It's no coincidence that Comic Books and Video Games have gone hand in hand. A long time ago there used to be quite a number of comics that targeted young kids, girls and people other than the 11-15 year old male demographic. There's also been lots of effort put into making games that will appeal to people outside of that demographic.
You could say, numbers don't lie, that those titles weren't being sold in enough quantities to keep them alive...and in some sense that's true. But how many ultra-niche comics with bizarre indie storylines stay alive year after year?
Actually a very large number of women I know ended up just reading Manga, they managed to find storylines and characterizations that they enjoyed. And now those women are watching cartoons, movies and dramas based on those same Manga. Most comic book stores you go into have a Manga section these days. But Manga is also full of titles with lots of sexualization. Like anything you have to be a smart consumer and not write off an entire class of entertainment, like movies, just because adult film stores exist.
It's the same with video games, after decades of struggle to find the market, some surveys are showing that women make up a significant portion of computer-game players: with leading games like The Sims, Bejeweled and WoW having huge populations of women playing them.
So the market is there, it's just that the makers are not doing a good enough job of hitting that market. Console game makers are just now starting to learn from computer game makers, and we're starting to see decent titles (mostly PC ports) to woo the other 50% of the market. But they too have really put out some crap trying to find that market.
But here's the truth, the women in mainstream super hero comic books are barely anatomically correct, but so are the men. Average characters possess exaggerated musculature not even the Greek gods possessed. And everybody has fantastical powers. These aren't meant to be forms of entertainment that represent reality...even a little bit. They're meant to be highly exaggerated depictions of reality, but the vector of exaggeration is very obviously on stereotypical male vectors.
