of revenue. Hollywood is the primary nexus of the U. S. film industry with established film study facilities such as the American Film Institute, LA Film School and NYFA being established in the area. However, four of the six major film studios are owned by East Coast companies; the major film studios of Hollywood including Metro-Goldwyn-Mayer, 20th Century Fox, Paramount Pictures are the primary source of the most commercially successful movies in the world, such as Star Wars, Titanic. American film studios today collectively generate several hundred films every year, making the United States one of the most prolific producers of films in the world. Only The Walt Disney Company — which owns the Walt Disney Studios — is based in Southern California, and while Sony Pictures Entertainment is headquartered in Culver City, its parent company, the Sony Corporation, is headquartered in Tokyo, Japan.
Most shooting now takes place in California, New York, Louisiana and North Carolina. Hollywood is the most popular film industry with the highest number of screens, is the highest-grossing film industry in the world. Between 2009-2015, Hollywood grossed $10 billion annually. Hollywood's award ceremony, the Academy Awards known as The Oscars, is held by the Academy of Motion Picture Arts and Sciences every year and a total of 2,947 Oscars have been awarded since the inception of the award; the earliest documented account of an exhibition of projected motion pictures in the United States was in June 1894 in Richmond, Indiana by Charles Francis Jenkins which makes United States cinema the earliest cinema in the whole world. Jenkins used his Phantoscope to project his film before an audience of family and reporters; the film featured a vaudeville dancer performing a Butterfly Dance. Jenkins and his new partner Thomas Armat modified the Phantoscope for exhibitions in temporary theaters at the Cotton States Exposition in the fall of 1895.
The was sold to Thomas Edison, who changed the name of the projector to Edison's Vitascope. Nestor Studios was Hollywood's first film studio, founded on 27 October 1911, it was built by David Horsley for Nestor Motion Picture Company. It was owned and operated by David Horsley and his brother, William Horsley; the first motion picture stage in Hollywood was built behind the tavern. Other East Coast studios had moved production to Los Angeles, prior to Nestor's move west; the California weather allowed for year-round filming and the ambitious studio operated three principal divisions under its Canadian-born general manager, Al Christie. Other filmmakers began opening studios in the Hollywood area; the Horsleys operated the Nestor Studios at the Sunset and Gower location until 20 May 1912, when the Universal Studios was formed, headed by Carl Laemmle. Nestor, along with several other motion picture companies, including Laemmle's Independent Moving Pictures, was merged with Universal; the Cinema of China is one of three distinct historical threads of Chinese-language cinema together with the cinema of Hong Kong and the cinema of Taiwan.
Cinema was introduced in China in 1896 and the first Chinese film, Dingjun Mountain, was made in 1905, with the film industry being cent
International Standard Serial Number
An International Standard Serial Number is an eight-digit serial number used to uniquely identify a serial publication, such as a magazine. The ISSN is helpful in distinguishing between serials with the same title. ISSN are used in ordering, interlibrary loans, other practices in connection with serial literature; the ISSN system was first drafted as an International Organization for Standardization international standard in 1971 and published as ISO 3297 in 1975. ISO subcommittee TC 46/SC 9 is responsible for maintaining the standard; when a serial with the same content is published in more than one media type, a different ISSN is assigned to each media type. For example, many serials are published both in electronic media; the ISSN system refers to these types as electronic ISSN, respectively. Conversely, as defined in ISO 3297:2007, every serial in the ISSN system is assigned a linking ISSN the same as the ISSN assigned to the serial in its first published medium, which links together all ISSNs assigned to the serial in every medium.
The format of the ISSN is an eight digit code, divided by a hyphen into two four-digit numbers. As an integer number, it can be represented by the first seven digits; the last code digit, which may be 0-9 or an X, is a check digit. Formally, the general form of the ISSN code can be expressed as follows: NNNN-NNNC where N is in the set, a digit character, C is in; the ISSN of the journal Hearing Research, for example, is 0378-5955, where the final 5 is the check digit, C=5. To calculate the check digit, the following algorithm may be used: Calculate the sum of the first seven digits of the ISSN multiplied by its position in the number, counting from the right—that is, 8, 7, 6, 5, 4, 3, 2, respectively: 0 ⋅ 8 + 3 ⋅ 7 + 7 ⋅ 6 + 8 ⋅ 5 + 5 ⋅ 4 + 9 ⋅ 3 + 5 ⋅ 2 = 0 + 21 + 42 + 40 + 20 + 27 + 10 = 160 The modulus 11 of this sum is calculated. For calculations, an upper case X in the check digit position indicates a check digit of 10. To confirm the check digit, calculate the sum of all eight digits of the ISSN multiplied by its position in the number, counting from the right.
