29 years ago today, on March 17, 1997, Toonami made its first debut on Cartoon Network. Combining the words “Cartoon” and “Tsunami” for its name, the specialized block of programming introduced many cartoon fans to anime and other classic action shows for the first time. Though Toonami has undergone many different transformations over the years, and was even cancelled for a good while, the anime block is still going strong to this day nearly 30 years later.
Toonami Debuted on Cartoon Network 29 Years Ago Today

Originally created by Sean Akins and Jason DeMarco (who has gone on to hold very important roles with Warner Bros. in the decades since), Toonami first made its debut with Cartoon Network in a much different form than what is seen today. Much like how Space Ghost Coast to Coast started out on Adult Swim by borrowing older Hanna-Barbera characters, Toonami was hosted by Moltar as he introduced the various shows. But even in this earliest era of the block, you could tell that the spirit of it was there right from the beginning. And it came on everyday.
It was something kids could watch on afternoons after school, and offered shows like Thundercats and Voltron. But it started to take its real shape a couple of years after its debut with the first introduction to T.O.M. back in 1999. Heading into the 2000s, Toonami started to fully embrace the world of anime. With T.O.M. as its new host and “curating” a special slate of programs, it not only made each of the offered shows that much more special but made it cool. Which, in turn, made anime cool.
Toonami did things smart with its selected programming. It wasn’t the first block in the United States to offer anime shows (as they had been a staple of Saturday mornings long before), but the tone of the block made it seem like an exclusive club for the kids tuning in. Taking things in a more mature direction later with things like the “Midnight Run” variant that aired later in the evening (and offered more adult oriented shows like Outlaw Star and The Big O), it just all oozed cool.
