End of School Year Prompts Visits to Travel and Entertainment Sites

Yahoo! Sites Maintains Commanding Lead in Japanese Market

TOKYO, JAPAN, May 7, 2008 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released its March 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. With the past school year coming to a close in March, many people in Japan turned to the Web to prepare for the new school year and to research graduation celebrations and trips. Online gaming destinations Konami and NHN Corporation also experienced increases as spring vacation meant more time for online games.

“The end of the school year is a busy time for people in Japan, as many plan graduation celebrations or their spring breaks in March before returning to classes in April,” said Maru Sato, Managing Director of Comscore Japan. “Travel sites such as Jalan.net and Mapion.co.jp saw traffic increase as people prepared for their vacations, while restaurant navigation destination Hotpepper.jp and entertainment destination site Walkerplus.com also experienced significant gains.”
