Remember Gracenote's plans for an Automatic Content Recognition system for TV? (think: Shazam to help you work out which The Mentalist episode is on). Now it's got a name: Gracenote Entourage. It'll run on smartphones and tablets to identify movies, TV shows and music just from the audio clip. It'll then show you related programming, actor bios and, erm, relevant advertising (but hey, they've gotta make money somehow, yeah?). It'll run on mobile devices and smart TVs, although would that really be easier than pressing the "TV Guide" button on your remote? We'll leave that for you to judge.
