Introduction
The Real-Time Bidding (RTB) Project, formerly known as the OpenRTB Consortium, assembled in November 2010 to develop a new API specification for companies interested in an open protocol for the automated trading of digital media across a broader range of platforms, devices, and advertising solutions.

The Open RTB API Specification Version 2.0 can be found here.

The Table of Revisions note underscores key modifications made to the document during the consultation period.
