Propaganda model

The propaganda model is a conceptual model in political economy advanced by Edward S. Herman and Noam Chomsky to explain how propaganda and systemic biases function in corporate mass media. The model seeks to explain how populations are manipulated and how consent for economic, social, and political policies, both foreign and domestic, is "manufactured" in the public mind due to this propaganda. The theory posits that the way in which corporate media is structured (e.g. through advertising, concentration of media ownership or government sourcing) creates an inherent conflict of interest and therefore acts as propaganda for anti-democratic elements.

First presented in their 1988 book Manufacturing Consent: The Political Economy of the Mass Media, the propaganda model views corporate media as businesses interested in the sale of a product—readers and audiences—to other businesses (advertisers) rather than the pursuit of quality journalism in service of the public. Describing the media's "societal purpose", Chomsky writes, "... the study of institutions and how they function must be scrupulously ignored, apart from fringe elements or a relatively obscure scholarly literature". The theory postulates five general classes of "filters" that determine the type of news that is presented in news media. These five classes are: ownership of the medium, the medium's funding sources, sourcing, flak, and anti-communism or "fear ideology".

The first three are generally regarded by the authors as being the most important. In versions published after the 9/11 attacks on the United States in 2001, Chomsky and Herman updated the fifth prong to instead refer to the "war on terror" and "counter-terrorism", which they state operates in much the same manner.

Although the model was based mainly on the media of the United States, Chomsky and Herman believe the theory is equally applicable to any country that shares the basic economic structure and organizing principles that the model postulates as the cause of media biases. Their assessment has been supported by a number of scholars and the propaganda role of the media has since been empirically assessed in Western Europe and Latin America.

The size and profit-seeking imperative of dominant media corporations create a bias. The authors point to how in the early nineteenth century, a radical British press had emerged that addressed the concerns of workers, but excessive stamp duties, designed to restrict newspaper ownership to the 'respectable' wealthy, began to change the face of the press. Nevertheless, there remained a degree of diversity. In post World War II Britain, radical or worker-friendly newspapers such as the Daily Herald, News Chronicle, Sunday Citizen (all since failed or absorbed into other publications), and the Daily Mirror (at least until the late 1970s) regularly published articles questioning the capitalist system. The authors posit that these earlier radical papers were not constrained by corporate ownership and therefore, were free to criticize the capitalist system.

Herman and Chomsky argue that since mainstream media outlets are currently either large corporations or part of conglomerates (e.g. Westinghouse or General Electric), the information presented to the public will be biased with respect to these interests. Such conglomerates frequently extend beyond traditional media fields and thus have extensive financial interests that may be endangered when certain information is publicized. According to this reasoning, news items that most endanger the corporate financial interests of those who own the media will face the greatest bias and censorship.

It then follows that if to maximize profit means sacrificing news objectivity, then the news sources that ultimately survive must be fundamentally biased, with regard to news in which they have a conflict of interest.

The second filter of the propaganda model is funding generated through advertising. Most newspapers have to attract advertising in order to cover the costs of production; without it, they would have to increase the price of their newspaper. There is fierce competition throughout the media to attract advertisers; a newspaper which gets less advertising than its competitors is at a serious disadvantage. Lack of success in raising advertising revenue was another factor in the demise of the 'people's newspapers' of the nineteenth and twentieth centuries.
