Twitter will be more visible than ever on Super Bowl day, with half of all ads during the game including Twitter hashtags. "That's up from just a handful of hash tags in Super Bowl ads last year, and from just one hash tag in Super Bowl ads 2 years ago," writes Julie Boorstin. In fact, "the Super Bowl will be a cash cow for Twitter," with the social network offering advertisers "promoted tweets... around the game to ensure that people watching and talking about the game are also seeing [advertisers]' message[s] on the second screen."
