Nick Jr.

Nick Jr. is an American pay television channel run by Nickelodeon Group, a unit of the MTV Networks division of Verizon Media, 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 1971. The channel, which is aimed at children under 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 Corn & Peg, PAW Patrol, Bubble Guppies, Blaze and the Monster Machines, Shimmer and Shine, and Dora and Friends: Into the City!. 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.

The channel replaced Noggin, which was relaunched as a streaming service in 2015 and acts as a separate sister brand. Noggin's programming is distinct from the Nick Jr. channel's; it mainly carried pre-teen-oriented programs at its launch,  and its 2015 streaming service features a variety of exclusive series.

The Nick Jr. channel and the Nick Jr. block continue to air as separate entities. The block currently airs weekdays on Nickelodeon from 8:00 a.m. to 2:00 p.m. ET/PT. Those hours may vary during the summer months, other school break periods and on major national holidays), having traditional commercial breaks for certain programs. As of January 2016, Nick Jr. is available to approximately 73.0 million pay television households in the United States.
