Social Networking Sites Account for More than 20 Percent of All U.S. Online Display Ad Impressions, According to Comscore Ad Metrix

MySpace and Facebook Each Represent Nearly 10 Percent of Total U.S. Online Display Ads Delivered

RESTON, VA, September 1, 2009 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world today released a study of U.S. online display advertising on social networking sites in June 2009, based on data from the Comscore Ad Metrix service. The study showed that social networking sites accounted for more than 20 percent of all display ads viewed online, with MySpace and Facebook combining to deliver more than 80 percent of ads among sites in the social networking category.

“Over the past few years, social networking has become one of the most popular online activities, accounting for a significant portion of the time Internet users spend online and the pages they consume,” said Jeff Hackett, Comscore senior vice president. “Social networking sites now account for one out of every five ads people view online. Because the top social media sites can deliver high reach and frequency against target segments at a low cost, it appears that some advertisers are eager to use social networking sites as a new advertising delivery vehicle.”

AT&T Top Display Advertiser on Social Networking Sites in June

AT&T ranked as the top display advertiser on social networking sites in June with more than 2 billion ad impressions, which accounted for 30 percent of the company’s total number of display ads delivered during the month. Experian Interactive, which delivered a heavy rotation of ads for educational degree programs and credit scores, ranked second with nearly 1.3 billion impressions in the category. Two of the top ten advertisers on social networking sites in June delivered the vast majority of their impressions within the category. Pangea Media, which primarily advertises a variety of love and celebrity quizzes, delivered 90 percent of its ads on social networking sites, while online gaming provider Zynga delivered 97 percent of its ads on these sites.

“Social media is becoming an increasingly attractive vehicle for major advertisers seeking to optimize campaign reach and frequency and smaller advertisers desiring to reach a highly targeted audience,” added Hackett. “As social networking sites innovate on their existing ad offerings, the category should continue to grow in ad volume, while CPMs could also increase if the sites can demonstrate a high campaign ROI.”
