Cohen (pictured) was previously president of the IAB, and replaces Randall Rothenberg, who will become the IAB’s executive chair for a two-year term.

In his new role, Cohen will lead both the IAB and its separate, affiliated global trade association IAB Tech Lab, which is led by Dennis Buchheim. 
Cohen will report to the IAB board of directors, which is chaired by Rik Van der Kooi.

Before joining the IAB earlier this year, Cohen worked as a consultant, and worked for media companies UM and Magna between 2001 and 2019.

Rothenberg said: “In less than a year as president of IAB, David Cohen has vastly increased the size of our media marketplaces, brought an unprecedented number of industry captains into our leadership councils, transformed the timeliness of our strategic initiatives, and injected new enthusiasm into our already energetic leadership team.

“The board and I felt strongly that there was no reason to wait. He should be our chief executive now.”
