Public Broadcasting experiment

Here's an article from the New York Times on the chairman of the Corporation for Public Broadcasting (who is a Republican) and his "aggressively pressing public television to correct what he and other conservatives consider liberal bias." Just for the hell of it, I thought I'd ask, when considering your own definition of bias, is there anything about this article that stands out? In the end, I guess I'm less curious about this particular article than I am about how folks delineate bias.
