media and its role

It is all right to be an advocate of an independent media, devoid of any kind of control other than the market.But is it just sufficient for the media to be free and independent?.I think media also has a social responsibility and should not just pander to the market forces.Because the market is not just a monolithic entity. There are various sections and each with a separate and distinct thought process and the media should be able to mirror all these thought processes.And after all is the media all that free for many a times we get an impression that sections of the media are dancing to the tune various vested interests. And being driven by the market should not seem like being by monetary considerations
