Selfinflicted censorship

Since we are watching 1984 in class, I thought it would be appropriate to adress the issue of censorship. Not censorship related to government but to the media and its influence on the information we are provided with.
We like to believe in these liberal time that censorship is something that existed in the past and perhaps in dictatorships like North Korea or communist China. Of course you have the theories of Noam Chomsky saying that media is in fact still censored, but that is not what I would like to adress. I would like to talk about another type of censorship that is more subtle but still influencal as to what information we receive through the media.
The type of censorship Im talking about is happening through the choice and viewpoint of different information related to events reported by media. A good example of what Im talking about can be shown through an article in one of the biggest newspapers in Norway where a political youth organization has decided to sue the Norwegian press association for bad coverage of the climate conference happening in Denmark. The accusation is tsating that Norwegian newspapers only wrote articles concerning the violence and arrest of 200 protestors, not mentioning the 100.000 peaceful protestants that filled the streets of Copenhagen to get their voices heard.
This is only one example of how coverage of an event can be completely focused on a minor detail. And why is this? Because the minor details contain the x-factor that is supposed to and do in fact sell newspapers or attain viewers. It seems as if catastrophe is what we want to hear about, so catastrophe they give us. It makes me wonder if Nietzche was right when claiming that humans find pleasure in other peoples suffering, because it seems as if the greatest entertainmentfactor is people being imprisoned, killed, beaten up etc. And this need for death and destruction leads to what can be called self-inflicted censorship or filtering, that leads us to, in a case like the climate conference in Copenhagen, get the details of how many people were arrested for what violent actions, rather thn what is actually going on and what can have an actual influence on our lives, more than just entertainment...
