Marvel Comics Sales Drop

How should DC and Marvel change their business models?–OR, how can the comics industry save itself?
It’s extraordinary that in the U.S. comics have such low circulation–I believe the highest selling monthly titles top out at around 150,000 issues a month–while in France, a far smaller nation, some of the top titles hit six million monthly sales.
DC, meanwhile, thinks Superman is damaged goods and is considering dropping him . . . while Batman, who’s just had a massive blockbuster, is hemorrhaging sales.
At a certain point, you gotta wonder if there’s just astonishingly unwise business sense at work. So: how should the American comics industry work to expand its market and become viable again?
Well personally I don’t think they can. Really they can stick with producing comics since you can’t be a comic company without them but they need to now expand their horizons like they are starting to do. Such as just milking and living off the money they get for movie deals, clothes, toys, etc. I think it’s smart that Marvel has started to make their own movies since that is extremely big now and it seems all comic book movies are becoming blockbusters. With the internet in place (since most spend time on it or just read them on it) the only way I think that they could increase their income on the comic making is to try and snag rights to turn novels or movie characters into new comic storie lines aka buy Harry Potter or Twilight and make comics of new stories about them.
