The Fox Broadcasting Company (often shortened to FOX) is an American free-to-air television network that is a flagship property of the Fox Corporation. It is a subsidiary of the media conglomerate 21st Century Fox.

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 free-to-air 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.

The Simpsons, starting in December 1989, has gone on to be the longest running sitcom and animation shows in history.
