FOR IMMEDIATE RELEASE

COMCAST COMPLETES ACQUISITION OF JONES INTERCABLE, INC.


Philadelphia,  PA - March 2, 2000:  Comcast  Corporation  (NASDAQ:CMCSK,  CMCSA)
announced  today  that it has  completed  the  acquisition  by  merger  of Jones
Intercable,  Inc. (NASDAQ: JOIN, JOINA), previously a publicly-traded controlled
subsidiary of Comcast.  Each former Jones shareholder will receive 1.4 shares of
Comcast Class A Special Common Stock (CMCSK) for each share of Jones Intercable,
Inc. (JOIN and JOINA). In the merger,  Comcast issued approximately 58.9 million
shares of its Class A Special  Common  Stock and acquired the 60.4% of the stock
of Jones  Intercable,  Inc., that it did not previously own. As a result,  Jones
Intercable,  Inc. has been merged with and into Comcast JOIN  Holdings,  Inc., a
wholly-owned subsidiary of Comcast.

With the recent  acquisition of Lenfest  Communications,  Inc. and other pending
transactions,  Comcast  Cable will serve over 8.2 million  customers.  More than
four  million of these  customers  will be located in the  Mid-Atlantic  region,
stretching from New Jersey to suburban Washington, D.C. Comcast views geographic
consolidation  of key markets as critically  important to the company's  future,
enhancing its ability to offer expanded  digital video and  high-speed  Internet
access  services to its  customers and helping  accelerate  deployment of future
services, such as residential and commercial telephone, through its networks.

Comcast   Corporation   (www.comcast.com)   is   principally   involved  in  the
development,  management  and  operation  of  broadband  cable  networks and the
provision of programming content through its consolidated subsidiaries including
QVC, Comcast- Spectacor,  Comcast SportsNet and E! Entertainment  Television and
through other programming investments.

Comcast's  Class A Special  Common  Stock and Class A Common Stock are traded on
the Nasdaq Stock Market under the symbols CMCSK and CMCSA, respectively.
