I've been thinking...
about some of my favorite animes inspirations.
I noticed something when I watched t.v. land.
the "ordinary guy meets beautiful girl which later reveals her power" anime genre comes from some classics like bewitched and I dream of geanie. so I came to terms that this genre is inspired by american entertainment.
your cut on this guys...
oh and I almost forgot to mention that a topic similar to mine at animerica magazine, they have an article about the history of shoujo.
