This post expands on Ailime's post above, as it would apply to the media in the United States.
Here in the U.S. we have many media outlets, with the major television networks being: ABC, CBS, NBC, and FOX.
Some of our largest cities have two or more daily newspapers while most larger cities have at least one, and almost all Americans have access to the enternet.
In an ideal world the media would only report the uncensored and unbiased news, letting the people decide on their own what the truth and and consequences are. Unfortunately many editors and producers allow their personal views to bias their judgement causing their subordinates and the outlets to reflect their views and to support their political agendas. This erroneous and misleading reporting makes it extremely difficult for the voting populace to educate themselves on important issues, which is a great disservice to the journalism profession, the people, and the country.
An excellent example of this problem, is the current news reports of an African-American lady who was fired from her government job, by the Secretary of Agriculture for alleged racist comments as shown on an edited TV video clip, this firing was publicly: demanded by the NAACP, and supported by President Obama. However when the entire tape is viewed it is obvious that the opposite is true, her statements were not racist, she is not racist and she did not deserve to be fired. Subsequently the Secretary of Agriculture and President Obama have had to publicly appologize, and she has been offered a new job. Only one of the four TV Networks has completely and accurately reported on this mini crisis, while the other three have denigrated the one.
To paraphrase the famous American author, Mark Twain, Believe only half of what you see and nothing of what you read.
NAACP = National Association for the Advancement of Colored People = Spoken as the "N, double A, CP"
