No one is really sure but it should have started from the point when nerds have accsess to computers. First of all people pirates in media are more accurate to ninjas in media how? you ask
First of all mostly white/western people know nothing about Ninjutsu or Ninja and they decide to make up something stupid n post in the internet or make a show out of what they know about ninjas(nothing).
It use to make me mad how like spinjutsu(the art of spinningO_oWtf) in Ninjago, SuperNinjas or any other show like that when stories which really did happen about a secret agent, mercenary assassins back then in during olden day Japan would make a way better movie/tv show. The only exeption that I like is TNMT they actually use Ninjutsu
