Why did you have to post that ruddy link, every time I go to that site my eyesight goes for about 10 minutes and I almost have an epileptic fit... 
Could someone from the USA please answer me this in regard to FOX, I get the FOX channels over here on SKY, now I don't know if it's just me but do folks in the USA actually take The FOX news channel seriously (if so I would find that very worrying)... :nervous:
It's like a bunch of talentless celebrity wannabes talking absolute keech about which zlist celeb they bumped into at the weekend or the O'reily guy who gets paid far too much and is proud to have it announced at the end of his show that his clothes are supplied by some poncy fashion designer...:nervous:
Please don't tell me that this channel is taken seriously in the USA or my opinion of American popular culture will reach an all time low... 
I think you're confusing "news" and "news entertainment" or commentary if you will.
All the networks have both in order to fill air time.
Sadly, pure news that allows the viewers to analyze on their own is in short supply.
Moreso, it was decided years ago that viewers needed to be told what to think, hence the invention of the entertainment news you now see.
In addition, controversy sells, so even if every network sponsored the same beliefs from the top, they would be quick to delineate themselves from the others to maintain ratings.
