VideoSurf for iPhone and Android: Like Shazam for TV
"You know how Shazam can figure out what song is playing at the bar you’re at? VideoSurf can figure out the show that’s on TV. You just point the iPhone camera to the TV and then record it for a few seconds, And though it’s been done before and sorta unnecessary in today’s cable-riddled, DVR guide overkill world, it’s still pretty darn cool. Also, VideoSurf is more than a one trick pony, it also acts a recommendation service, connects your friends to the stuff you watch, lets you search and identifies trends on what’s hot right now."
