The first service released under the Noggin name was a television channel, whose programming was targeted primarily at pre-teens upon its launch in 1999. Noggin shifted its target audience to preschoolers in 2002.
On February 24, 2009, Nickelodeon announced that Noggin would be replaced by the Nick Jr. channel. In 2015, Noggin was revamped as a series of subscription services featuring programs from Nickelodeon and Nelvana.
