Jay Leno takes it on the chin from NBC when the network informs him his future as Tonight Show host has a looming shelf life. He needs to hand the keys to Conan O’Brien, who doesn’t want to be stuck in the 12:30 slot forever. As Letterman’s ratings at CBS decline, NBC makes a bizarre decision to keep its hosts happy and in the family. It’s a decision that backfires in every possible way. The fallout will spark the last, devastating shake up in the late night wars, as the battlefield goes through radical changes. Technology and taste never sleep, and the networks—and the hosts—are forced to redefine themselves as the industry moves toward the future.
