I noticed that Fox was on everywhere as soon as I arrived in the US as an immigrant many years ago. In the airports, in large stores, in car dealer's waiting rooms etc etc....always Fox !!! At first I just thought it was 'TV' and did not pay much attention, then it gradually became obvious which side it was promoting ! Trouble is a lot of people do not study political concepts very carefully & if they watch this stuff it is getting thru to them because it is very subtle in how it puts out the messaging !
