So that's just a now problem and has never existed for as long as there has been media?
It has always existed - but not at the scale or concentration it does now. I think that due to the weight of it, it classifies as a new problem.
I was trying to think of a good analogy to demonstrate it. How about this.
Balance the tip of a butter knife on the palm of your hand so you can feel the weight of it. That isn't a problem. Now, I come along and put all of my weight on the knife. Same knife, same tip, same position - new problem?
You are probably more informed now if you observe and think a little more. =)
