The anime series Patalliro! ran from 1982 until 1983 and is interesting because it was based on a manga by Mineo Maya which focused on bishounen (i.e. pretty boys). The show was more comedy than anything else, but I think it's a good early example of Yaoi, which are manga focused on male gay relationships marketed to the ladies. There's a good article on the show here by Mary Kennard. It was funny for me to come across that article because back in the early 80s I knew Mary, as she could be spotted at meetings of the Cartoon/Fantasy Organization in New York City which I went to all of the time.
