25 Years Ago Today, Cartoon Network Premiered One of the Best Adult Swim Shows Ever (A Year Before Adult Swim Even Launched)

Back in 2000, Williams Street created a few original shows that would become the foundation for Adult Swim’s late-night programming. One of the most memorable of these was Sealab 2021, which first aired on December 21st. When Adult Swim officially launched the following year, Sealab 2021 was a key part of its initial lineup, helping to define the network’s unique style.
