This channel shows intros from various animated series that I've own. It may also occasionally host the credits of various animated shows.
For the purposes of claiming Fair Use: all public videos are for and come with comments about the show/game, etc - discussing things from the origins to how long the series lasted to general comments about the show. The clips are designed to use as little as possible, as well as to avoid plot spoilers.
I am - or at least strive to be - a collector of animation, I studied animation and its history at university, with a strong edge toward the theatrical work of the major movie studios. Currently I am one of the editors of keyframeonline, a resource for animation; I also review animated films, etc, there.
