Real-time Bidding (RTB) is a way of transacting media that allows an individual ad impression to be put up for bid in real-time. This is done through a programmatic on-the-spot auction, which is similar to how financial markets operate. RTB allows for Addressable Advertising; the ability to serve ads to consumers directly based on their demographic, psychographic, or behavioral attributes.
The Real-Time Bidding (RTB) Project, formerly known as the OpenRTB Consortium, assembled technology leaders from both the Supply and Demand sides 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. At the time Programmatic had only accounted for 4% of the display advertising market. By 2017, RTB is expected to account for 29% of the digital mix (source: eMarketer March 2013). This group continues to create open industry standards that ensure all parties, buy and sell side alike, can transact RTB at scale and build future industry innovation.

With bot traffic becoming an increasing concern to both the buy and sell sides, OpenRTB 2.2 allows for all parties to be able to provide real-time feedback on ads to determine and block non-human traffic. Release highlights include:
