A little bit from column-A, a little bit from column-B.
Although the comic industry has been in decline long before the greater actual print industry.
Comic shops have been closing in my area like crazy for the past decade. Now I have one of those alternative, hipster stores Newbury Comics which survives because only 5% of it is a comic store (and usually just mainstream Marvel and DC stuff) with the rest of the store selling college posters, shirts with *****y sayings, magazines, DVDs and music. Or I can drive 30 minutes to the nearest New England comics store. In any event, I rarely shop for comics these days because it's such a hassle. Just order TPBs online, so I'm probably part of the problem. This is nonetheless a sad story.
I think superheroes will endure the next generation, but I'm afraid it will be mostly within the realm of movies and online digital comics. I could see DC and Marvel going completely under within the next two decades or so if things don't turn around.
