Boxfish is one of many startups that have popped up over the last several years to help TV viewers better find shows that they’d like to watch. Now looking to extend that technology to a number of consumer electronics manufacturers, cable providers, and third-party app developers, it’s raised $7 million in new funding. By parsing information provided in the captions that are distributed with live TV broadcasts, Boxfish is able to make sense of what’s happening on hundreds of TV channels in real-time.
