This whole widening their market, expanding to new potential audiences etc.. is a complete fallacy. It's the reason why all the fuss over digital comics is a waste of time, and it is one of the main problems with the industry. You know why? This new audience doesnt exist. Not in any appreciable numbers.
People know these characters exist. they go and watch them in their droves at the cinemas. They know comics exist, but they make no effort at all to go find these comics. And they dont because they dont want to read adventures of these characters. that is the fundamental fact of it all, comics are a niche medium these days that people in general just dont care about, and nothing that gets done, putting comics up on websites, making them digitally available, tieing in with the latest movie, putting Obama in the story, whatever, wont change that. People wont suddenly go, "hey, I want to go find the latest Spider-man!!" They will go, as they do now, "spider-man comics? meh, when's spiderman 4 out?"
