Herman argue that rather than acting as an independent watchdog of democracy, the media serves to mobilize public support for the special interests that dominate government and the private sector. The authors demonstrate this through a structural analysis of the media's institutional constraints and a series of comparative case studies, such as the reporting of 'worthy' versus 'unworthy' victims in international conflicts.
An analytical framework consisting of five 'filters' that news must pass through, which collectively screen out dissenting views: 1) Size and Ownership, 2) Advertising as Revenue, 3) Reliance on Elite Sourcing, 4) Flak (disciplining mechanisms), and 5) Anti-Communism (later updated to the 'War on Terror' or other state enemies) (Sources: Wikipedia, libcom.org).
The authors compare media coverage of victims of 'enemy' states (worthy) with victims of the U.S. or its allies (unworthy). For example, the murder of a Polish priest by state agents received significantly more sympathetic and sustained coverage than the murder of four American churchwomen by U.S.-backed forces in El Salvador (Sources: TheGeoPolity, Shortform).
The book argues that media bias is not the result of a conscious conspiracy but rather a 'guided market system' where journalists internalize the priorities of their employers and advertisers to survive in a corporate environment (Source: guillaumenicaise.com).
