Cartoon Cartoons is a collective name for Cartoon Network original series. These cartoons were produced by Hanna-Barbera and Cartoon Network Studios, with smaller studios A.K.A. Cartoon, Inc., KINOFILM Animation, Stretch Films and Curious Pictures focusing on individual projects. All Cartoon Cartoons have been featured as part of Cartoon Network's Friday night programming block, Cartoon Cartoon Fridays. During its time, the Cartoon Cartoons line spawned 15 original programs for Cartoon Network. In 2003, Cartoon Network stopped using the Cartoon Cartoon moniker for its original animation. Many original animated series that have premiered from 2003 to 2007 were aired on the Friday night block "Fridays", but these are not officially referred to as Cartoon Cartoons by the network. Additionally, in the United Kingdom Cartoon Network and Cartoon Network TOO have late night Cartoon Cartoons programming blocks containing most of the Cartoon Cartoon productions. As of 2012, the Cartoon Cartoons along with other Cartoon Network Studios shows (from the post-Cartoon Cartoons era) have been airing in reruns on the 2012 revival of Cartoon Planet, a block strictly airing Cartoon Cartoons and other original shows for the network's 20th anniversary.
