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 ( ) 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 Canada-based Cookie Jar Entertainment and subsequently by DHX Media (both of which thereby assumed responsibility for the lineup). The block was replaced by the CBS Dream Team block on September 28, 2013. History KOL Secret Slumber Party On January 19, 2006, two months after Viacom and CBS Corporation finalized their separation into two commonly controlled companies (both owned by National Amusements), CBS announced that it would enter into a three-year programming partnership with DIC Entertainment to produce a new Saturday morning children's programming block including new and older series from its program library and included the distribution of select tape delayed Formula One auto races. DIC originally announced that the block would be named CBS's Saturday Morning Secret Slumber Party; however, it was later renamed as the KOL Secret Slumber Party after DIC partnered with KOL, an AOL website aimed at children, to co-produce the block's programming. AOL managed the programming block's website and produced public service announcements which aired both on television and online. This association, along with the fact that some CBS stations chose to tape delay some of the programs to air on Sunday mornings, was what led to the block's renaming. Notably, despite AOL at the time being a sister company to Warner Bros., with whom CBS co-owned the then new CW Network, neither Secret Slumber Party nor Kids' WB advertised each other's programs. The KOL Secret Slumber Party premiered on September 16, 2006, replacing Nick Jr. on CBS (a block programmed by Nickelodeon, CBS' former sister property under Viacom ownership). Its inaugural lineup included three first-run shows (Horseland, Cake, and Dance Revolution), one show that originally aired on the syndicated DIC Kids Network block (Trollz), and two shows from the 1990s (Madeline and Sabrina: The Animated Series). The block's de facto hosts (and in turn, from whom the Secret Slumber Party name was partly derived) were the Slumber Party Girls, a teen pop female group signed with Geffen Records (consisted of Cassie Scerbo,
