Comscore Announces New Initiative For No Cost Tagging of Website Server Data with MMX 360 in Hong Kong and Taiwan

Comscore’s Unified Digital Measurement Approach Continues to Gain Industry Support

Yahoo! Sites Ranks as Top Internet Property in Hong Kong

Hong Kong, October 21, 2010 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced that it will offer free participation in MMX 360 to online publishers in Hong Kong and Taiwan. Under this new initiative any publisher can now participate in MMX 360 measurement with no implementation fee for tagging their website server data, providing publishers of all sizes the ability to participate in this enhanced, unified approach to digital measurement. Comscore also announced growing industry support of the Comscore MMX 360 measurement solution, with Discuss.com.hk and Uwants.com recently becoming the first Hong Kong-based publishers to participate in this approach.

“Comscore MMX 360 provides the most comprehensive digital measurement solution available in the industry today,” said Victor Cheng, Comscore Head of Market Development for Hong Kong. “By offering publishers in Hong Kong and Taiwan the opportunity to participate in Comscore MMX 360 tagging at no cost, we hope to provide the industry with enhanced accuracy in online measurement and continued innovation that will help bring growth to the digital economy.”

Comscore MMX 360 was launched in the Asia Pacific region earlier this year. The service combines both panel and census-based approaches for measuring digital consumer behavior to provide a more harmonized audience measurement solution, while also helping to reconcile the long-standing debate between the two measurement approaches. The enhanced methodology also accounts for a more complete view of total Internet usage, including traffic from Internet cafes and mobile devices, which are both significant originators of Web usage in this region.

“We welcome Comscore’s continued innovation in measuring the increasingly complex world of digital media consumption in Hong Kong,” said Oscar Leung, General Manager of Networld Technology Limited; owner and operator of HK's leading community websites Discuss and Uwants. “Comscore MMX 360 provides the most accurate and comprehensive view of visitors’ behavior at Discuss and Uwants sites. As one of the top destinations for users in Hong Kong, we are pleased to be one of the first local publishers to participate in this exciting innovation for the digital industry and to offer advertisers and agencies a more accurate and comprehensive view of the audience at our sites.”

“The online channel continues to be an increasingly important advertising vehicle to reach consumers across Asia,” said Kevin Huang, CEO of Pixel Media, a leading online ad sales company in HK and ad sales representative of Discuss and Uwants. “As the industry tries to bring a larger share of ad dollars online, advertisers and publishers need reliable measures to operate effectively in the growing digital economy. Comscore provides the most-trusted insights on digital media consumption and continues to deliver innovative solutions to measuring the digital landscape.”
