In the 1980s and 90s, NBC was a ratings powerhouse. But when its landmark shows left the air, the network’s luck ran out.

NBC fell to 4th place in 2004 and has remained largely there ever since.

Down 9% from last year, NBC’s Fall season has been a disaster. New shows have been cancelled and old shows are languishing.

NBC will air the Super Bowl and the Olympics in 2012, but the ratings relief they provide will be short-lived.

Can the Comcast front office turn NBC around, or have they bought a $13 billion dollar lemon?
