This page will list series that I own and that I've seen.
Western Animation
My Little Pony: Friendship is Magic - Season 1-3. Waiting for Season 4 to be released on DVD but watched it online.
Avatar: The Last Airbender
Teen Titans - some, a couple seasons?
Freakazoid - a few episodes
Pinky and the Brain - fair number of episodes, maybe 20-30
Animaniacs - a few episodes
Live Actors
It's worth noting that I've had no television service for most of my life (and currently have none that I'm aware of), so my collection here is smaller than it might seem - I've made up for it with foreign cartoons.
Genie From Down Under
Andromeda - roughly third season
White Collar - roughly second season
Babylon 5 - should have stopped after season 4 ended. Stopped after season 5 episode 7's sex scene, will not return to the series.
Charmed (first 3 seasons? Prue thing was recent to me)
