A hangout is a 10 person (9 + host) chat room that lives within the social network of Google Plus, a crowd sourcing tool. A regular Hangout is private only to those 10 people inside the Hangout. A Hangout On Air, however, streams live on your YouTube Channel and automatically records there for playback later. You don't need video capturing software, a video production switcher or another live streaming account. A Hangout is a free television station that broadcasts on YouTube.
Recently, Carra Riley, a real estate consultant in Arizona, demonstrated how a realtor could open up a Google Plus Hangout during a buyer's tour or open house. The buyer doesn't have to leave their house or their smart phone to be face to face with the property and have the ability to ask questions
about it in real time.
