"Structural factors are those such as ownership and control, dependence on other major funding sources (notably, advertisers), and mutual interests and relationships between the media and those who make the news and have the power to define it and explain what it means. The propaganda model also incorporates other closely related factors such as the ability to complain about the media's treatment of news (that is, produce "flak"), to provide "experts" to confirm the official slant on the news, and to fix the basic principles and ideologies that are taken for granted by media personnel and the elite, but are often resisted by the general population.1 In our view, the same underlying power sources that own the media and fund them as advertisers, that serve as primary definers of the news, and that produce flak and proper-thinking experts, also play a key role in fixing basic principles and the dominant ideologies. We believe that what journalists do, what they see as newsworthy, and what they take for granted as premises of their work are frequently well explained by the incentives, pressures, and constraints incorporated into such a structural analysis. These structural factors that dominate media operations are not allcontrolling and do not always produce simple and homogeneous results."
