Google Hangouts. Google Hangouts is a communication platform developed by Google which includes instant messaging, video chat, SMS and VOIP features. It replaces three messaging products that Google had implemented concurrently within its services, including Google Talk, Google+ Messenger (formerly: Huddle), and Hangouts, a video chat system present within Google+.
Hangouts doesn't support other chat services, so you won't be able to message someone on AIM through the Hangouts app, the way you could with Adium on a Mac. But you can message anyone with a Google account (which is basically everyone) and your message will appear on your recipient's iOS device, Android device, in Gmail, on Google+, or in their chat client if it can connect to Google.
