I can't really think of a time in modern pop culture history that men didn't idolize certain dudes and their image. You don't think all of those guys who were insane Beatles and Elvis fans were that way? They dressed like them, know everything there is to know about their wives, kids, what type of gear they play, etc. Maybe you could say it started with Rock N Roll and just kept going with Punk, Hip Hop etc but then when I think about people were obsessed with the cool Jazz Musician and the bad ass country singer so this certainly isn't a new thing.