The modulus 11 of the sum must be 0. There is an online ISSN checker. ISSN codes are assigned by a network of ISSN National Centres located at national libraries and coordinated by the ISSN International Centre based in Paris; the International Centre is an intergovernmental organization created in 1974 through an agreement between UNESCO and the French government. The International Centre maintains a database of all ISSNs assigned worldwide, the ISDS Register otherwise known as the ISSN Register. At the end of 2016, the ISSN Register contained records for 1,943,572 items. ISSN and ISBN codes are similar in concept. An ISBN might be assigned for particular issues of a serial, in addition to the ISSN code for the serial as a whole. An ISSN, unlike the ISBN code, is an anonymous identifier associated with a serial title, containing no information as to the publisher or its location. For this reason a new ISSN is assigned to a serial each time it undergoes a major title change. Since the ISSN applies to an entire serial a new identifier, the Serial Item and Contribution Identifier, was built on top of it to allow references to specific volumes, articles, or other identifiable components.
Separate ISSNs are needed for serials in different media. Thus, the print and electronic media versions of a serial need separate ISSNs. A CD-ROM version and a web version of a serial require different ISSNs since two different media are involved. However, the same ISSN can be used for different file formats of the same online serial; this "media-oriented identification" of serials made sense in the 1970s. In the 1990s and onward, with personal computers, better screens, the Web, it makes sense to consider only content, independent of media; this "content-oriented identification" of serials was a repressed demand during a decade, but no ISSN update or initiative occurred. A natural extension for ISSN, the unique-identification of the articles in the serials, was the main demand application. An alternative serials' contents model arrived with the indecs Content Model and its application, the digital object identifier, as ISSN-independent initiative, consolidated in the 2000s. Only in 2007, ISSN-L was defined in the
A magazine is a publication a periodical publication, printed or electronically published. Magazines are published on a regular schedule and contain a variety of content, they are financed by advertising, by a purchase price, by prepaid subscriptions, or a combination of the three. At its root, the word "magazine" refers to a storage location. In the case of written publication, it is a collection of written articles; this explains why magazine publications share the word root with gunpowder magazines, artillery magazines, firearms magazines, and, in French, retail stores such as department stores. By definition, a magazine paginates with each issue starting at page three, with the standard sizing being 8 3⁄8 in × 10 7⁄8 in. However, in the technical sense a journal has continuous pagination throughout a volume, thus Business Week, which starts each issue anew with page one, is a magazine, but the Journal of Business Communication, which starts each volume with the winter issue and continues the same sequence of pagination throughout the coterminous year, is a journal.
Some professional or trade publications are peer-reviewed, an example being the Journal of Accountancy. Academic or professional publications that are not peer-reviewed are professional magazines; that a publication calls itself a journal does not make it a journal in the technical sense. Magazines can be distributed through the mail, through sales by newsstands, bookstores, or other vendors, or through free distribution at selected pick-up locations; the subscription business models for distribution fall into three main categories. In this model, the magazine is sold to readers for a price, either on a per-issue basis or by subscription, where an annual fee or monthly price is paid and issues are sent by post to readers. Paid circulation allows for defined readership statistics; this means that there is no cover price and issues are given away, for example in street dispensers, airline, or included with other products or publications. Because this model involves giving issues away to unspecific populations, the statistics only entail the number of issues distributed, not who reads them.
This is the model used by many trade magazines distributed only to qualifying readers for free and determined by some form of survey. Because of costs associated with the medium of print, publishers may not distribute free copies to everyone who requests one; this allows a high level of certainty that advertisements will be received by the advertiser's target audience, it avoids wasted printing and distribution expenses. This latter model was used before the rise of the World Wide Web and is still employed by some titles. For example, in the United Kingdom, a number of computer-industry magazines use this model, including Computer Weekly and Computing, in finance, Waters Magazine. For the global media industry, an example would be VideoAge International; the earliest example of magazines was Erbauliche Monaths Unterredungen, a literary and philosophy magazine, launched in 1663 in Germany. The Gentleman's Magazine, first published in 1731, in London was the first general-interest magazine. Edward Cave, who edited The Gentleman's Magazine under the pen name "Sylvanus Urban", was the first to use the term "magazine," on the analogy of a military storehouse.
