One thing Americans seem to do is jump to blame the industry. If you're fat, it must be the fast food industry's fault. Industries evolve for one reason and one reason only: demand. If we wake up tomorrow and everyone hates porn and has sex through a hole in the bed sheet, there would be a lot of porn execs looking for jobs (or releasing porn of bed sheet sex).
One issue I'm thinking of while following the thread is "what came first?"
Like any other business, to a certain extent the consumer has to drive the progression of the merchandise. New and increasingly more "interesting" pornography gets developed because the consumer base is showing that they get bored and move on.
The case might be made that it's the pornographer's fault or the consumer's fault, depending on your position about porn in general. Hard to say really.
The increased exposure and availability via internet must increase the need for new avenues of stimulation, but if there weren't enough eyeballs longing for the content it would not be produced -- it's a business.
If I produced some male-dominant woman-degrading content and lost half my members, you can bet I would be rethinking that angle.
My question is, can we really blame the industry?
