"American Dad!" also returns to the network with a four-season pickup marking a homecoming to the network for the sitcom.

Fox strikes a deal with Disney's 20th Century TV to keep The Simpsons, Family Guy, Bob's Burgers, and American Dad around for years to come.

For The Simpsons, that means the network has given the green light to Seasons 37, 38, 39, and 40; for Family Guy, the deal encompasses Seasons 24, 25, 26, and 27; and for Bob’s Burgers, it includes Seasons 16, 17, 18 and 19. American Dad! will also run for four additional seasons, starting with Season 20.
