Toonami

Toonami was an action cartoon block on Cartoon Network. It began airing on the US Cartoon Network on March 17, 1997 as a collection of anime and American cartoons. Its name was a portmanteau of the words cartoon and tsunami, suggesting the block to be a "tidal wave of cartoons". It aired its final transmission on September 20, 2008, being cancelled after over eleven years of broadcasting, supposedly due to poor ratings.
