As of 2002, the legal position looks to have been that *"Fox (Twentieth
Century Fox Film Corporation) is the exclusive owner of all rights to the world-famous "Futurama" television series and related copyrights, trademarks, and indicia of origin"; whether or not recent deals have amended that status, I 'unno!
I'd keep it the same unless there's some new info.
