PBS and NPR are undoubtedly the best in regards to objectivity.
From Ken Stern, former CEO of NPR:
"Most reporters and editors are liberal — a now-dated Pew Research Center poll found that liberals outnumber conservatives in the media by some 5 to 1, and that comports with my own anecdotal experience at National Public Radio. When you are liberal, and everyone else around you is as well, it is easy to fall into groupthink on what stories are important, what sources are legitimate and what the narrative of the day will be."
"This may seem like an unusual admission from someone who once ran NPR, but it is borne of recent experience."
I have a friend who worked for NPR. She felt the same way.
When I listen to NPR or watch PBS, I feel that there is large bias.
But --
I think that all news has large bias.
I think that the solution is to sample from the whole spectrum. The differences point out how each side spins its stuff, what it leaves out, how it frames issues to assign you an opinion, etc.
