Toonami Reactor

On April 30, 2001, Cartoon Network launched Toonami Reactor, their first online streaming video service. The three-month service featured streaming episodes from Dragon Ball Z and Star Blazers, the latter of which was an online-exclusive series that never appeared on Toonami. Editorial content was provided by the now-defunct Animerica Magazine, published by VIZ Media. After the three-month "trial run" was over, Cartoon Network took it offline and completely revamped it.

On November 14, 2001, Cartoon Network relaunched Toonami Reactor with all online-exclusive programs such as Star Blazers, The Harlock Saga, and Record of Lodoss War as well as videos from Daft Punk and Toonami-themed games. Patlabor was added on February 18, 2002. In the summer of 2002, Toonami Reactor was revamped again under the Adult Swim aegis and, with a joint venture with VIZ's Weekly Shonen Jump, programmed it as "Adult Swim Pipeline."
