I'm working on a school project regarding the media and whether the news they give us has any value ( Celebrity news, Royals etc )

Personal opinions are of course allowed.

But what I really need is some sort of Media Coverage Chart, im not a native speaker so I'm afraid I might not be using the correct search terms or websites.
( I'm looking for a chart showing what x newschannel covers. For example 30% celebrity news, 25% economy problems etc )

Any help would be appreciated




As I said before, to make sure this thread doesnt grow boring, feel free to discuss about it.
