Conflict between the marketplace and the public

I think there has always been conflict between the marketplace and the needs of the public. First of all there are the stereotypes of each marketplace, like Fox is the conservative network and CNN is the more liberal network. With these images I think the marketplace is always trying to please the public, but yet the public is never pleased. Either way they think a network is too liberal or conservative. The marketplace is always trying to make things better according to what the public wants and needs. I honestly think no matter what the marketplace does, the public will never be happy with it and that the two will never really meet a happy medium. Like Graham said, I don't have much knowledge in either subject.
