Advertising and political bias in the media - The market for criticism of the market economy

Many observers of the media argue that advertiser support of the news insulates business from critical scrutiny. News organizations know better than to bite the hand that feeds them. I examine several weaknesses in this corporate advertising bias argument. Most significantly, a favorable political climate for business is a public good, so individual businesses have an incentive to Support anti-business messages that generate an audience. Transmission of messages that fail to generate sufficient demand is inefficient. In short, advertising does not create a significant political bias.
