Censorship is the power exercised by the state, person or influential group to prohibit, the diffusion to a public stadium, of a news, a book, a movie or some document, through and with which an attempt can be made against the stability of the person or group, their subsistence and even directly against their existence.
Basically, the primary objective pursued through censorship will always be limit, control freedom of expression, especially in those cases in which an opinion contrary to the established order is postulated, because of course, historically it has always been from the stick of ideas where the established order is always attacked. Therefore, due to this situation, censorship is usually the most used resource by nations that observe a form of government close to what a dictatorship is, for that reason, everything that has to do with the exercise of journalism and the different forms that will adopt the art, it will be the object of attention of those organisms that in these countries have assigned the task of comptroller.
The prohibition to disseminate certain news or work can be explicit, that is, a law has been used first that protects it, or, directly, use of force, direct coercion, to prevent the thing in question is disseminated.
But be careful! Although before we said that censorship is usually a resource in those countries that are governed by an authoritarian regime, in many western democracies there are also cases of censorship.
A very common example can be the strategy of creating a collective spirit of repulsion towards a certain journalist or television or radio content so that it is ultimately society that ends up making it disappear, without the state remaining attached to the aforementioned practice.
Also, it is usually very common that, for example, advertisers are persuaded, with some threat, of a program that expresses itself contrary to the thinking that dominates power, so that in this way it loses funding and therefore is no longer profitable for the station that broadcasts it.
