comScore Sponsors Planting of More Than One Million Trees In Developing Nations As Part Of Its Panel Recruitment Program

“Trees for Knowledge” Initiative Announced at Dedication of the Company’s New Global Headquarters in Reston, VA

Reston, VA July 29, 2008 – comScore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced a major initiative, “comScore Trees for Knowledge,” a partnership with the non-profit organization Trees for the Future. comScore’s initial donation will support the planting of one million trees in developing communities throughout the world as part of the incentive program that comScore uses to recruit and retain Internet users in its global panel. Under this initiative, comScore has also pledged to continue to make donations when new panel members join and remain active in the panel. The cost for this program is consistent with comScore’s historical and projected panel recruitment expense.

“It’s exciting to offer new comScore panelists the opportunity to participate in the comScore Trees for Knowledge program,” said Dr. Magid M. Abraham, President and CEO of comScore. “The comScore Internet user panel is the foundation of our business and the insights that our panelists provide is vital to the overall knowledge of global digital media usage. We believe the Tree for Knowledge program allows our panelists to make a dual contribution to increased Internet knowledge and a better environment.”

comScore’s research reports are derived from its global panel and are used by marketers, publishers, advertising agencies and financial analysts to better understand the rapidly evolving trends in Internet and mobile activity.

Since 1988, Trees for the Future has helped thousands of communities in Central America, Africa, and Asia improve their livelihoods and their environment by planting nearly 50 million trees. Trees for the Future calculates that each mature tree removes approximately 50 pounds of carbon dioxide from the atmosphere each year. The program is also active in the U.S., educating students and communities about global issues, the environment, and energy efficiency.

It is within the context of this significant expansion in all phases of our business that we required more space and facilities designed specifically for our needs.”
