                     COMCAST CORPORATION TO PARTICIPATE IN
                    BEAR STEARNS ANNUAL MEDIA, ENTERTAINMENT
                           AND INFORMATION CONFERENCE

Philadelphia, PA - March 4, 2002 - Comcast Corporation today will participate
in the Bear Stearns Annual Media, Entertainment and Information Conference to
be held in Palm Beach, Florida.

During the conference, members of the Company's senior management will review
the performance of Comcast's cable, commerce and content business segments
during the year 2001 and reaffirm its growth prospects and financial
expectations previously disclosed in the fourth quarter 2001 earnings release
and conference call, which are posted on the Company's website. The Company
will provide an update on its proposed financing plans related to the recently
announced combination of AT&T Broadband with Comcast. In connection with this
update, management will discuss the proposed legal and organizational structure
for the combined company's balance sheet.

In Cable, Comcast will provide examples of its successful integration of cable
systems acquired over the past twelve months. As a result of the 95% completion
of the cable rebuild in 2001, Comcast expects a significant reduction in cable
capital spending in 2002 to drive free cash flow in 2002.






Leveraging its upgraded network, the Company will also review the growth
prospects of its new services, including Comcast Digital Cable and Comcast
High-Speed Internet service. Comcast believes these new digital and broadband
services represent the platform for future new services and growth such as
video-on-demand and high-definition television.

Live audio and presentation slides will be available today at 3:45 pm (EST) on
the Company's website at www.cmcsk.com   [http://www.cmcsk.com]. An on demand
replay of the presentation will be available within 24 hours.
