Now Fox News, the Web, unregulated media of all kinds has soaked the American tablecloth like a spilled punch bowl. And Murrow’s war horse is now the weakest of the Remaining Three Networks that lord it over the media universe like Denmark, Latvia and the Netherlands lord it over Europe. The old network system is decimated daily with every mouse click and each surfer looking for Bill O’Reilly. The ever-widening Cheshire grin of the Bush administration at all of this is no coincidence: With the network bullhorns overwhelmed by millions of little airhorns, there’s no more Cronkite potential. In the land where Brian Williams and John Roberts are anchors, the networkocracy is done. You report, George W. Bush decides.
