ComScore's fourth quarter revenue in 2008 grew 25% versus fourth quarter 2007 to $31.6 million while subscription revenue grew by 32%.

The Reston, Va.-based company's full-year 2008 revenue grew 35% over 2007 to $117.4 million; full year adjusted net income grew by 36% and adjusted EBITDA grew by 43% over 2007.

"Overall revenue in the fourth quarter was slightly below the low end of our guidance range, impacted by somewhat lighter project revenue in the fourth quarter, the negative impact of the stronger U.S. dollar on our international revenue, and a slower rate of international growth," said Magid Abraham, comScore's president and chief executive officer. "We believe the lighter than expected project revenue can be attributed primarily to clients tightening their year-end spending in reaction to the economic slowdown."

The company added 112 gross new customers, or 30 new customers on a net basis, in the fourth quarter, which increased its total customer base to 1,166 clients. Comscore recently signed Viacom as the one-hundredth client for its Video Metrix video tracking service.--Tanya Irwin
