comScore, Inc. today announced the official U.S. launch of Media Metrix Multi-Platform, the next generation of digital audience measurement and media planning. Building on Media Metrix, Mobile Metrix and Video Metrix from comScore’s Audience Analytics suite, this first-of-its-kind product – originally released to clients in Beta with September 2012 data – offers unduplicated accounting of audience size and demographics that reflects today’s multi-platform digital media environment.

“We are excited to formally introduce Media Metrix Multi-Platform, a revolutionary development that combines comScore’s flagship products to accurately account for unduplicated audiences across the desktop, smartphone and tablet platforms,” said Jeff Hackett, executive vice president of comScore, in the press release. “This unified view of digital audiences not only establishes a new measurement standard for the industry, but also has the potential to unlock insights that can deliver substantial, currently unrealized value to our publisher, advertiser and agency clients.”

The Top 50 Digital Media Property Ranking: A New View of the Digital World

Multi-platform audience measurement immediately changes the established view of the digital landscape, with media properties’ audience sizes increasing, in addition to changes occurring within content category rankings. The average property within the Top 100 increased its audience size by an average of 38 percent, and 19 of those properties had incremental mobile (i.e. smartphone and tablet) audiences that extended the reach of their desktop audiences by at least 50 percent. The properties with the greatest incremental percentage gains from mobile were Groupon (223 percent), Zynga (211 percent) and Pandora (183 percent).
