TOKYO, JAPAN January 28, 2008 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released its December 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.

“The holiday season is a true testament to the relationship between online and offline activity,” said Maru Sato, Managing Director of Comscore Japan. “People went online not only to shop and search for gifts, but to plan their holiday activities including Forget-Year parties and checking schedules for year-end television specials.”
