I wouldn't mind equal representation occurring through market forces, but monopolies are inherently resistant to being broken by market forces.
It certainly appeared that since Fox came around that it was the monopoly breaker - considering its tendency to be more objective than the other three legacy tv networks.
Fox was killing those guys in viewership and going strong - then, plump. They began acting like the others more and more, hiring actors like Kelly instead of true reporters. Drumming up enough negatives to sit O'Reilly down.
Now, they are little better than the alternatives, and their credibility has tanked as a result, allowing the others to catch back up.
Too bad, I thought we had the market forces breaking that monopoly.
