Introducing WebRTC

When the World Wide Web (WWW) was first created in the early 1990's, it was built upon a page-centric model that used HREF-based hyperlinks. In this early model of the web, browsers navigated from one page to another in order to present new content and to update their HTML-based user interfaces.

Around the year 2000, a new approach to web browsing had started to develop, and by the middle of that decade, it had become standardized as the XMLHttpRequest (XHR) API. This new XHR API enabled web developers to create web applications that didn't need to navigate to a new page to update their content or user interface. It allowed them to utilize server-based web services that provided access to structured data and snippets of pages or other content. This led to a whole new approach to the web, which is now commonly referred to as Web 2.0. The introduction of this new XHR API enabled services such as Gmail, Facebook, Twitter, and more to create a much more dynamic and social web for us.

Now the web is undergoing yet another transformation that enables individual web browsers to stream data directly to each other without the need for sending it via intermediary servers. This new form of peer-to-peer communication is built upon a new set of APIs that is being standardized by the Web Real-Time Communications Working Group available at http://www.w3.org/2011/04/webrtc/ of the World Wide Web Consortium (W3C), and a set of protocols standardized by Real-Time Communication in WEB-browsers Working Group available at http://tools.ietf.org/wg/rtcweb/ of the Internet Engineering Task Force (IETF).

Just as the introduction of the XHR API led to the Web 2.0 revolution, the introduction of the new WebRTC standards is creating a new revolution too.

It's time to say hello to the real-time web!
