U.S. Retail E-Commerce Sales in October 2007 Grow 19 Percent versus Last Year

Video Games, Consoles & Accessories Continue to Post Strong Growth

RESTON, VA, November 13, 2007 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released U.S. e-commerce spending figures for October 2007, showing that retail e-commerce increased 19 percent versus year ago to nearly $10 billion.

The October growth rate marked a slight decline from the growth rates observed earlier in the year. In particular, retail e-commerce sales year-to-date through September grew at approximately 21 percent, meaning that the 19-percent growth in October represented a slightly softer-than-average month.

“October e-commerce activity often gives us a glimpse of what to expect during the holiday season,” said Comscore Chairman Gian Fulgoni. “That online sales growth rates diminished slightly in October is not entirely unexpected, as many consumers are feeling the pinch of ballooning mortgages and gas prices, coupled with a decline in housing values. Even the rapidly growing online commerce sector appears to not be immune from these economic realities.”

What’s Hot in the Pre-Holiday Shopping Season?

The video games, consoles & accessories category posted the strongest gains in October versus last year, jumping 264 percent, as sales of Nintendo Wii and Sony PlayStation consoles and accessories, as well as popular video game Halo 3, continued to drive growth in the category. Furniture, appliances & equipment also experienced a strong month, growing 105 percent versus last year, followed by computer software (up 76 percent) and event tickets (up 43 percent). Meanwhile, apparel & accessories, one of the largest online retail categories, grew just 5 percent in October.

“Soft online apparel sales in October mirror reports of declining same-store sales figures in retail apparel, as unseasonably warm weather across many part of the country appeared to dampen consumer demand,” continued Mr. Fulgoni. “Excluding apparel from our analysis, online retail sales actually grew at a healthier 22-percent rate. Assuming that apparel sales rebound during November and December, this suggests that 2007 may well see another merry Christmas for online retailers.”

Comscore will be publishing its first look at holiday season e-commerce spending figures next week and will continue with twice weekly updates throughout the season.
