Final Super Bowl Ad Slots Not Selling

CBS News reports:

Most advertising slots for the 2009 Super Bowl that weren't sold in September still haven't moved, a change from earlier in the year when NBC announced the air time had been selling faster than usual.

Super Bowl regulars like FedEx Corp., Garmin Ltd., Salesgenie.com and General Motors Corp. are sitting out this year's football championship, to be held Feb. 1 in Tampa, Fla.
