This "left vs right" stuff is all a distraction and wrong anyway. The major media outlets definitely are not right-wing biased: just look at Washington Post, NYTimes, etc. What they are is biased towards the establishment. This was especially obvious in the recent election, with things like WaPo posting dozens of editorials trashing Bernie and extolling Hillary, and the coverage of such outlets working to get Hillary elected at all costs. Of course, this is painted as "left wing" in the US because the Democrats are associated with "left", but Hillary was the Wall Street candidate, so unless you think that "left wing" equals "in bed with big corporate finance", the media outlets aren't really left-wing, they're pro-establishment.
