Nick Jr

Nick Jr. is an American pay television channel run by ViacomCBS through its domestic networks division's Kids and Family Group. It launched on September 28, 2009, as a spin-off of Nickelodeon's long-running preschool programming block of the same name, and primarily targets children aged 2 to 7. The channel's lineup features a mix of originally-produced programming, along with series previously and concurrently aired on the Nickelodeon block and its previous iterations; because of the two entities, Nick Jr. is sometimes disclaimed on-air as "the Nick Jr. channel" to avoid confusion, especially at times of day where both services are carrying preschool programming.
