When the Saturday night block debuted on February 23, 2002, it was known as "Adult Swim Action", with various anime programs displayed on the block from 11:00 pm to 2:00 am ET. Thus, programming on the block was divided between "Adult Swim Action" and "Adult Swim Comedy". "Adult Swim Comedy" was Sunday nights and ran from 10:00 pm to 1:00 am ET. Two days prior, on February 21, Adult Swim stopped airing on Thursday nights. "The Rocky and Bullwinkle Show" and "The Popeye Show" took "Cowboy Bebop"s place for 12:00 am and 12:30 am ET. On June 15, 2002, Adult Swim had their first contest called "Adult Swim Happiness Sweepstakes" where winners could win a Master Shake air freshener.
