The Super Bowl is the most expensive 30 seconds on TV, with ad costs growing to over $3 million a spot. According to Nielsen, the costs may be worth it, as the ads are more memorable and better-liked in their effectiveness measurements:
Last year’s Super Bowl XLVI attracted 111.3 million viewers, making it the most watched U.S. telecast of all time. This level of exposure doesn’t come cheap, however, as advertisers spent an average of $3.4 million for a 30-second spot, up more than $300,000 from 2011, according to Nielsen. Ads that aired during last year’s Super Bowl were also 34 percent more memorable and 42 percent better-liked than commercials that aired just a month earlier (January 2012).
