The DC Animated Universe (DCAU; also referred to as the Timmverse or Diniverse by fans) is a shared universe of superhero-based animated television series, produced by Warner Bros. Animation and based on characters that appear in American comic books published by DC Comics. The shared universe, much like the original DC Universe in comic books, was established by crossing over common plot elements, settings, cast, and characters. The first TV series set in the DCAU was Batman: The Animated Series, which premiered in 1992; the last TV series was Justice League Unlimited, which ended its run in 2006. The associated media franchise also includes direct-to-video feature films and shorts, comic books, video games and other multimedia adaptations set in the same continuity.
