@blatham,
I just know for a fact that FAUX didn't start lying yesterday. That's because I paid some attention to them over the years, since their creation in the mid-90s. They've always lied, and that's the definition of propaganda.
Some of the people interviewed by Mayer seem to think (or pretend to think) that it was a fundamentally different FAUX News 10 or 20 years ago, opinionated yet intellectually honest. They are just wrong (or lying) about it. It wasn't. And to the degree that she buys their BS, Mayer should know better.
The only difference is that now, some people, including on the right, have finally woke up and understood the problem posed by a mainstream media watched by millions who lies day in and day out... How can a democracy function if the public is constantly lied to, these people ask? That's indeed a big problem, but it's far from a new one. Bush Junior was a clear precedent of what such a democracy can deliver... And everyone at FAUX was lying his or her ass off in support of Bush, just as they do now with Trump.
