RESTON, VA – comScore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, released its monthly analysis of U.S. consumer activity at the top online properties for April 2009 based on data from the comScore Media Metrix service. April saw Americans turn to the Web for the latest information related to the swine flu, causing traffic to soar at CDC.gov. The month also saw visitation to social networking sites reach record numbers, driven by growth at Twitter.com and Facebook.com, as well as an increase in visitation to real estate and home-related sites as the spring season prompted many Americans to consider home improvements. The tax category also experienced strong growth as procrastinating Americans tried to beat the April 15 deadline.

“When news of the swine flu pandemic erupted, many Americans turned to the Internet as their primary source of information for how to keep themselves and their families safe,” commented Jack Flanagan, executive vice president of comScore Media Metrix. “April also saw a record number of visitors at social networking sites with Facebook and Twitter each adding millions of new users as a result of continued media attention and overall interest in the sites.”
