On June 6, 2002, comScore acquired the North American Internet audience measurement assets of Media Metrix Inc., the leading provider of such services. On June 11, 2002, Taylor Nelson Sofres (TNS), parent company of CMR, acquired the business and assets of Evaliant Media Resources LLC, a leading provider of online advertising data. Media Metrix now operates as the comScore Media Metrix division of comScore Networks; Evaliant now operates as a division of CMR/TNS.

Following these acquisitions and subsequent developments, including the recent introduction of the next-generation comScore Media Metrix 2.0 audience measurement service, comScore and CMR have elected to expand their alliance to include several important new elements.

As part of this expanded alliance, comScore Media Metrix will co-market Evaliant services to marketers across a broad range of industries. CMR will also co-market new comScore Media Metrix products, including the comScore Media Metrix 2.0 and Audience insite Measures (AiM) services. Further, CMR and comScore will collaborate to integrate comScore Media Metrix audience measurement data with CMR's Evaliant ad-tracking data to provide the convenience of uniform reporting to clients who purchase both services.

"Our partnership with comScore provides a strong foundation upon which both companies can build compelling new services and capabilities," explained David Peeler, president and CEO of CMR. "The expansion of this alliance is a natural step ahead in our efforts to offer greater value and convenience to our clients."

"It's clear that our continued integration with CMR's outstanding relationships and technology better serves advertising and media clients," noted Magid Abraham, Ph.D., president and CEO of comScore Networks. "And with the growing importance of online ad measurement across other sectors, we're delighted to offer Evaliant and other CMR products to the marketers that comScore serves, from automotive to financial services and the many diverse industries in between."
