The success of "The Simpsons" led Fox to develop other animated series aimed at adults, including "Bob's Burgers", "King of the Hill" (created by Mike Judge), "Futurama" (also by Groening), "Family Guy", "American Dad!" and "The Cleveland Show" (all created by Seth MacFarlane). "King of the Hill" was an instant success, running 13 seasons. Both "Futurama" and "Family Guy" were cancelled by the network; after strong DVD sales and ratings in re-runs, both returned to the air—"Family Guy" on Fox, and "Futurama" on Comedy Central.
