AFAIK, Sony only controls Columbia's movie interests. Columbia isn't nearly as large as Time Warner or Paramount and their back catalog of movies. That's also not including the monstrosity known as Disney with their movies, Miramax (among other movie interests they own), and ownership of ABC.
edit: It appears that Sony also has a pretty large stake in MGM, if they don't own them outright.
