Cartoon Cartoons was a collective name for Cartoon Network original series. These cartoons were originally prouced by Hanna-Barbera and Cartoon Network Studios, but over the years, studios like a.k.a. Cartoon, Kino Films, Stretch Films, Blanky Blook and Curious Pictures produced these series for Cartoon Network. Any and all Cartoon Cartoons have been featured as a part of Cartoon Network's Friday night programming block, Cartoon Cartoon Fridays. In 2003, Cartoon Network stopped using the Cartoon Cartoon moniker for its original animation. Many original animated series that have premiered from 2003 until present have aired on the Friday night block (now called just Fridays), but are not officially called Cartoon Cartoons. Additionally, in the United Kingdom Cartoon Network, Toonami and Boomerang have late night Cartoon Cartoons programming blocks containing most of the productions made in the 1990s along with Foster's Home For Imaginary Friends.
