TORONTO, CANADA, April 28, 2008 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released its March 2008 rankings of the largest and fastest-growing Internet properties and site categories in Canada based on data from its Comscore MMX service. Canadians focused their attention on their finances in March with online trading, taxes and personal finance sites all experiencing gains, as visitors prepared to meet the tax deadline and braced for a possible economic slowdown.

“Canadians showed strong engagement with tax, banking and government sites in March,” said Brent Bernie, president of Comscore MMX, Comscore Canada. “With the tax deadline quickly approaching, it is no surprise that this month saw Canadians turn to the Web to file their taxes and manage their finances during these challenging economic times.”
