You should look into watching the Nicktoons Network, or the sister station of Cartoon Network called Boomerang. Both still play cartoons pretty much all day, every day, and Boomerang plays a lot of the classics.

There's some pretty decent shows that play on Cartoon Network, I think. I'm actually a pretty huge fan of Chowder. :3 As for Adult Swim, it's been forever since I felt the urge to tune into anything they have playing, the exception being The Venture Bros.

I'm not particularly upset, because like I stated earlier, there's alternatives to be enjoyed, but yeah, it's kind of weird seeing some of these shows being passed on to the youth as being "quality" animated programs. Chowder is awesome though.
