Most advertising slots for the 2009 Super Bowl that weren't sold in September are still available. That is a change from earlier in the year when NBC announced that the air time had been selling faster than usual. "We're hearing from a lot of companies," said Brian Walker, senior director of communications at NBC Sports. "This is a time to show strength and confidence in their brands in a challenging economy." Walker said NBC had a total of around 67 spots for Super Bowl XLIII and has sold about 59.
