Open RTB 2.5

Open RTB 2.5

Open RTB 2.5 is now the most common Open RTB protocol. RTB was born from a consortium of technology leaders from both supply and demand sides in November 2010 to develop a new API that unified the protocols and automate the trading of digital advertising. The Real-Time Bidding Project is still very much active and working to evolve OpenRTB to ensure it meets the growing needs of the supply and demand sides.
