I'm about 3/4 of the way through reading Bernard Goldberg's Arrogance: Rescuing America from the Media Elite, and it's terrific.
By now, liberal media bias is old news, but what makes the book so good is Golberg's funny, entertaining writing style and the fact that he offers actual, common-sense solutions to the problem. And, of course, like Bias, Arrogance is an insider's account of a tilted media that doesn't seem to know it's tilted. Goldberg is no flaming conservative (in fact, he's basically liberal on all the major issues), which makes his account that much more pursuasive.
It's a great read, though it's likely that the major media outlets will ignore it as fastidiously as they did the number one best-seller Bias.
