Liberal pluralism media theory argues that: 1) The media acts as the "fourth estate" in society, alongside the government, legal system, and church, by keeping the public informed on political issues and holding powerful institutions accountable. 2) Unlike Marxist views that see the media as a tool for class domination, pluralists believe the media responds to audience demands in a free market and serves an important democratic role in society. 3) The government has some power to address market failures and ensure a diversity of viewpoints, such as through public media like the BBC, but pluralists largely believe the media should be free to express itself.
