Retail Sites Post Second Consecutive Month of Strong Gains During Holiday Shopping Season

RESTON, VA, January 15, 2008 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released its monthly analysis of U.S. consumer activity at top online properties for December 2007 from the Comscore MMX service. The month saw increased traffic to retail sites, shipping sites, and weather sites.

“While the online holiday shopping promotions begin in earnest in November, the heaviest shopping and online spending actually occurs in December,” said Jack Flanagan, executive vice president of Comscore MMX. “With shipping date guarantees extending later and in-store pickup options available, online holiday shopping is becoming increasingly conducive to the procrastinator.”

Holiday shopping resulted in several retail categories experiencing significant growth during the month. The fragrances/cosmetics category climbed 30 percent to 21.5 million visitors, making it the top-gaining category for December, led by BathandBodyWorks.com with 4.4 million visitors (up 27 percent) and Sephora.com with 4.1 million visitors (up 41 percent).

The consumer goods category once again saw significant growth for the second consecutive month, gaining 23 percent to nearly 36 million visitors. OfficeMax led the category with 15.3 million visitors, up 170 percent from the previous month, with much of the growth generated by the popular Office Max branded viral holiday greeting siteElfYourSelf.com. OfficeMax also claimed the top-gaining property position for the month. Other consumer goods sites achieving growth included QVC Sites, up 3 percent to 6.1 million visitors, and retailer Hammacher Schlemmer’s site Hammacher.com, up 9 percent to 807,000 visitors.

The retail - music category posted a 17-percent increase to nearly 28 million visitors, led by Barnes & Noble with 9.3 million visitors (up 20 percent), CDUniverse.com with 3.5 million visitors (up 4 percent) and eMusic with 3.4 million visitors (up 89 percent).
