A network that once had a large variety of awesome cartoons and at night, sitcoms. Over time being diluted by poor direction in their shows, killing off the shows that dominated their network, and filling the entire channel with sitcoms and a few cartoons that could only be enjoyed by a 5-to-11-year-old tripping on every drug this site has a definition for, which not only is likely their target demographic now, but also the majority of members on their team.

A channel that everyone who grew up in the 90s has nostaglia for. Although they claim the cartoons were better, they actually were no better than today's cartoons, and they only remember them to be better because now they are older and are biased for the shows they grew up with and see how stupid the new ones are.
