Censorship is largely self-censorship, by reporters and commentators who adjust to the realities of source and media organizational requirements, and by people at higher levels within media organizations …
The mass media serve as a system for communicating messages and symbols to the general populace. It is their function to amuse, entertain, and inform, and to inculcate individuals with the values, beliefs, and codes of behavior that will integrate them into the institutional structures of the larger society. In a world of concentrated wealth and major conflicts of class interest, to fulfill this role requires systematic propaganda. In countries where the levers of power are in the hands of a state bureaucracy, the monopolistic control over the media, often supplemented by official censorship, makes it clear that the media serve the ends of a dominant elite. It is much more difficult to see a propaganda system at work where the media are private and formal censorship is absent. This is especially true where the media actively compete, periodically attack and expose corporate and governmental malfeasance, and aggressively portray themselves as spokesmen for free speech and the general community interest. What is not evident (and remains undiscussed in the media) is the limited nature of such critiques.
