Cookie Jar TV was an American children's programming block that aired on CBS, originally premiering on September 16, 2006 as the KOL Secret Slumber Party; the block was later rebranded as KEWLopolis (/ˈkuːlɔːpoʊlɪs/ KOO-law-poh-lis) on September 15, 2007 and then as Cookie Jar TV on September 19, 2009, running until September 21, 2013. It was originally programmed by DIC Entertainment, which over the course of the block's seven-year run, was acquired by Cookie Jar Entertainment and subsequently by DHX Media (both of which thereby assumed responsibility for the lineup).
