Video ad platforms BrightRoll and TubeMogul agreed to participate in the final technical trial of Nielsen’s mobile ad measurement tool. The partnership is part of Nielsen’s effort to expand Nielsen Online Campaign Ratings, which measures the audience of digital advertising, Nielsen said in a news release (http://bit.ly/1lcSNWt). The expansion includes audience measurement through mobile devices, it said. With the addition of mobile, Nielsen Campaign Ratings will be a measurement suite offering robust insight into a campaign’s full digital and cross-platform audience, Nielsen said.
