Nickelodeon On CBS
Nick Jr. on CBS and Nick on CBS were the brandings of a Saturday morning children's programming block on CBS that ran from September 16, 2000 through September 9, 2006. This Saturday morning block presented programming from Nickelodeon, which at the time shared common ownership with CBS under Viacom.
The block replaced CBS Kidshow, a block primarily composed of Canadian programming, upon its debut in 2000. For the first two years, Nick Jr. on CBS aired programming exclusively from Nick Jr., including interstitials from Face, the Nick Jr. mascot. On September 14, 2002, Nick Jr. on CBS was re-branded as Nick on CBS, expanding its lineup to include Nickelodeon shows not in the Nick Jr. lineup. The Nickelodeon shows were removed in 2005 in favor for a return to an exclusively-Nick Jr. block. The block's continuity was provided by segments featuring Piper O'Possum.
At the beginning of New Year's Eve 2006, Viacom was split into two different companies, with CBS Corporation becoming its own standalone company and Nickelodeon going to the new Viacom. Nick Jr. on CBS ended on September 9, 2006 and was replaced by KOL Secret Slumber Party on CBS on September 16, 2006, as part of a multi-year partnership between CBS and Cookie Jar Entertainment.
As with most Saturday morning children's blocks, all programming was E/I compliant, which was part of the reason why some of Nickelodeon's most popular programs did not see air on CBS. For example, SpongeBob SquarePants (at the time Nick's most popular show) would not air on CBS until 2012, long after the two channels had separated. (CBS aired the SpongeBob episode, It's a SpongeBob Christmas!, on November 23, 2012.) CBS also aired the SpongeBob episodes, "Christmas Who?", on Christmas 2002, "The Sponge Who Could Fly" on Earth Day 2003, "Friend or Foe" on June 15, 2007 and "WhoBob WhatPants" on Earth Day 2009.
