Comscore Releases Top Canadian Web Rankings for February 2008

Tax Category Experiences 17-Percent Jump in Visitors as Tax Deadline Looms

TORONTO, CANADA, March 27, 2008 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released its February 2008 rankings of the largest and fastest-growing Internet properties and site categories in Canada based on data from its Comscore MMX service. February, a month that generally exhibits lower visitation totals as a result of having fewer days, saw increases in the tax category as Canadians continued to prepare for tax season. The Mozilla Organization jumped 61 percent due to a Firefox browser upgrade, while Google Sites maintained its #1 position in the Top 25 Properties ranking for the second consecutive month, after first grabbing the top position in January.

“February’s seasonal decline in visitation means that few categories experienced gains during the month," said Brent Bernie, president of Comscore MMX, Comscore Canada. "However, with the April 30 deadline for tax filing fast approaching, the tax category was one of the biggest gainers for the month.”
