"Adult Swim has long served as the edgier, raunchier counterpart to the kid-friendly Cartoon Network, with shows catering mainly to a teenage and adult demographic.
With its slew of bizarre, surrealist, and often graphic programming, the network has drawn 10s of millions of viewers and has pushed the boundaries of animation. Along with classics like South Park and Family Guy, it's been the main driver in popularizing adult-themed animation.
While this late-night block on Cartoon Network is still going strong, the 2000s were something of a golden era for the program. It really hit the ground running when it launched in 2001, cranking out hit after hits like Aqua Teen Hunger Force and Venture Bros., and further strengthened its lineup with existing properties like Space Ghost: Coast to Coast."
