This document provides examples of how WebRTC is being used in real world applications. It describes uses such as connecting with a paint color consultant through live video, controlling HTML5 slides with a webcam, interacting around books and games, file transfer on Facebook, controlling an AR drone with video, using a telemedicine cart for remote communication, a guitar tuner application, connecting and collaborating remotely through Fluke Connect, scheduling live video sessions with language interpreters, hosting live video rap battles, an app to help blind users with live video calls, and controlling a telepresence robot with an iPad for remote video conversations. It concludes by asking what the reader will build using WebRTC.
