"A Hangout is a web-based tool created by Google for communicating through video. Up to ten people can "hang out" at one time in a virtual "room." A Hangout can be as simple or as complex as needed for the task at hand. It can be used simply to converse or, through the use of extra apps and add-ons that Google provides, a Hangout can become a robust, virtual meeting space.
"Who Can Start One?
"One of the best aspects of Google Hangouts is that all you need is a Google Plus account to start one. If you already use Gmail, that means you already have a Google account, and all you would need to do is set up your Google Plus account. Anyone you want to talk to also needs to have a Google account and a Google Plus account set up. Once those first steps are out of the way, all you have to do is click "Start a Hangout," invite some people and begin your live video conference! For more information, watch this simple overview of starting a Hangout."