Founded by Herbert Ingram in 1842, The Illustrated London News was the first illustrated magazine. The oldest consumer magazine still in print is The Scots Magazine, first published in 1739, though multiple changes in ownership and gaps in publication totalling over 90 years weaken that claim. Lloyd's List was founded in Edward Lloyd's England coffee shop in 1734. Under the ancient regime, the most prominent magazines were Mercure de France, Journal des sçavans, founded in 1665 for scientists, Gazette de France, founded in 1631. Jean Loret was one of France's first journalists, he disseminated the weekly news of music and Parisian society from 1650 until 1665 in verse, in what he called a gazette burlesque, assembled in three volumes of La Muse historique. The French press lagged a generation behind the British, for they catered to the needs the aristocracy, while the newer British counterparts were oriented toward the middle and working classes. Periodicals were censored by the central government in Paris.
They were not quiescent politically—often they criticized Church abuses and bureaucratic ineptitude. They supported the monarchy and they played at most a small role in stimulating the revolution. During the Revolution, new periodicals played central roles as propaganda organs for various factions. Jean-Paul Marat was the most prominent editor, his L'Ami du peuple advocated vigorously for the rights of the lower classes against the enemies of the people Marat hated. After 1800 Napoleon reimposed strict censorship. Magazines flourished after Napoleon left in 1815. Most were based in Paris and most emphasized literature and stories, they served religious and political communities. In times of political crisis they expressed and helped shape the views of their readership and thereby were major
A box office or ticket office is a place where tickets are sold to the public for admission to an event. Patrons may perform the transaction at a countertop, through a hole in a wall or window, or at a wicket. By extension, the term is used in the context of the film industry, as a synonym for the amount of business a particular production, such as a film or theatre show, receives. Box office business can be measured in the terms of the number of tickets sold or the amount of money raised by ticket sales; the projection and analysis of these earnings is important for the creative industries and a source of interest for fans. This is predominant in the Hollywood movie industry; the term is attested since 1786 from sales of boxes. The sense of "total sales" is attested from 1904. A folk etymology is that this derives from Elizabethan theatre, where theatre admission was collected in a box attached to a long stick, passed around the audience. However, first attestation is about 200 years making this unlikely.
There are numerous websites that monitor box-office receipts, such as BoxOffice, Box Office India, Box Office Mojo, ShowBIZ Data and The Numbers which provide detailed information for many movies but have less and incomplete data for older movies due to the history of how box office reporting evolved in the U. S. and the availability of this information prior to the introduction of the internet. Although other publications have published box office data over the years, the longevity and regular reporting of Variety makes it a significant source for older box office reporting for the US market and US films. During the 1920s, Variety reported box office grosses for films by theatre for certain U. S. cities. In 1946, they started to publish a weekly National Box Office survey on page 3 indicating the performance of the week's hits and flops based on the box office results of 25 key U. S. cities. During the 1930s, Variety published charts of the top performing films of the year and has maintained this tradition annually since.
In 1946, they published a list of All-Time Top Grossers with a list of films that had achieved or gave promise of earning $4,000,000 or more in domestic rentals. They would publish an updated all-time list annually for over 50 years in their anniversary edition each January; the anniversary edition would normally contain the list of the top performing films of the year. Some publications such as BoxOffice magazine published box office performance expressed as a percentage compared to regular films Some of the early annual reports from Variety used this format. From the 1930s, BoxOffice magazine published a Barometer issue in January giving the performance of movies for the year expressed as percentages; the first issue of The Motion Picture Almanac in 1929 used this format to rank money makers. In the late 1960s, Variety used an IBM 360 computer to collate the grosses from their weekly reports of 22 to 24 U. S. cities from January 1, 1968. The data came from up to 800 theatres which represented around 5% of the U.
S. cinema population at the time but around one-third of the total U. S. box office grosses. In 1969, they started to publish the computerized box office compilation of the top 50 grossing films of the week based on this data. "The Love Bug" was the number one in the first chart published for the week ending April 16, 1969. The chart was discontinued in 1990. In 1976, Marcy Polier, an employee of the Mann theater chain, set up Centralized Grosses to collate U. S. daily box office data on a centralized basis rather than each theater chain collating their own numbers from other theater chains. The company became National Gross Service Entertainment Data, Inc.. Except for disclosures by the studios on successful films, total domestic box office gross information for films was not available until National Gross Service started to collate this data around 1981; the collation of grosses led to wider reporting of domestic box office grosses for films. Arthur D. Murphy at Variety was one of the first to organize and chart that information and report it in a meaningful form.
