Modern day press is about selling advert space, journalistic integrity is only used to aid that endeavour where it is viable. Where it is more profitable for a lack of integrity it is done. Shock jocks sell more then the rest, so they are vetted by the board.
Tabloids sell a lot more when they have opposition to pick a fight with. And having an opposing tabloid is like giving both of them a money press.
They can rip into each other and the readers can have fun as they read their modern day equivalent of the circus. The more hyperbolic and agreeable with their already established world view the better. Its all pie in the face slapstick commentary. Who needs accountability, substance, context, critique and insight into an issue when you can reconfirm that you are right and have fun doing it.
