Over €2 billion was spent on programmatic advertising in Europe in 2013

"At its panel at dmexco 2014 today, IAB Europe announced that it has joined forces with IHS Technology to size the programmatic market at a European level.
Recognising the growing importance of programmatic within the digital advertising ecosystem, IAB Europe sees the need to deliver greater insight on this area. This is the first such initiative by a digital advertising industry body.
The research shows that the programmatic market in Europe leaped 111% from €0.98bn in 2012 to €2.08bn in 2013.
IAB Europe and IHS Technology took a holistic approach to aggregating the data to ensure all stakeholder perspectives were included. The numbers are based on ad spend reported by IABs, transactional data, statistical and econometric models to infer a European market size and knowledge from industry experts. This programmatic research will complement the IAB Europe AdEx Benchmark report, the definitive guide to the state of the European online advertising market. Further development of research into the Programmatic market will continue to be undertaken in consultation with the IABs across Europe.
The European figure released today includes online display and mobile display to ensure all corners of the ecosystem are captured."