During the 1980s, Daily Variety started to publish a weekly chart of the domestic box office grosses of films as compared to the Top 50 chart in Variety, based on a sample of key markets. The focus of a film's performance became its box office gross rather than the rentals that Variety continued to report annually. Prior to the tracking of these grosses, domestic or worldwide box office grosses is not available for many earlier films so the only domestic or worldwide data available is still the rental figures. In 1984, EDI started to report Canadian grosses as well and by 1985 was reporting data for 15,000 screens. In 1987, EDI set up a database of box office information which included data on certain films back to 1970. By 1991, all U. S. studios had agreed to share their complete data reports with EDI. In 1990, EDI opened an office in the UK, moved into Germany in 1993 and Spain in 1995 reporting box office data for those markets. EDI were acquired by ACNielsen Corporation in 1997 for $26 million and became Nielsen EDI.
In December 2009, with its acquisition of Nielsen EDI for $15 million, measurement company Rentrak became the sole provider of worldwide box office ticket sales revenue and attendance information, used by many of the websites noted above. For a list of films which are major box-office hits, see List of highest-grossing films. Films that are considered to have been unsuccessful at the box office are called box office bombs or box off
A movie theater, cinema, or cinema hall known as a picture house or the pictures, is a building that contains an auditorium for viewing films for entertainment. Most, but not all, theaters are commercial operations catering to the general public, who attend by purchasing a ticket; some movie theaters, are operated by non-profit organizations or societies that charge members a membership fee to view films. The film is projected with a movie projector onto a large projection screen at the front of the auditorium while the dialogue and music are played through a number of wall-mounted speakers. Since the 1970s, subwoofers have been used for low-pitched sounds. In the 2010s, most movie theaters are equipped for digital cinema projection, removing the need to create and transport a physical film print on a heavy reel. A great variety of films are shown at cinemas, ranging from animated films to blockbusters to documentaries; the smallest movie theaters have a single viewing room with a single screen.
In the 2010s, most movie theaters have multiple screens. The largest theater complexes, which are called multiplexes—a design developed in the US in the 1960s—have up to thirty screens; the audience members sit on padded seats, which in most theaters are set on a sloped floor, with the highest part at the rear of the theater. Movie theaters sell soft drinks and candy, some theaters sell hot fast food. In some jurisdictions, movie theaters can be licensed to sell alcoholic drinks. A movie theater may be referred to as a movie theatre, movie house, film house, film theater or picture house. In the US, theater has long been the preferred spelling, while in the UK, Australia and elsewhere it is theatre. However, some US theaters opt to use the British spelling in their own names, a practice supported by the National Association of Theatre Owners, while apart from North America most English-speaking countries use the term cinema, alternatively spelled and pronounced kinema; the latter terms, as well as their derivative adjectives "cinematic" and "kinematic" derive from Greek κινῆμα, κινήματος —"movement", "motion".
In the countries where those terms are used, the word "theatre" is reserved for live performance venues. Colloquial expressions applied to motion pictures and motion picture theaters collectively, include the silver screen and the big screen. Specific to North American term is the movies, while specific terms in the UK are the pictures, the flicks and for the facility itself the flea pit. A screening room is a small theater a private one, such as for the use of those involved in the production of motion pictures or in a large private residence; the etymology of the term "movie theater" involves the term "movie", a "shortened form of moving picture in the cinematographic sense", first used in 1896 and "theater", which originated in the "...late 14c. "open air place in ancient times for viewing spectacles and plays". The term "theater" comes from the Old French word "theatre", from the 12th century and "...directly from Latin theatrum'play-house, theater. The use of the word "theatre" to mean a "building where plays are shown" dates from the 1570s in the English language.
The earliest precursors to movies were magic lantern shows. Magic lanterns used a glass lens, a shutter and a powerful lamp to project images from glass slides onto a white wall or screen; these slides were hand-painted. The invention of the Argand lamp in the 1790s, limelight in the 1820s and the intensely bright electric arc lamp in the 1860s increased the brightness of the images; the magic lantern could project rudimentary moving images, achieved by the use of various types of mechanical slides. Two glass slides, one with the stationary part of the picture and the other with the part, to move, would be placed one on top of the other and projected together the moving slide would be hand-operated, either directly or by means of a lever or other mechanism. Chromotrope slides, which produced eye-dazzling displays of continuously cycling abstract geometrical patterns and colors, were operated by means of a small crank and pulley wheel that rotated a glass disc. Still photographs were used on after the widespread availability of photography technologies after the mid-19th century.
