At Google I/O, Google unveiled a major new unified messaging service for iOS and Android called Hangouts. Hangouts is a cross platform service that will replace Google Talk, Google+ Messenger  and the Google+ video chat. Earlier it was rumored to be called Babel, but Google announced it as Hangouts.

Google Hangouts will allow the sharing of photos, emoji, and video calls, together with traditional text conversations. Google also allows users to go back through the chat history, delete messages, and even retrieve files from previous conversations.
