Google has announced Hangouts on Air, a way to live stream and record a group video conversation from different video feeds. Just a few years ago, it would have cost tens of thousands of dollars in hardware to accomplish something like this, but now it’s free and it couldn’t be simpler. The video above gives you the quick overview on how to do it. This is going to open up all sorts of possibilities for video podcasts, archive-able teaching, webinars, roundtables, world-wide meetups and lots of things that people have never even imagined because of the previous technical obstacles. I can’t wait to see what comes of it!
