Fox Broadcasting Company, commonly referred to as the Fox Network or simply Fox (and stylized as FOX), is an American commercial broadcasting television network owned by Fox Entertainment Group, part of Rupert Murdoch’s News Corporation. Launched on October 9, 1986, Fox was the highest-rated broadcast network in the 18–49 demographic from 2004 to 2009. In the 2007–08 season, Fox became the most popular network in America in household ratings for the first time in its history, replacing CBS. CBS took back the top spot in the 2008–09 season.
The Fox Broadcasting Company and its affiliates operate many entertainment channels internationally, 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. Fox affiliate, although most of Fox’s primetime programming is subject to Canadian simultaneous substitution regulations.
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.
