Sound discovery platform can officially be used as a "TV companion app".
Of course, the sound discovery firm started off as a music-focused service for tone-deaf consumers, providing details when they didn't have the foggiest who was singing or what the title was.
That's changed in recent months, which has likely helped the surge in usage, with Shazam's tech adapted for TV screens to detect ads for movies, shows, and also live events like the Super Bowl and Winter X Games.
In addition to the 250m strong user base, the company says Shazam for TV in the US will now support any TV show on any channel at any time.
Eyeing the second-screen market, Shazam asserts it is a "TV companion app" that will offer cast info, photos, gossip, trivia, and built-in access to social media.
What's more, those using the Shazam Friends function will find the social integration tightened up with users able to see what shows Facebook friends have tagged, with the option to like or leave comments, which may tread on the toes of zeebox.
Andrew Fisher, CEO, Shazam, said: "According to industry studies, 86 per cent of smartphone owners use their mobile device while watching TV and, with our expansion into television, we’ve seen a surge of activity.
"We think that broadening our television service and offering more comprehensive social features will continue to drive activity and engagement."
