Audio identification app company Shazam said that “the entire Superbowl experience – including the ads, the game itself and the halftime show” will incorporate Shazam for TV.

Viewers using the app will be able to access discounts, free downloads, enter sweepstakes, vote on acts, participate in polls, buy music, share content on Facebook and Twitter, and support leading charities.

Shazam said that “almost half” of the advertisers will be Shazam enabled, including Toyota (competition), Best Buy (discount voucher), Cars.com (charity donation), Pepsi (free video) and Teleflora (“secret” offer).

“As the leader in ‘second-screen’ interactive TV experiences, we’re proud that Shazam is woven into the entire broadcast so that people can discover more about the game, the halftime show and the must-see ads – all on their smartphones or tablets,” said Andrew Fisher, CEO of Shazam.
