Education, Career, Automotive and Real Estate Sites See Gains to Start the New Year

TOKYO, JAPAN, February 29, 2008 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released its January 2008 rankings of the largest and fastest-growing Internet properties and site categories in Japan, based on data from the Comscore World Metrix audience measurement service. January saw increased visitation to education, career, automotive and real estate sites as many people in Japan focused their Internet activity on planning for the New Year. Several news sites, including J-Cast.com, Sponichi.com, and Jiji.com, saw significant gains in January, with elections in Osaka, the Sumo wrestling tournament, and the Chinese food scandal being major topics in the news.

“The New Year marks a time when the people of Japan begin planning and looking ahead, especially to the beginning of the new school and job year in April,” said Maru Sato, Managing Director of Comscore Japan. “Real estate sites also saw gains as visitors sought housing information for both buying and selling.”
