NBC says it has sold all the commercial airtime for the Feb. 5 game in Indianapolis and even has a waiting list of advertisers hoping to get into the game. The average cost for a 30-second spot this year is $3.5 million, with some time slots costing as much as $4 million. Seth Winter, senior vice president of NBC Sports group sales & marketing, says the last time slot was sold just after Thanksgiving. A year ago, Fox Sports said it sold the last of its advertising spots before the end of October. Slots are still available during NBC's pregame show. Watch all of last year's Super Bowl ads here.
