The replacement of facts by inaccuracies or intentional untruths in news coverage is an example of how vulnerable the public is to the media. Other distortions occur by the use of stereotypes and perjorative adjectives in slanted interpretations; by the dilution of news coverage of significant events with irrelevant matters; by the invention of falsely described comprehensive reporting on a subject where there is incomplete knowledge; and by a number of other practices ranging from silence to useless information. Distortion affects the contents of all media and all messages, not just the news. It affects more than contents as well, for example: frequency, timing and continuity. In unscrupulous private or public control, the media is a tool for domination, as there are few regulations preventing distortion.
