Nick Jr.

Nick Jr. (known on-air as the Nick Jr. Channel) is an American pay television channel spun off from Nickelodeon's long-running programming block of the same name. It is run by Paramount Global through its networks division's Kids and Family Group. The channel launched on September 28, 2009, and primarily targets preschoolers. Its lineup features a mix of originally-produced programming, along with series from the Nickelodeon weekday block; because of the two entities, Nick Jr. is known on-air as "the Nick Jr. Channel" (as of May 2018) to avoid confusion, especially at times of day where both services are carrying preschool programming.
