Doctor strange,ant-man and gotg were in cartoons and i think video game in the past before the movies.So there were some who do not read comics or normally do not read comics who knew about these characters before the live action movie.
Well there is a difference. I am not talking about Cruz having no name recognition in that sense. Its problem more in they are competing versions floating around and quite a few of them look visibly different. Much more so then the difference between Barry and Wally. That doesn't apply to GOTG, DOC Strange or Ant-man who were total zeroes.
So cartoons and video games do help more when it comes to more mainstream exposure more so then comics.Of comics did help with some exposure with these characters but not as much as tv and movies or games.
