I don't think it's quite fair to compare Fox with RT. Yes, many FNC programs and talent go toe-to-toe with the the POTUS and the RNC view of the world, but there are also enough journalists there to make the distinction cloudy. Roger Ailes was smart enough to assemble an actual news operation in order to legitimize FNC to the point that it would be just above talk radio on TV. Fox News Sunday with Chris Wallace, Shepard Smith's show, and Special Report are decent news programs, even if they may lean a little bit to the right compared to competing shows on other networks. And the Fox local affiliates run good, clean news operations that are just as good as their competitors in most markets, and the national news that they pull from the Fox wire services is of quality as well.
RT, meanwhile, is just...odd. It's not like you really even get news about Russia on it. It's more of a stream of consciousness array of questionable talking heads and video and graphics montages that take on a worldview that is distinctly, unabashedly, uniformly critical of the U.S., and to a less extent, the EU. There's hardly any enterprise reporting going on at RT or rolling coverage of live breaking news. Just looking at the structure and format of their programs, I don't think there's any English language channel that is similar.
Fox certainly has its issues and point of view, but there's at least some semblance of a news operation underneath it all. I don't think the same argument can be made of RT.
That may be so, but the majority of the 'real' news programmes are basically filler between the POTUS massaging and keeping the Republican Party on side. Peak viewing is still the same propaganda being pumped out, despite the likes of O'Reilly being fired.
Fox and Friends is on a par with what RT pump out in every bulletin, bashing what they consider is the 'mainstream media' despite being the mouthpiece of the new Washington Trump elite with a tokenistic 90 second 'real' news bulletin by another piece of eye candy.
While you clearly know more about US rolling news output, I personally think the similarities between RT and FNC in regards to subliminal propaganda crossover too much.
As for the local Fox operations, no issue with that. MSNBC is similar with regards to partisan broadcasting, but it doesn't affect the network NBC News output.
