Your claim that NPR isn’t biased is quite frankly ludicrous. Their programming features a clear and unmistakeable liberal* bias, and the fact that you seem to be unaware of this probably just means that you share this worldview. That’s absolutely fine with me, but you should really re-examine your idea of objectivity.
* In the American sense of the word.
Edit: I acknowledge that you admit that all news organisations are biased, however I’m responding to your central claim that NPR fills the objective role referred to by GP
Here's NPR poorly representing the controversy over the Google memo this summer:

Without relitigating the whole kerfuffle, I believe that whether or not you think the media is fair to Damore depends on whether or not you are in agreement with the presuppositions he held when writing the memo.
Grading on a curve, maybe NPR did fine (I've ready Fox News accounts that read similarly), but on topic, some people (Thiel) think there's some monoculture in the media that needs disrupted.
"Reality has a well-known liberal bias."
All joking aside, I definitely acknowledge NPR's liberal bias. My main point was to "follow the money". More traditional liberal (and conservative) media outlets have funding that is much more "active" (for lack of a better term) than NPR.
Extremely ineffective lobbying would be having elbow-patched public intellectuals testifying about federal funding's benefits on the broader Hegelian dialectic.
No, I'm not.
Every news organization will have bias because every person has bias, and news organizations are made up of people. So the real choice one has to make is: what sort of bias do I want in my news?
The easiest way to identify bias is to look at where the money comes from. In the case of CPB-funded organizations yes, some of their funding is government based, so they're likely to be biased toward reporting that favors government funding for public institutions (or, in the extreme: socialism). However they also receive a significant portion of their funding from volunteer donors, so their reporting is also likely to be biased in favor of people who altruistically give without expectation of any specific ROI.
Now, if you favor small government and self-sufficient individuals who look out for #1 above all else, NPR/PBS is probably not your cup of tea.
