The news is determined, not by the demand of the consumer, but by the advertiser. That is why they are spending hours and hours harping on what Bill Cosby is accused of doing thirty years ago, and of course, the dysfunctional Kardassian Clan.
This is true for all the networks other than NPR, BBC, and perhaps Al Jazeera.
A true picture of the total reality is simply impossible. There are six billion people on this planet. All news must select some stories and ignore others.
The US is perhaps 5% of the world's population, but stories about Americans are at least 50%, and occasionally 100% of all that is broadcast.
Bill Cosby's sex life in the 1970's and Hillary Clinton not driving a car, for example, are essentially worthless news. No one can prosecute Cosby and only some idiot addict of Fox "News" thinks that Hillary driving is even remotely worthy of mention.
