I asked this on the Batman forum but I decided to post it here since I consider Spiderman to be one of the few Superheroes that have become mainstream.
What is it that has made the Spiderman so successful? A bunch of people have created their own super heroes and most never reach the kind of success that someone like Superman/Batman has reached. It seems that since the beginning Spiderman just clicked with the fans (more so than with other superheroes) taking him a step above into mainstream fame and my question is what is it that gave him that status? Very few superheroes become so mainstream and famous. Off the top of my head, the three I've mentioned are the only ones that have become mainstream and I can't really say much for anyone else (and that's not too knock other superheroes but it's rare to see anyone reach the kind of status these guys have). My interest is in knowing Spiderman's success and what got him to where he is today, but you can expand to what you think it takes to create a successful superhero. (I'm measuring success by popularity here, that doesn't necessarily mean how many issues of the superhero have been sold, but rather how mainstream the superhero has become). I'm guessing that he has to hold some common ground with the other two mainstream Superheroes.
