Fridays, formerly known as Cartoon Cartoon Fridays (often abbreviated as CNF or CCF), was a Cartoon Network programming block that served as the marquee night for premieres, new episodes, and re-runs of the network's original series, which included the famed Cartoon Cartoons. The block was shown weekly on Friday nights from June 11, 1999 through February 23, 2007. It was created by Steve Patrick and Christina Augustinos, with animation produced by Primal Screen.
