The role of the media corporations in the US is similar to that of repressive state regimes elsewhere: they decide what the public will and won't be allowed to hear, and either punish or recruit the social deviants who insist on telling a different story. The journalists they employ do what almost all journalists working under repressive regimes do: they internalise the demands of the censor, and understand, before anyone has told them, what is permissible and what is not.
