Old man Rupert Murdoch has been out of the picture for a while now and turned his News Corp empire over to his two sons.
Most of News Corp's holdings around the world are liberal. Fox News was conservative because of a business decision to offer something different to the American market, and it paid off. But Murdoch's sons are themselves more liberal than their dad, and can't stand Fox News' conservative slant.
Imagine what you would do if you were suddenly given full control over CNN. Well, Murdoch's sons feel just the opposite about FNC.
I had heard the more liberal son quit and the other sons views were more in line with his fathers. It was recent as in weeks, so I hope they change course soon.
