The Detroit News and The Free Press
Of course there are those who believe that is only one valid side to political discussion. (While technically there are people on both sides who believe that the other side has no valid beliefs, those who believe that only the left is valid are overwhelmingly present in the MSM, though fortunately their control is not absolute.) Normal Lear, best known for All in the Family but also the founder of People for the American Way clearly believes that the right needs to shut up and go away. He started a takeover attempt of the News because he was disturbed by its editorial policies. There was a rescue purchase and the new owners, Gannett, while still keeping the editorial policies a bit to the right, were not as conservative as the previous owners. The humorous bashing and counter-bashing of each others' editorial boards was gone.
Still things go forward and the News and the Free Press now operate on a Joint Operating Agreement where they combine some of their operations in order to cut costs and it has been largely successful.
But not successful enough.
Now they are cutting back on home delivery to 4 days a week. They are doing it because sales are way down.
There is another reason.
The Internet. Print journalism needs to find a way to survive in the new media and so far, success has been limited.
