                CNET, Inc. Completes Acquisition of mySimon, inc.

SAN FRANCISCO, Calif. March 1, 2000 -- CNET, Inc. today announced that it has
completed its acquisition of mySimon inc., effective February 29, 2000. CNET
issued a total of approximately 11 million shares of CNET common stock to
mySimon stockholders, valued at approximately $736 million based on the February
29 closing stock price. The mySimon acquisition is a pooling of interests
transaction.

CNET also announced that, effective yesterday, it has changed its corporate name
to CNET Networks, Inc. to reflect the mySimon acquisition and the company's
inclusion of new brands under the CNET banner.

The mySimon acquisition solidifies CNET's dominant position in the comparison
shopping space for computers and consumer electronics. The combination of CNET's
depth of content and mySimon's breadth of product categories and merchant search
capabilities is intended to simplify and to organize the e-commerce landscape by
creating a single destination devoted to informing online shoppers in every
category.

CNET and mySimon have already begun integrating CNET's industry leading content,
including product reviews, editors' top picks, news feeds and other resources
into the mySimon service.

Examples of the integration can be found here:

Integrated reviews and recommendations

In addition, CNET is planning to leverage mySimon's VLA Technology (Virtual
Learning Agent) within its own commerce services. The VLA Technology will enable
CNET to expand to more categories, adding product information and merchant
prices at a very rapid pace.

"First and foremost, the acquisition of mySimon clearly consolidated CNET's
position as the Internet's number one comparison shopping resource for computer
and consumer electronics products," stated Halsey Minor, CNET Chairman and CEO.
"I am pleased to note that the marriage has already begun to bear fruit, with a
sharing of best practices that has led to notable enhancements in both CNET's
commerce services and mySimon's computers and electronics categories."

Minor continued, "Going forward, this acquisition provides ready-made options to
extend our successful lead-based business model into new categories."

"CNET has already demonstrated its commitment to the success of mySimon and the
integrity of our combined vision of creating the definitive comprehensive
comparison shopping service for

just about anything on the Web," said Josh Goldman, President of mySimon, inc.
"Seeing what CNET and mySimon have been able to accomplish together in the past
few weeks confirms our hopes -- that this is a winning combination."
