Cartoon Network's Fridays was a programming block on Cartoon Network, and the temporary replacement of Cartoon Cartoon Fridays. It was the marquee night for new episodes and re-runs of the network's Cartoon Cartoons during September 2003. It was shown on Fridays from 7:00 P.M. to 1:00 A.M., and ran from September 5 to September 26, 2003. Not much is known about CNF, except that it was basically Summer Fridays without the "Summer" in its name. It was replaced with Fridays, a reboot of Cartoon Cartoon Fridays in live-action format.
