RESTON, VA, July 15, 2009 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced that it was ranked as the 15th largest U.S. market research firm based on 2008 domestic revenues, growing faster than each of the largest 25 research firms, according to the 2008 Honomichl report http://www.marketingpower.com/ResourceLibrary/MarketingNews/Pages/2009/43/7_30_09%20Pages/Honomichl_Top_50_Report.aspx. Published in Marketing News, a journal of the American Marketing Association, the Honomichl report ranked the top U.S. market research firms based on their 2008 revenues. Comscore ascended one position from the previous year with 2008 U.S. revenues growing 22 percent organically to $100.9 million. Comscore’s 2008 global revenue was $117.4 million.
