UBID REPORTS RECORD GROWTH

Continued Increases in Major Site Metrics and New Programming Interface

Strongly Position Company for Upcoming Holiday Season

CHICAGO, IL – October 9, 2001 – uBid.com, a leading retail auction and e-commerce marketplace and majority-owned operating company of CMGI, Inc. (NASDAQ: CMGI), today announced continued strong growth despite volatility in the larger retail economy. The company indicated that site traffic was up more than 27 percent month-to-date. In addition, uBid showed an increase of more than 34 percent in credit card registrations from the previous month.

uBid continues to expand its inventory with more than 18 million items available for auction, an increase of 48 percent from the previous month. The company also reported that the number of new consumer-to-consumer auctions listed each day has grown to 6,500, up 36 percent from the same period last month.

”Despite the larger economic slowdown, we have recently seen significant increases in our most important site and user metrics, including our strongest ever monthly start for traffic and credit card registrations,” said Tim Takesue, acting Chief Executive Officer for uBid. “Our ability to provide an unprecedented combination of options for cost-conscious consumers looking for bargains, as well as manufacturers looking to turn inventory, is a strong positive indicator as we enter the important holiday selling season.”

In addition, uBid recently launched its new Application Programming Interface, or API, allowing outside partners a more convenient and reliable way to access uBid’s auction system for listing products. Instead of relying upon HTML, the new API establishes a connection using the increasingly popular XML programming language, providing a more robust and hassle-free interface for entering new listings into the uBid site.

“The new API enables users to more efficiently and effectively post listings into uBid, thus further increasing the total number of items available for auction,” added Takesue. “The API was implemented to help increase site transactions and overall sales, as well as to help our customers, and in turn our business, expand into new markets.”

According to the May eCommercePulse issued by Nielsen//NetRatings and Harris Interactive 2001, uBid ranks No. 2 in total revenue share in the online auction market. The eCommercePulse findings were concurrent with uBid’s recognition as the Top E-Business Winner in the Internet Companies category in this year's InternetWeek 100, an annual InternetWeek magazine study that highlights the 100 largest and most successful businesses across 10 major industries who are leveraging Internet technologies to drive e-business results.
