Toonami (a portmanteau of the words cartoon and tsunami suggesting a "tidal wave" of animated cartoons) was a registered trademark of Cartoon Network, used initially for action-oriented programming blocks on Cartoon Network television channels worldwide, mostly showing American cartoons and Japanese anime, originating in the United States on March 17, 1997 and ended on September 20, 2008.
Rest in peace Toonami...
...Update: On May 16, 2012, Adult Swim posted a message on Facebook announcing that Toonami would return on May 26, with a similar message on Twitter, ending with #ToonamisBackBitches. The network issued a press release later that day confirming the block's revival as a Saturday late night anime block. Toonami made its return with all new bumpers and updated animation of TOM's third incarnation. The new midnight timeslot of the block has more mature themes than its predecessors. The current lineup imports Adult Swim's anime and adds two new shows, Deadman Wonderland and Casshern Sins.
