In some parts of the world, the media are controlled by the government. This is what we usually think of when we hear the word censorship. Democratic countries, on the other hand, take pride in upholding the principle of freedom of speech.
People are free to say and write whatever they wish, with some carefully defined exceptions.
But there is another controlling power at work in a market economy the power of money. Both influence decisions about content. Readers must find the content relevant, interesting, tasteful, and entertaining or they will drop their subscription. Advertisers will cancel their accounts if they consider the content to undermine or challenge their message about the product they sell. Since cigarette advertising was banned on radio and TV in 1970, most of this money has been spent on expensive ads in the print media.
