CEO Magid Abraham (pictured) said: “comScore’s strong third quarter results reflect increasing momentum across our business as we continue to lead the way in digital measurement and analytics.

“Our Media Metrix MP service, which delivers multi-platform audience measurement, continued its successful customer adoption with 43 additional customers subscribing to the service in the quarter. In addition, recent announcements such as VivaKi’s selection of our validated Campaign Essentials (vCE) across all of Publicis Group for its Audience on Demand, real time bidding platform, speak to vCE’s growing market position in campaign measurement and the value our suite of advertising analytics delivers for optimising advertising buys.”
