Fake News has become a catch all for any media that goes against one’s established bias. In the last decade or so news media has evolved more into “infotainment” which only perpetuates and exacerbates the problem. How? By discouraging critical consumption in the name of partisan bias confirmation.
Look, there’s no media (foreign or domestic) that is utterly objective. They all have agendas. But what’s damaging is when media (and the POTUS himself) actively discourages consumers from absorbing information with a critical eye, and instead promotes the mentality that no media is accurate or approaches objectivity unless it confirms one’s partisan views. That’s where the citizenry damages itself - by refusing to adhere to that mentality, and instead blithely absorbing information passively with the binary mindset of “I agree with this, therefore it must be true/I disagree, therefore it’s fake news.”
As to the OP question, I look to multiple domestic and foreign sources of media (the latter is good for getting away from a specific bias that US partisan bickering generates). I’m not certain but I’d say NPR and BBC are the two largest sources, since that’s what I tune in to during my work commute.
