Honestly it's funny looking back on how angry children's media producers were at the 90s anime boom. Just look at Cartoon Network around the mid-90s. Pretty much every popular original cartoon on the network did their own DBZ parody. Oh, and the only reason Powerpuff Girls was picked up was to combat the success of anime, and make a "DBZ for girls"; it was even marketed as such

tl;dr, Japan stays winning
