Another Ad Exchange Boss Leaves: Jeff Green Out at Microsoft’s AdECN

Ad exchanges–giant, automated markets for online advertising buyers and sellers–are supposed to be a huge deal. So why doesn’t anyone want to run them anymore? Last month, Google lost Michael Rubenstein, the head of its ad exchange, shortly before the ad giant formally rolled out the service to the public. Now Jeff Green, the top guy at Microsoft’s AdECN exchange, is out as well.
