The must flat straight answer I got. it maybe true, but it seems that for the rest of the world that if your comic has certain themes in it, layout, or art style, it's mange. or at least manga esque.
when a brand becomes very distinctive it becomes synonymous whit a product, like "band aid".
I think in "manga/anime" the opposite happened. all the types of comics/cartoons in japan that have very distinctive look and feel to them became the brand "manga/anime"
