I wouldn't characterize FNC as some sort of paragon of conservatism.
I can't link the Forbes article (I refuse to turn off my ad-blocker), but Forbes claims that there is an equal percentage of both conservative and "liberal" (think progressive) watching FNC. Why? It's obvious -- FNC is after the money, so they're going to balance their spin to favor both camps. It has nothing to do with the truth -- only the money.
FNC is every bit the legacy news media as the rest of the trash.
