People under 35 DO NOT fukk with DC outside of Batman/Superman like that. Wolverine is a cultural icon, dummy. From the cartoons, the merchandising, the BLOCKBUSTER MOVIES (both X-Men and the movies he headlined alone), he's one of the most overexposed and beloved comic book characters. He's the symbol of the X-Men which is obviously one of the biggest comic book properties of all time. You're dumb and probably autistic if you think more people know/care about the Hulk than Wolverine at this point.
WW and to an extent the Hulk (changing because of the Avengers films) peaked in mainstream (as in out of the comic book paradigm) visibility in the 70's. Wolverine was most popular in the 80s, 90s and 00s (era of films, video games, computer games, multiple animated series, multiple comic series, theme parks etc.).
