Cookie Jar TV is a former three-hour children's programming block on CBS. It launched on September 16, 2006 as the KOL Secret Slumber Party, the block was rebranded as KEWLopolis on September 15, 2007 and again as Cookie Jar TV on September 19, 2009. The block replaced Nick Jr. on CBS/Nick on CBS, which was programmed by Viacom's Nickelodeon before the December 2006 separation of CBS and Viacom into two separate companies. The block is owned and programmed by DHX Media. As KEWLopolis, the block was a tie-in with the now-defunct monthly teen magazine KEWL, which was established in part by DiC in May 2007. Cookie Jar TV ended on September 21, 2013 and was replaced by a Litton Entertainment-produced block called the "CBS Dream Team" on September 28, 2013.
