The following is a list of programs featured on Noggin. The brand launched in 1999 as a joint venture between MTV Networks (owners of Nickelodeon) and Sesame Workshop. At first, the Noggin channel featured three sectors of programming: a main block aimed at pre-teens and teenagers, a morning block for preschoolers, and a "retro" block at night. In 2002, Sesame Workshop sold its stake in Noggin to Nickelodeon, but it continued to co-produce content for the brand. In the same year, Noggin discarded its retro block and extended its preschool and teen blocks to last 12 hours each per day. The older-skewing shows that made up Noggin's original tween and teen lineup aired exclusively during the teen block, now retitled "The N."
