Nick Jr. is an American pay television channel run by the Nickelodeon Group, a unit of the ViacomCBS Domestic Media Networks division of ViacomCBS, the channel’s ultimate owner headquartered in New York City. It launched on September 28, 2009 as a spin-off of Nickelodeon’s long-running preschool programming block of the same name, which had aired since 1988. The channel, which is aimed at children aged 2-6, features a mix of originally-produced programming, and series previously and concurrently aired on the Nick Jr. block and its previous iterations. Some of Nick Jr. ‘s programming includes series such as Blue’s Clues, Blue’s Clues and You!, Blue’s Room, Dora the Explorer, Corn & Peg, PAW Patrol, Peppa Pig, Bubble Guppies, Wonder Pets, Team Umizoomi, Wow! Wow! Wubbzy!, Blaze and the Monster Machines, Shimmer and Shine, Ryan’s Mystery Playdate, and The Backyardigans. Due to the Nickelodeon block, Nick Jr. is sometimes disclaimed on air as “the Nick Jr. channel” to avoid confusion, especially at times of day where both Nickelodeon and Nick Jr. are carrying preschool programming.
