The Fox Broadcasting Company (commonly referred to as Fox; stylized as FOX) is an American commercial broadcast television network that is owned by the Fox Entertainment Group subsidiary of 21st Century Fox. The network is headquartered at the 20th Century Fox studio lot on Pico Boulevard in the Century City section of Los Angeles, with additional major offices and production facilities at the Fox Television Center in nearby West Los Angeles and the Fox Broadcasting Center in Yorkville, Manhattan, New York. It is the third largest major television network in the world based on total revenues, assets, and international coverage.
Launched on October 9, 1986 as a competitor to the Big Three television networks, ABC, NBC and CBS, Fox went on to become the most successful attempt at a fourth television network. It was the highest-rated broadcast network in the 18–49 demographic from 2004 to 2012, and earned the position as the most-watched American television network in total viewership during the 2007–08 season.
Fox and its affiliated companies operate many entertainment channels in international markets, although these do not necessarily air the same programming as the U.S. network. Most viewers in Canada have access to at least one U.S.-based Fox affiliate, either over-the-air or through a pay television provider, although Fox's National Football League telecasts and most of its prime time programming are subject to simultaneous substitution regulations for cable and satellite providers imposed by the Canadian Radio-television and Telecommunications Commission (CRTC) to protect rights held by domestically based networks.
The network is named after sister company 20th Century Fox, and indirectly for producer William Fox, who founded one of the movie studio's predecessors, Fox Film. Fox is a member of the North American Broadcasters Association and the National Association of Broadcasters
