Adult Swim is an American programming block of Cartoon Network that operates at night from 8:00 p.m. to 6:00 a.m., Eastern and Pacific Time. It is programmed by Williams Street Productions, a subsidiary of Turner, which also developed two other programming blocks for Cartoon Network: Toonami (which later became a block on Adult Swim in 2012) and Miguzi. The block gets its name from a phrase used by public swimming pools in the United States to label designated times when children are restricted from using the facilities in favor of adults.
