Histeria! is an American animated series created by Tom Ruegger and produced by Warner Bros. Animation. Unlike other animated series produced by Warner Bros. in the 1990s, Histeria! stood out as the most explicitly educational program in order to meet FCC requirements for educational/informational content for children.
Histeria! was aired on Kids' WB from 1998 to 2000, which continued to air reruns until August 30, 2001. It was presented as a Saturday Night Live-style sketch comedy, with its cast often filling the roles of historical figures. It was to be WB's most ambitious project since Animaniacs. Like the aforementioned, 65 episodes were originally going to be made, but due to being $10 million over budget, only 52 episodes were completed before production of the series was canceled in March 2000. Due to the high production costs, footage from previous episode was often re-used and re-timed to match newly recorded audio, as well as several non-educational segments being used as filler. More recently, the show was aired on In2TV, first from March to July 2006, and then returning in October of that year. In January 2009, all of the episodes were taken off the site.
