Role of media

As we all know the politicians of our country do not show any sense of responsibility towards society. They have come to power only for their own sake. Their children study abroad. It's an old story.

My question is about the responsibility of the media. I'm a student of mass communication. From the first year we know that mass media play the role of a teacher to society. I don't want or expect that role from our media. But at least I can hope that it would accurately project the political situation in the country and the politicians responsible for it.
