Introduction to the PubNub Data Stream API

PubNub Data Streams allows you to establish and maintain persistent socket connections to any device (mobile, browser, desktop, and server), and push data to global audiences in less than a 1/4 second. PubNub utilizes the Publish/Subscribe model for real-time data streaming and device signalling, supporting all the capabilities of WebSockets, SignalR, Socket.IO, WebRTC Data Channel and other streaming protocols.

PubNub Broadcast allows you to stream data to millions of users simultaneously, for use in apps like second screen, multiplayer games, and audience participation apps. PubNub Unicast is for one-to-one device signaling, for use in apps like call triggering, machine to machine, and location tracking.
