The only broadcast news I ever hear on a regular basis is NPR, since that's what's on my radio every single morning.
That said, I often hear bias in there, though they are still good—just as the NYT is good, you just need to know where they are coming from, and seek some additional information.
I have a friend at NPR, actually, and he's pretty moderate-center. "Conservatives" in here would likely call him a liberal, LOL. I have another friend at the NYT. And a cousin is a reporter for Bloomberg. (wow, I know a lot of reporters, lol)
He told me he's virtually Rush Limbaugh at NPR in terms of their political spectrum (meaning a conservative Democrat would be "extreme right wing" there
). He doesn't chime in with political opinions at work for that reason.
