The Fox approach works with limited information viewers - their mainstay. Back when O'Reilly and Jon Stewart were having their mock debates, they threw in a lot of serious conversation. O'Reilly made the point often that Stewart was confusing commentary with news. He hasn't made that claim lately, but only because no one's engaging with them since they're such loons. But I'm sure he'd still stand by it. The problem is that the Fox NEWS Network as it's called, wants that line blurred. Devoted followers - the tiny minority of the US population that could be described as such - all go by "well, I heard it on Fox News". No, you heard it one an entertainment/commentary segment of a show that happens to be on a network that has "News" in its name. All their prime time programming is opinion. O'Reilly is selling his books and entertainment shows. Hannity says some of the stupidest and most unfounded things one will encounter. Greta ain't much better; but she at least tries to center her shows around actual interviews. Every koffee klatch sort of show is four or five Fox Babes sitting around discussing topics in the news, repeating Drudge rumors and Breitbart innuendo, and the Fox Junkies lap it up as "news".
I also recall people citing Bret Baier as a decent anchor who wasn't part of the Murdoch echo chamber. You have but to see the stuff he does on his "Special Report" to know that's nonsense and those of us who said he was showing his opinions through inflection and innuendo were correct. Just after Comey's "shocker", the Fox Babes got him on the phone and he was right on script with Hannity and their other "fair and balanced" mouthpieces.
