New Comscore Tech Metrix Service Tracks Computer Hardware Configurations and Software Usage

Hard Drive Capacity on Americans’ Home PCs Expands in 2007

MP3 Files Consume Average of 3 GB per Home PC

RESTON, VA, August 1, 2007 – Comscore (NASDAQ: SCOR), a leader in measuring the digital world, today announced the launch of Comscore Tech Metrix, a new service to provide a detailed view of Internet users’ individual technology profiles, including computer hardware, software configurations, and usage.

The computer hardware/system information measured by Comscore Tech Metrix includes: system manufacturer, processor name/type, operating system, service pack, CPU, RAM, hard drive size, CD rom or DVD drive, screen resolution, video and sound cards, and more. The software tracking includes: installed programs and version number, interactive duration, default browser and browser settings, number and size of data files, and multimedia file types.

Comscore Tech Metrix will help hardware/software product development and marketing teams improve product planning and market more intelligently in the following ways:

• Tailor product developments to customers’ most common computer configuration settings
• Understand trends in adoption rates among various market segments
• Track customer loyalty and emerging competitive threats
• Determine product market share versus competitors
• Design marketing programs based on deeper knowledge of one’s customer base
• Identify cross-promotion opportunities
• Facilitate more targeted, measurable and cost-effective online campaigns

“Comscore Tech Metrix represents Comscore’s first foray into non-Web based measurement,” said Linda Boland Abraham, executive vice president at Comscore. “This service will enable product developers and marketers to better tailor offerings to their core constituencies by understanding the technical underpinnings of their customers’ computer usage. When combined with Web behavior profiles, Tech Metrix data will help marketers develop a granular perspective of the machine configuration and behavior of key customer segments, along with how and where to reach them on the Web.”

Hard Drive Space Shows Gains since Beginning of 2007

The debut Comscore Tech Metrix report revealed that the average hard drive capacity on U.S. computers is demonstrating steady and noticeable gains since the beginning of the year. The percentage of computers with at least 70 GB of hard drive space has increased from 33 percent of computers in January 2007 to 39 percent in April 2007. Meanwhile, the percentage of computers with less than 50 GB declined from 59 percent to 53 percent during the same period.

MP3s Consume Average of 3 GB per U.S. Computer

Comscore Tech Metrix also reports on the different file types residing on the computer. In April, the typical computer in the U.S. contained 880 mp3 files, which accounted for an average of 3 GB of hard drive space. The average computer also contained 197 Microsoft Word (.doc) documents, 100 PDF (.pdf) files, 77 Microsoft Excel (.xls) files, and 36 Windows Media (.wmv) files. The average Windows Media file size is 12.5 MB.

Behavioral Profiling Capabilities

Another attractive aspect of Comscore Tech Metrix is the ability to create user segments based on their technology profiles and to then analyze the online behavior of those segments. As an example, Comscore profiled the online behavior of Heavy mp3 users compared to the average Internet user:

* Heavy mp3 users = top 50 percent of PC users with most mp3 files on computer
** Index = Reach of Heavy mp3 users/ reach of average Internet users x 100; Index of 100 represents parity

As one might expect, the Heavy mp3 segment was significantly more likely to visit categories dealing in entertainment (gaming, gambling, humor, music) and communication/networking (community – teens, instant messengers, discussion/chat). Specifically, nearly 40 percent of Heavy mp3 users visited the gaming information category, more than twice as likely as the average Internet user. They also exhibited particularly heavy relative visitation to the online gambling, community – teens, and entertainment – humor categories.

While Heavy mp3 users are engaged with leisure pursuits online, Heavy Microsoft Word users have a markedly different behavioral profile:

* Heavy MS Word users = top 50 percent of PC users with most MS Word documents on computer
** Index = Reach of Heavy MS Word users/ reach of average Internet users x 100; Index of 100 represents parity

Their profile is highly indicative of business-oriented individuals, as evidenced by their likelihood of visiting categories dealing with business and finance (taxes, finance news/research, online trading, B-to-B) and travel (airlines, hotels/resorts).
