So Dean, when did any station use forged documents to try to bring down Kerry?
But you probably wont listen. Just to your echo chamber.
Ok, you needed one anyway!
That is not my point. Before the Internet and Talk Radio (circa 1988), all we had was the liberal side of media. Now we do have both, so people can listen/read to both sides (my top 2 sites are CNN and Fox) and decide for themselves.
Given that the Liberal side is the long entrenched and established side, that is what is referred to as MSM. And many of them stil deny the emergence of the other medium.
