Fox Broadcasting Company, LLC (commonly known as Fox; stylized in all caps) is an American commercial broadcast television network serving as the flagship namesake property of Fox Corporation and operated through Fox Entertainment. Fox is based at Fox Corporation's corporate headquarters at 1211 Avenue of the Americas in Midtown Manhattan, New York City, and it hosts additional offices at the Fox Network Center in Los Angeles and at the Fox Media Center in Tempe, Arizona. The channel was launched by News Corporation on October 9, 1986 as a competitor to the Big Three television networks, which are the American Broadcasting Company (ABC), the Columbia Broadcasting System (CBS), and the National Broadcasting Company (NBC).
Fox has gone on to become the most successful attempt at a fourth television network; it was also the highest-rated free-to-air network in the 18–49 demographic from 2004 to 2012 and 2020 to 2021 and was the most-watched American television network in total viewership during the 2007–08 season. It is a member of the North American Broadcasters Association and the National Association of Broadcasters. Unlike other major commercial broadcast networks, Fox does not have a newscast of its own due to its lack of a news division, and instead relies on its own 24-hour news channels, Fox News, Fox Business Network, and Fox Weather to supply news programming for the network.
