It looks like that chart just assumes that the median news is neutral. This is not a valid assumption. What is "Neutral" anyway? When news sources are compared against public opinion in the USA, Fox is just a tiny bit left of center now. This should make it obvious why Fox is the most popular news channel. If Fox were really "Hyper-Partisan Right" bordering on "Most Extreme Right", then it couldn't possibly be as popular as it is.
