The Fox Network (FOX) is the American television station that aired 72 episodes of Futurama, along with the fellow animated sitcoms The Simpsons and Family Guy, from 1999-2003.
Fox cancelled Futurama after the 2002-2003 season, leading to the quote in Bender's Big Score: "You were fired two years ago! That's when we were shut down by the delivery Network!" A sign reading "Box Network" then appears, but the electricity failed, changing the sign to the "Fox Network".
