You got it. The Internet is killing mainstream media, so the excutives are looking to find niches to give viewers/readers a sense of belonging. Conservatives started watching Fox is such huge numbers that CNN started failing very badly. So now they know they lost the conservatives, so they aim to please the other side of the aisle. It is working to some point. Newspapers are following suit. Advertisers don't care whether newspaper content is ethical, as long as people are picking it up. People seem to pick up the newspapers that report the news the way they want to see it. It is skewing quite a bit.
