Retail-Food and Fragrance Sites See Gains Amid Valentine’s Day Celebration

Yahoo! Sites Maintains Commanding Lead in Japanese Market

TOKYO, JAPAN, March 28, 2008 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released its February 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. Valentine’s Day prompted growth in the retail-food and fragrances/cosmetics categories as women sent gifts to men to celebrate the holiday, while the government category grew as people prepared for tax season.

Mozilla was the fastest growing site in Japan, as it was in many countries around the world, due to the release of their updated Firefox browser. Traditionally February is a month when many musicians release new albums in Japan, leading several music information sites to experience increases, including Utapmap.com, Oricon.co.jp, and Sony BMG Music Entertainment. Yahoo! Sites continued their strong lead as the top web property in the Japanese market.

“Valentine’s Day has traditionally been celebrated in Japan with the women giving men gifts, especially chocolates, a practice that is slightly different from other parts of the world,” said Maru Sato, Managing Director of Comscore Japan. “As a result, traffic to retail-food sites saw a sharp increase for the month as people took advantage of the convenience of online shopping and ordering.”
