3.8 million

The average price for 30 seconds of air time during the big game this year is pegged at $3.8 million. That's an 8.6 percent jump from last year's $3.5 million price tag, and almost 27 percent higher than the $3 million charged in 2011. The price for the same spot in 1967 for the inaugural Super Bowl? $42,000.
