For the first time in a Super Bowl, more than half of all commercials aired during the big game included a social hashtag.

According to CNN, 57% of the ads featured hashtags, up from 50% last year and 7% the year before. Facebook got five specific mentions in ads, compared to Twitter's four.

Twitter reported that a record 24.9 million tweets about the game were sent during the telecast. That topped the 24.1 million from last year's game.

The biggest Twitter moment came when Seattle's Percy Harvin ran a kickoff back 87 yards to open the second half. That generated 381,605 tweets per minute.

That beat Twitter's peak during last year's Super Bowl, which reached 231,500 tweets per minute during the Superdome blackout of the third quarter.

Yesterday morning, 9 of the 10 top-trending terms on Facebook were Super Bowl-related.
