Fox Broadcasting Company

The Fox Broadcasting Company (often shortened to Fox and stylized in all capital letters as FOX) is an American commercial terrestrial television network that is a flagship property of Fox Corporation. The network is headquartered at the Fox Broadcasting Center in New York City, with additional offices at the Fox Television Center in Los Angeles.

Launched on October 9, 1986, as a competitor to the Big Three television networks (ABC, CBS and NBC), 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 20th Century Fox, Fox's original parent company (and still its major supplier of programming, despite its acquisition by The Walt Disney Company), 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.
