Yeah, since about 1986. I had a friend from high school who is in the comics business he was really into manga and Honk Kong films. Whenever he came home from college he would have a batch of new movies. We'd watch them and he let me borrow some.
If you're into manga, my friend does the American version of The Dirty Pair.
Very cool! I've probably seen some of his work, although I'm not heavily into manga. About the only manga I really get into is the American translation of Lone Wolf and Cub.
