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.
"When personal guilt in relation to a past event becomes a continuous cloud over your life, you are locked in a mental prison. You have become your own jailer. Although you should not erase your responsibility for the past, when you make the past your jailer, you destroy your future. It is such a great moment of liberation when you learn to forgive yourself, let the burden go, and walk out into a new path of promise and possibility. Self-compassion is a wonderful gift to give yourself." ~ John O'DonahuePrevious Quote
