Several years ago when Google+ launched, one of its key features was Hangouts, a video chat program that allowed several people to chat online at once. Hangouts grew so popular that it eventually spun off a public-facing option called Hangouts On Air, where would-be stars could interact with their adoring fans. Indeed, actual public figures like Tyra Banks, Brad Pitt and even the President have taken to Hangouts On Air in the past to answer queries. But come September 12th however, that option will be no longer, at least on Google+. Instead, users will be prompted to use YouTube Live, Google's other live video product, to broadcast in real-time.
