Roger Ailes came up with the idea for Fox News in the 70s, when he was working as an image consultant for then-president Richard Nixon. From the get-go, the idea was that a TV network would be a top-down propaganda outlet that would manipulate and control voters, especially more conservative ones. "People are lazy," read a document titled "A Plan for Putting the GOP on TV News" that was presented to Nixon in 1970. "With television you just sit—watch—listen. The thinking is done for you." Even though the document was unsigned, it's widely believed to be the work of Ailes, who wanted a "pro-Administration" mouthpiece that could go around the traditional media.
The plan didn't get off the ground during the Nixon administration. It's arguable, and Ailes certainly believed, that if such a network had existed at the time, Nixon would have very well been able to survive Watergate. A Fox News would have been able to blast Republican voters with non-stop excuses that they could use to ignore the uncomfortable reality that their president was irredeemably corrupt. The proof of concept is evident: Donald Trump has survived multiple scandals that all make Watergate look like small stakes, largely because Fox is on hand to feed GOP voters all the rationalizations they need to stick by Trump's side.
