Huh. I get the feeling I've forgotten more shows than I can remember. Just to see...
Um...I guess around 96.
Now admittedly, some of those are shows I only watched a few episodes of, and I only included anime I'd seen at least one full episode (or the whole thing, for movies and OVAs).
Not to mention I forgot some things even by those criteria (like Yugioh and World of Narue).
