Toonami is an animated programming block geared towards action-oriented programming, primarily consisting of Americananimation and Japaneseanime. Originally an afternoon and evening block on Cartoon Network, it is now a late night animation block on Adult Swim. It was created by Sean Akins and Jason DeMarco and produced by Williams Street. The name is a portmanteau of the words "cartoon" and "tsunami", suggesting a "tidal wave" of animated shows.
