Nearly half of the advertisers in Super Bowl 2012 are using Shazam with their advertising

"Now the company says it’s working with nearly half the advertisers at the Super Bowl, and it’s revealing a few key ones: Viewers of the Toyota ad will be able to use Shazam to enter a contest to win two free Camrys. When viewers tag the Cars.com ad, Cars.com will donate $1.00 to one of seven charities. Pepsi’s ad will feature X-Factor winner Melanie Amaro, and using Shazam on the ad will unlock an extra video. Viewers who tag the Teleflora ad will receive a special offer. And not only is Best Buy using Shazam to offer a $50 gift card to customers who buy and activate a mobile phone in 2012 — it’s actually featuring two of Shazam’s founders in its commercial."
