Hangouts
Google Hangouts is an instant messaging and video chat platform integrated with Google+.
Hangouts allows users to hold conversations between two or more users and is especially helpful if you're using Google Calendars to manage your schedule.
The service can be accessed online through the Gmail or Google+ websites, or through mobile apps available for Android and iOS.
All in all, Google has offered us a great and complete messaging app, as it provides:
Text
Audio
Video
As part of Google for Work, "Google Talk" or "Google Hangouts" each provides the ability for real time communication between end-users, including one-to-one and group conversations via messaging, voice and video.
Google Talk provides an XMPP programmatic interface for customers that still require legacy connectivity.
Google Apps Domain Administrators can choose which service is enabled for the domain.
