Shopping and Travel Were Top-of-Mind with U.K. Web Users

Facebook Continues Meteoric Rise

London, U.K., June 27, 2007 – Comscore (NASDAQ: SCOR), a leader in measuring the digital world, today reported the top U.K. Internet properties and the top gaining properties for May, based on its World Metrix audience measurement service. Notable findings include:

• Google maintained its place as the most-visited property in the U.K. with nearly 28 million visitors, reaching 89 percent of U.K. Web users age 15 and older. Microsoft followed with 27.4 million visitors and a reach of 87 percent.
• U.K. Web users focused on travel planning for the long weekends afforded by May’s bank holidays and for summer holidays, as evidenced by some of the top gainers, which included Priceline.com, up 17 percent from April to 3 million visitors; First Choice Holidays, up 16 percent to 2.8 million visitors; EasyGroup, up 15 percent to 3.6 million visitors; and TUI Group, up 13 percent to 4.3 million visitors.
• Britons were also interested in the weather, as temperatures rose and record-setting rain fell in May. This was illustrated by the fact that The Weather Channel was the U.K.’s fastest growing property, up 36 percent to 2.4 million U.K. visitors.
• Facebook continued its meteoric rise, up 30 percent from April to 4.8 million visitors in May, its third consecutive month of gains of 30 percent or more. Facebook has increased its visitor base by 2,123 percent from May 2006, when it garnered only 216,000 unique visitors.
• Channel 4 surged in popularity (up 31 percent to 4.4 million visitors) driven by the start of a new series of Big Brother.
• Driven by the launch of a fashion line designed by Kate Moss at its flagship Topshop store, Arcadia Group experienced an increase of 17 percent to 2.7 million visitors.
• Seasonal shopping drove traffic to several retail sites in the top gainers list, including shopping comparison group Ciao Sites, up 26 percent to 3 million visitors; Karstadt-Quelle, up 16 percent to 4.4 million visitors; Marks & Spencer, up 15 percent to 2.4 million visitors; and Play.com Sites, up 13 percent to 4.1 million visitors.
• Guardian Media Group’s strong uptick of 14 percent to 3.7 million visitors was likely driven by its recent site redesign as well as the news of Tony Blair’s departure from office.
• Of the top 20 sites, BSkyB and Bebo experienced the strongest growth from April to May, with the number of unique visitors increasing by over 17 and 13 percent, respectively.
