Media bias is the bias of journalists and news producers within the mass media in the selection of events and stories that are reported and how they are covered. The term "media bias" implies a pervasive or widespread bias contravening the standards of objective journalism, rather than the perspective of an individual journalist or article. The direction and degree of media bias in various countries is widely disputed ... and no more than here in the United States of America.
Practical limitations to media neutrality include the inability of journalists to report all available stories and facts, and the requirement that selected facts be linked into a coherent narrative. Because it is impossible to report everything, selectivity is inevitable. Government influence, including overt (often in some foreign states) and covert (more likely in the USA) censorship can bias the media. Market forces that result in a biased presentation include ownership of the news source, selection of staff, preferences of intended audience, and pressure from advertisers.
