There's been endless chatter about the weather for Sunday’s Super Bowl in East Rutherford, N.J., but there's an outside chance it won't even turn out to be the coldest Super Bowl in history. Super Bowl VI at Tulane Stadium in New Orleans was just 39 degrees at kickoff. The forecast for Super Bowl XLVIII is for temperatures in the mid- to upper-30s. But flashing back to chilly Super Bowl VI on Jan. 16, 1972, the Dallas Cowboys defeated the Miami Dolphins 24-3 to win their first Super Bowl. Hall of Fame quarterback Roger Staubach was named MVP after throwing for 119 yards and two touchdowns. The Cowboys remain the only team to ever keep their opponents out of the end zone in a Super Bowl. The game featured two Hall of Fame coaches (Tom Landry and Don Shula) and 15 future HOF players including Staubach, Mike Ditka, Bob Griese, Larry Csonka and Paul Warfield. Ella Fitzgerald, Carol Channing, Al Hirt and the U.S. Marine Corps Drill Team performed a tribute to Louis Armstrong at halftime. Perhaps most surprisingly, the average cost of a 30-second commercial during the television broadcast was $86,000. Today, according to Forbes, it costs about $134,000 per second to air an advertisement during the Super Bowl.
