It is interesting to look at the progression comics have taken. in the 60s and 70s there was not much violance and in the 80s we had more violance but no blood and not many deaths and then the 90s hit and we have blood everywhere and sex appeal.

NightWing check this out in the example of blood

ummm.. dunno if its suitable for very young people. (up to you mods)

still... wolverine ... soooo cool :D .

Speaking as someone who works at a comic book shop, I can say that sales have been going up fairly well ever since the Civil War story arc began. This event with Capt. America is more like the peak of a resurgence rather than a desperation ploy.

It is also worth noting most comic customers I see are 18+, so it makes sense the art work would have a mature edge. Of course comics have ratings these days too, so there is something for everybody.

Yeah well... I wouldn't say a closeup shot of a cartoon girl's almost ass is exactly mature, neither is drawing hard nipples.
