History
In 2007, Nickelodeon was experimenting with launching a preschool channel. The channel would originally be called “NickPreschool”, but then decided to use the name of its existing programming block, Nick Jr. The channel launched on July 3, 2009 airing “the best of Nickelodeon’s preschool library”. In 2017, the channel rebranded to Nickelodeon Junior to coincide with Nickelodeon rebranding and to distinguish it from the programming block on Nickelodeon of the same name. In September 2017, a sister channel that also airs preschool programming was introduced, named Noggin.
