The Noggin channel launched on February 2, 1999 and closed on September 28, 2009. It started out mainly aimed at tweens and teenagers, with a few of its morning programs aimed at younger children. From April 1, 2002 onward, the channel devoted half of its schedule (6 a.m. to 6 p.m.) to preschoolers and the other half (6 p.m. to 6 a.m.) to its original older audience.
