Query: Goldberg clearly explains the media's slide

Bernard Goldberg has written a book that explains exactly why (and how) the major networks have lost viewership. The big three (Brokaw, Jennings, and Rather) are so openly blatant in their liberal bias and probably do not even understand their failings. Viewers have switched to alternate sources, such as Fox News Network, for their news and eventually it will send a wake-up call to the major network bosses. The real question is why is it taking so long? Goldberg's book is a thoughtful, not a spiteful, story of the dying of network news.
