In the early days of the Google+ social network, some artists started experimenting with its Hangouts webcam feature to host intimate online gigs with fans. Google caught on, and started an initiative called Hangouts On Air designed specifically for musicians and celebrities to use, with the Black Eyed Peas one of the first big acts to use it. Now it’s expanding. “We’re turning it on for hundreds more public figures, celebrities and other Google+ users with large followings,” blogs Google’s SVP Vic Gundotra. “We’re making Hangouts On Air completely self-service, so you can broadcast whenever you’re in the mood. We’re integrating it with YouTube, so once you’re off the air, we’ll upload a full-length (and private) recording to your account.” The move should see more musical events livestreaming on Google+.
