The changes we’ve seen at DMEXCO over the years reflect the maturation of the digital advertising market says Michael Rubenstein, president of AppNexus, a Xandr Company. While once startups like AppNexus would’ve had “a table with a coffee machine” for a booth, now they have huge presences as they’re backed by some of the world’s biggest companies, who are betting their businesses on digital advertising. In this interview, Rubenstein also discusses Xandr’s place in the digital advertising ecosystem, and the evolution of advanced television. Filmed at DMEXCO 2019 in Cologne.
