(NASDAQ: SCOR), a leader in measuring the digital world, today released its monthly analysis of U.S. consumer activity at the top online properties for March 2008 based on data from the comScore Media Metrix service. March saw traffic increase to online radio, gambling and retail-health care sites.

“American sports factored in prominently for the top gaining categories and properties in March,” said Jack Flanagan, executive vice president of comScore Media Metrix. “The NCAA tournament drove substantial traffic to online gambling sites during the month, while the start of spring training made MLB.com one of the top gaining properties.
