Book excerpt: What happens when the old mass media/mass marketing model collapses and the Brave New World is unprepared to replace it? In this fascinating, terrifying, instructive and often hilarious book, Bob Garfield of NPR and Ad Age, chronicles the disintegration of traditional media and marketing but also travels five continents to discover how business can survive--and thrive--in a digitally connected, Post-Media Age. He calls this the art and science of Listenomics. You should listen, too.
