Social media scores with Super Bowl

They let their fingers do the talking.

They did it while Beyoncé mesmerized the audience during halftime at the Super Bowl. They did it during the partial power outage at the Superdome. Users of social media — mostly on mobile devices — generated a record-setting number of posts, “likes,” check-ins, mentions and comments about the big game, say two firms that monitor social-media activity.

Social-media interactions on Sunday night set a record for a Super Bowl — and for any major televised event, according to New York-based Trendrr, which followed social-media activity related to the big game on Twitter, public Facebook profiles and the social applications GetGlue and Viggle.

In all, there were 47.67 million instances of social-media engagement during the game between the winning Baltimore Ravens and San Francisco 49ers, Trendrr reports.

Last year, the Super Bowl scored 17.4 million interactions on social media vs. 3.1 million in 2011, according to Trendrr.

Even other major events pale compared with Sunday night. The April 2011 royal wedding between Prince William and Kate Middleton racked up 5.6 million instances of social-media activity, while last year’s Grammy Awards generated 17.1 million, according to Trendrr.
