Social networking site, Twitter, seemed to steal the show during this year’s Super Bowl Sunday. The two major Twitter Super Bowl chat groups received hundreds of Tweets every minute throughout the night. While last year’s Super Bowl ads were blogged about shortly after they aired, this year’s had millions of people instantly display their feedback in 140 characters or less (as is Twitter’s maximum character count) thus providing an accurate and live pulse of the nation (check out this very cool interactive map that displays the most popular words Tweeted during the evening and from where they were sent).

And what better way for a brand to capitalize on this massive audience than having its Super Bowl ad stars Tweet to the masses. Pepsi’s PepSuber, E-Trade’s babies, and H&R Block’s Murray were among the characters who were Tweeting on game day. This type of social networking is proving invaluable for brands because of its impact and because it’s FREE! Because Twitter is an open dialogue it has the ability to connect with consumers more personally than TV spots and having grown over 600% in the last year, it can no longer be ignored by marketers.