Magic lantern shows were given at fairs or as part of magic shows. A magic lantern show at the 1851 World's Fair caused a sensation among the audience; the next significant step towards movies was the development of an understanding of image movement. Simulations of movement date as far back as to 1828, when Paul Roget discovered the phenomenon he called "persistence of vision". Roget showed that when a series of still images are shown in front of a viewer's eye, the images merge into one registered image that appears to show movement, an optical illusion, since the image is not moving; this experience was further demonstrated through Roget's introduction of the thaumatrope, a device which spun a disk with an image on its surface at a high rate of speed. The French Lumière brothers' first film, Sortie de l'usine Lumière de Lyon, shot in 1894, is considered the first true motion picture. From 1894 to the late 1920s, movie theaters showed silent films, which were films with no synchronized recorded sound or dialogue.
OCLC Online Computer Library Center, Incorporated d/b/a OCLC is an American nonprofit cooperative organization "dedicated to the public purposes of furthering access to the world's information and reducing information costs". It was founded in 1967 as the Ohio College Library Center. OCLC and its member libraries cooperatively produce and maintain WorldCat, the largest online public access catalog in the world. OCLC is funded by the fees that libraries have to pay for its services. OCLC maintains the Dewey Decimal Classification system. OCLC began in 1967, as the Ohio College Library Center, through a collaboration of university presidents, vice presidents, library directors who wanted to create a cooperative computerized network for libraries in the state of Ohio; the group first met on July 5, 1967 on the campus of the Ohio State University to sign the articles of incorporation for the nonprofit organization, hired Frederick G. Kilgour, a former Yale University medical school librarian, to design the shared cataloging system.
Kilgour wished to merge the latest information storage and retrieval system of the time, the computer, with the oldest, the library. The plan was to merge the catalogs of Ohio libraries electronically through a computer network and database to streamline operations, control costs, increase efficiency in library management, bringing libraries together to cooperatively keep track of the world's information in order to best serve researchers and scholars; the first library to do online cataloging through OCLC was the Alden Library at Ohio University on August 26, 1971. This was the first online cataloging by any library worldwide. Membership in OCLC is based on use of services and contribution of data. Between 1967 and 1977, OCLC membership was limited to institutions in Ohio, but in 1978, a new governance structure was established that allowed institutions from other states to join. In 2002, the governance structure was again modified to accommodate participation from outside the United States.
As OCLC expanded services in the United States outside Ohio, it relied on establishing strategic partnerships with "networks", organizations that provided training and marketing services. By 2008, there were 15 independent United States regional service providers. OCLC networks played a key role in OCLC governance, with networks electing delegates to serve on the OCLC Members Council. During 2008, OCLC commissioned two studies to look at distribution channels. In early 2009, OCLC negotiated new contracts with the former networks and opened a centralized support center. OCLC provides bibliographic and full-text information to anyone. OCLC and its member libraries cooperatively produce and maintain WorldCat—the OCLC Online Union Catalog, the largest online public access catalog in the world. WorldCat has holding records from private libraries worldwide; the Open WorldCat program, launched in late 2003, exposed a subset of WorldCat records to Web users via popular Internet search and bookselling sites.
In October 2005, the OCLC technical staff began a wiki project, WikiD, allowing readers to add commentary and structured-field information associated with any WorldCat record. WikiD was phased out; the Online Computer Library Center acquired the trademark and copyrights associated with the Dewey Decimal Classification System when it bought Forest Press in 1988. A browser for books with their Dewey Decimal Classifications was available until July 2013; until August 2009, when it was sold to Backstage Library Works, OCLC owned a preservation microfilm and digitization operation called the OCLC Preservation Service Center, with its principal office in Bethlehem, Pennsylvania. The reference management service QuestionPoint provides libraries with tools to communicate with users; this around-the-clock reference service is provided by a cooperative of participating global libraries. Starting in 1971, OCLC produced catalog cards for members alongside its shared online catalog. OCLC commercially sells software, such as CONTENTdm for managing digital collections.
It offers the bibliographic discovery system WorldCat Discovery, which allows for library patrons to use a single search interface to access an institution's catalog, database subscriptions and more. OCLC has been conducting research for the library community for more than 30 years. In accordance with its mission, OCLC makes its research outcomes known through various publications; these publications, including journal articles, reports and presentations, are available through the organization's website. OCLC Publications – Research articles from various journals including Code4Lib Journal, OCLC Research, Reference & User Services Quarterly, College & Research Libraries News, Art Libraries Journal, National Education Association Newsletter; the most recent publications are displayed first, all archived resources, starting in 1970, are available. Membership Reports – A number of significant reports on topics ranging from virtual reference in libraries to perceptions about library funding. Newsletters – Current and archived newsletters for the library and archive community.
Presentations – Presentations from both guest speakers and OCLC research from conferences and other events. The presentations are organized into five categories: Conference presentations, Dewey presentations, Distinguished Seminar Series, Guest presentations, Research staff
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.
