Web Real-Time Communication (WebRTC) is a new HTML5 standard framework that enables the sharing of video, audio, and data directly between web browsers. These capabilities open the door to a new wave of advanced web applications.
If all goes according to plan, over 50% of all web browsers will support this capability in the next three to four months.
This is the most significant step forward in web browser connectivity since 2004, when Google launched Gmail and AJAX was coined.
