Spider-Man: the Animated Series.
I'm also glad Huboom's got Batman and Superman on the air as well as Transformers G1 & GI Joe: A Real American Hero. I still can't believe that I remember watching CardCaptors because I don't remember a single thing that happened in it which sucks.
Stuff I'm glad I remember however include Space Ghost Coast 2 Coast, Cartoon Planet, Mike Lu & Og, Sheep in the Big City, Megas XLR, and Teen Titans...holy crap, I also remember watching The Cramp Twins on another channel.
For Disney, it's the cartoons that had Winnie the Pooh in it (particularily the New Adventures of Winnie the Pooh), Rolie Polie Olie, PB&J Otter, Buzz Lightyear of Star Command, Madeline, Pepper Ann, and Recess. I'm leaving out the more well known ones.
As for Nick, I got Rugrats, Rocket Power, SpongeBob, Doug, Ren & Stimpy, Rocko's Modern Life, Hey Arnold, the Angry Beavers, Oh Yeah Cartoons, the Wild Thornberrys, KaBlam and CatDog.
Some of the others I remember watching from other channels include the Simpsons, King of the Hill, Beavis and Butthead, and Daria.
Right now, it's Adventure Time, Gravity Falls, Regular Show, and Transformers Prime.
"I think this is bigger than black and white, I think is bigger than the police and its citizens. This is about coexistence, and if you can't coexist on your own planet, then you fight each other over...stupid. I don't get it."
