Comscore Accurately Predicts Q4 2006 Retail E-Commerce Sales Within 3 Percent of U.S. Department Of Commerce Estimates

Comscore Sales Data Available Six Weeks Before Commerce Department Report

RESTON, VA, March 5, 2007 – Comscore Networks, a leader in measuring the digital age, today reported that its U.S. e-commerce sales estimates for the fourth quarter of 2006 were once again closely aligned with the U.S. Department of Commerce estimates. Comscore data show that online non-travel (“retail”) spending, excluding event tickets but including auction commissions, increased to $33.1 billion during Q4 2006 versus the Department of Commerce’s estimate of $33.9 billion. Comscore’s fourth quarter e-commerce sales data were published during the first week of January 2007, a full six weeks before the Department of Commerce’s February 16, 2007 release of its own estimates.

“Comscore’s track record of accuracy in measuring e-commerce sales is a testament to the representivity of the Comscore panel and the quality of Comscore’s rigorous data collection processes,” said Gian Fulgoni, chairman of Comscore Networks. “With consumers’ online spending now exceeding $100 billion annually and still growing at a rate in excess of 25 percent per year, it’s clear that e-commerce has come of age. And we are delighted to be one of the standards by which the online industry measures its performance.”
