Adult Swim is a block of Cartoon Network started in 2001, beginning as a once a week block that would air adult animation, new and imported, for three hours each night. It got so popular it expanded to be a daily block which covers all of 8 PM - 5 AM on CN, and is even considered a separate channel by Nielsen. It is overall most famous for giving the cancelled Family Guy, Futurama and Home Movies enough exposure to get picked up again (with new episodes of Home Movies actually airing on AS itself). Like Cartoon Network briefly did in the late 2000s, they eventually started adding live-action, but this decision has been more warmly revived due to the popularity of such resulting shows as Tim and Eric, its spinoff Check It Out! with Dr Steve Brule and The Eric Andre Show, and unlike its present network live action still airs to this day. This in turn led to the opening of a YouTube branch, which occasionally airs on the channel itself, which has made such (in)famous videos as On Cinema at the Cinema, Too Many Cooks, Unedited Footage of a Bear and Bushworld Adventures (a mock episode of their fan favorite Rick and Morty). Adult Swim almost never uses an actual end show logo (Williams Street unofficially serving as such although not every AS original is from them), but there has been one exception.

Logo: Merely the Adult Swim logo against a black background.
Music/Sounds: A techno tune which fades out.
Availability: Only seen on the 2018 SDCC print of the Samurai Jack series finale "CI" after the Cartoon Network Studios, Williams Street and Cartoon Network logos.
Editor's Note: More effort could have been put into it, but as it was a one time use logo it is understandable.
