LiveRamp Keeps Growing: Acquires Arbor and Circulate, Adds Tapad Device Graph

I didn’t have space earlier this week to mention Tapad’s announcement that its probabilistic device identities are now available for targeting through LiveRamp. But LiveRamp showed up again in yesterday’s news by acquiring Arbor and Circulate, which both build deterministic device identities and user profiles while selling ads on publisher Web sites. So we see that LiveRamp continues to push hard at expanding its identity resolution business.
