RESTON, VA, May 2, 2013 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced it is collaborating with BrightRoll, the largest independent video ad platform, to bring audience guarantees to BrightRoll clients via Comscore’s validated Campaign Essentials (vCE) product suite. The collaboration provides publishers, advertisers and agencies with meaningful insights into the reach, frequency, GRPs and demographic composition of audiences being exposed to digital video ad campaigns across the BrightRoll platform, and helps ensure ad dollars are being maximized.

Together we bring brand marketers the combined benefits of video ad scale and optimization that helps them achieve their marketing objectives and increase ROI.”

“As the largest independent video advertising platform, we’re seeing a digital evolution of advertisers moving toward cross-platform solutions. Over the last year, we’ve seen a three-fold increase in the number of advertisers requesting digital audience guarantees,” said Daryl McNutt, BrightRoll SVP of Research and Marketing. “Brands are beginning to buy digital video more like traditional TV and our relationship with Comscore enables us to give clients the audience validation they need.”
