In the last six years, Super Bowl ads have risen in cost by over a million dollars per 30-second ad.

According to Nielsen, which provided the data for the chart above, Super Bowl ads went from about $2.3 million in 2007 to $3.1 million in 2011. According to ESPN, the ads for Sunday’s game cost an average of about $3.5 million per 30-second spot. That’s an amazing rise just in the last few years.

Some other interesting stats about America’s favorite sporting event, according to the Los Angeles Times:

Americans spent $10.8 billion on beer for the game. There were 12,233 tweets per second towards the end of the game. Twelve percent of Americans took Monday off, either via vacation day or “sick day.” Traffic to the Fiat 500 Abarth website increased by 138 percent during the game (after the ad with supermodel Natasha Poly—go figure).
