Adult Swim debuted on Cartoon Network 20 years ago and fans of the programming block are looking back with fond nostalgia. From Space Ghost Coast to Coast to Rick and Morty and everything in between, Adult Swim has built up a solid fan base in the past two decades since first airing. Its continued popularity is evident given the love it's been getting from fans along with those involved with Adult Swim's growth.

"20 years ago today, Adult Swim launched," tweets the block's SVP/Creative Director. "Proud to have been a part of it since day one and helped define it as a brand and identity. And a place for great, funny, weird animation, music, and comedy. Thanks to everyone who gave [adult swim] your time and attention all these years!"

"Twenty years ago today, Adult Swim launched," another tweet reads. "The late-night programming block on Cartoon Network, it has since then launched some of the most well-known and loved adult animated shows and left an impressive legacy all these years later."

"Happy 20th anniversary to adult swim! Your one stop shop for surreal comedies, surprisingly poignant stuff, FOX shows, show revivals, and anime!!! Also the bane of soccermoms everywhere!" says another tweet, including images of Moral Orel, Cowboy Bebop, Harvey Birdman: Attorney at Law, and Aqua Teen Hunger Force.

Another fan credits Adult Swim for saving shows that would have otherwise been doomed forever by tweeting, "Adult Swim turns 20 and could be one of the reasons why shows like Family Guy and Futurama was able to be brought back after getting cancelled by Fox.
