Does anime and/or manga have "ages" in the same way as American comic books?
I already some changes in the mid 70s, late 90s and late 00s
Less than half as long. The original staff for MSG is even still alive and working on the franchise. Superman's creators and original staff are long dead and have been replaced many times over.
Its the only thing we've got though
or do you want to resort to astro boy???
Before Lucky Star: all anime was manly and had great plot. Widely considered works of art, had huge respect on the West. The average anime was Cowboy Bebop.
After Lucky Star: Everything is moe.
It really depends on the place
The 80s was the era in which anime was introduced as japanimation in USA through ovas, and near 2000 was when it was first shown in TV as "anime"
This however doesn't affect anime inside Japan during that era
you know... it kind of looks like the autistic shitty versions of anime Deviantart draws. maybe in 10 years autistic fanart will be a lot less autistic.
