The other day, Cartoon Network’s Adult Swim played a little April Fool’s joke by bringing back their Toonami anime block for an evening. They caught a lot of fans off guard, by marathoning classic Toonami programming like Astro Boy, Big O, Outlaw Star, Gundam Wing and more — they even had Steve Blum return as the voice of T.O.M. the robot, going as far as reviewing Mass Effect 3. When Toonami left the air a few years back, I remember fans calling it as an end of an era, well now it looks like they might get a chance to revive it. Adult Swim is asking its fans to voice their desire via twitter with the hash tag #BringBackToonami. I can’t say I have too many fond memories of the programming block, but I do recall being pleased about their efforts to introduce classic anime to new audiences. If you’re looking to get Cartoon Network’s attention, you can either retweet the original tweet, or use the hashtag to let them know what you’d want to see more of. Frankly, I wouldn’t mind if they decided to air Star Blazers or even some Robotech.
