Graphic Novels are more popular now, like Inuyasha, FruitsBasket, Hitalia Axis Powers, ect. No one I personally know reads/collects regular comic books. Although there is a store nearby that sells/trades the real old comic stuff.

What killed comic books was speculation. People thought you could make a quick buck by collecting them, so the comic book companies began make millions of copies of the newer comics to meet the demand. When people went to sell their comics to get rich, they found out they were not worth anything. So, people stopped buying. That almost killed the comic books market. Of course online comics have not helped. Greed almost killed them. They are actually becoming more popular again (sales wise).
