Shazam, which these days styles itself a “media engagement company”, has revealed that people round the world have used the Shazam service to identify songs and experience more with TV shows and ads over 5bn times. P!nk’s new song Blow Me One Last Kiss marked the 5 billionth tag.

Shazam started out as a music discovery service, but has recently branched out into television, enabling TV viewers to engage with TV shows and ads for additional content and exclusive offers.

Since the launch of the Shazam for TV service last year, the company has run over 100 campaigns for global brands including Pepsi, Sony, Toyota, and several Procter and Gamble brands. Shazam has also developed partnerships with broadcasters to create dozens of custom interactive second-screen experiences for leading shows and major live events, including the Super Bowl, GRAMMY Awards, Billboard Music Awards, MTV Movie Awards, American Idol and the 2012 London Olympics.

Currently, Shazam users in the US can use the app anytime while watching the Olympics across NBC Universal properties – NBC, NBC Sports Network, MSNBC, Bravo and CNBC – to bring together in one place a blend of social features and rich content, including information on the athletes; up-to-the-minute results; video highlights; the medal count; the latest tweets from athletes; and the music during the broadcast.

“Shazam is achieving growth and customer engagement that is unparalleled, with more than 2m people downloading the app each week and using it 10m times every day,” says Shazam CEO, Andrew Fisher. “We have invested in our technology and developed strong partnerships with broadcasters, brands, artists and music labels to provide our fans with the most innovative way to discover, explore and share the content that interests them most. It took Shazam 10 years to see its first billion tags, then 10 months to achieve the second billion. And in just a year, we have gone from 2bn tags to 5bn.”

The Shazam app is available as a free download for “every major platform”.
