COMSCORE ANNOUNCES MEDIA METRIX 360: THE NEXT GENERATION OF GLOBAL DIGITAL AUDIENCE MEASUREMENT

Revolutionary ‘Panel-Centric Hybrid’ Solution Bridges Panel-Based and Web Site Server-Based Measurement

RESTON, VA, May 31, 2009 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced the introduction of MMX 360, a ‘panel-centric hybrid’ solution to digital audience measurement. The new approach combines person-level measurement from Comscore’s proprietary 2 million person global panel with Web site server metrics in order to account for 100 percent of a Web site’s audience. The new service will reconcile traffic metrics reported from client server-side and ad server data, with fully consistent, hybrid audience measures that can be used for improved planning of online media campaigns, and for evaluating the delivery of those campaigns at an unprecedented level of audience completeness and granularity.

“Comscore MMX 360 represents an innovative and elegant measurement solution to the increasingly complex digital media landscape,” said Dr. Magid Abraham, Comscore President and CEO. “The past few years have seen the rise of global Internet markets, the emergence of new distribution platforms, and a substantial increase in media fragmentation and niche audiences. Through Comscore’s ‘panel-centric hybrid’ approach to audience measurement, we are able to combine the best of both worlds of panel and server-side measurement to bring the industry a comprehensive accounting of the complete digital media universe. Furthermore, this new approach will effectively reconcile panel and server-based measurement and provide unified numbers that are fully consistent with the ad server counts used for advertising payments. In this sense, MMX 360 represents the Web’s first true measurement ‘currency.’ The Internet industry can depend on Comscore to consistently innovate and improve its services to meet the industry’s needs, and we will continue to work cooperatively and transparently with various industry organizations to enable our clients to maximize the bottom-line benefit of our innovations.”

MMX 360 will initially be implemented with July 2009 data for Canada and the U.S. that will be published in August 2009. These countries will be followed by the U.K., where August 2009 data will be published in September 2009. The new service will be introduced into other countries beginning in Q4 2009.

“Universe Report” Provides Comprehensive Audience Reporting

A newly developed Comscore “universe report” will provide visibility into the entire universe of Internet usage, including access of Web sites from mobile devices and computers outside of home and work (i.e. Internet cafes, schools, libraries, and other non-private locations). Users at these locations can account for a significant percentage of total Web site traffic, ranging from 10 percent to more than 50 percent, depending on the particular market and country. Comscore’s “universe report” will supplement the traditional home and work universe data provided by Comscore’s existing MMX service with server-side data to account for a site’s complete usage.

MMX 360 will also enable Web site-level reporting at a significantly more granular level of detail. This feature is important to many clients as the Internet becomes increasingly fragmented and marketers’ ability to reach and aggregate niche audiences grows in importance.

MMX 360 to Reconcile Panel vs. Server-Based Metrics

The new service will eliminate the long-standing confusion about the differences between internal client metrics and the publicly reported third-party audience estimates. Comscore has developed a proprietary methodology to combine stand-alone panel and server-side metrics to calculate audience reach in a manner that is not effected by distortions such as cookie deletion, cookie rejection and non-user requested traffic.

The new Comscore methodology will continue to segment audiences by demographics, geo-demographics, and more than one thousand audience segmentation variables invaluable to planning and targeting online media campaigns. It will also preserve critical audience analytics tools, including reach and frequency and custom unduplicated reach calculations on the fly.

Industry Participation Critical to Development of Hybrid Approach

Comscore’s introduction of MMX 360 represents the culmination of more than a year of working with clients to develop and implement Comscore’s panel-centric hybrid methodology. This approach has already been implemented successfully in Comscore’s Video Metrix service. Comscore’s Canadian Research Advisory Council, a 15-member consortium of clients in Canada, has also been especially important to the development of the new methodology for Web reporting.

“A culture of transparency and data integrity is necessary in our industry,” said Sharon Flynn of Astral Television Networks and chair of Comscore’s Canadian Research Advisory Council. “Astral is proud of our collaboration with Canada’s leading media companies and Comscore to help provide this groundbreaking solution.”

“This is a significant advancement in the science of online audience measurement…a historic moment,” said Tomer Strolight, President of Torstar Digital, a leading Canadian media company and owner of Toronto Star, Canada’s largest newspaper. “We applaud Comscore for undertaking this groundbreaking step. Their willingness to work with the industry in an open fashion has resulted in the beginning of a new chapter in audience measurement history. We view it as a turning point.”

Comscore clients can choose to implement hybrid measurement for their own sites by embedding beacon calls on user-requested content. Comscore has built a massive infrastructure to handle billions of beacon requests, partnering with Akamai to use their Web Application Acceleration Solutions and deliver industry-leading response times.

We are pleased that Comscore’s hybrid initiative addresses both of these needs in a manner that is grounded in a person-level panel.”

“Direct, beacon-based measurement is imperative in order to reflect the true value of ContextWeb’s page level targeting across billions of Web pages to advertisers on our ADSDAQ Exchange,” said Anand Subramanian, CEO of ContextWeb, Inc. and the ADSDAQ Exchange. “There is no other way to effectively understand our fragmented media environment.”
