                 QVC ACHIEVES OPERATING CASH FLOW GROWTH OF 19%



Philadelphia, PA - August 1, 2001...Comcast Corporation today reported results
for the three and six months ended June 30, 2001.

Brian L. Roberts, president of Comcast Corporation said, "We are pleased to
report strong growth in all of Comcast's core businesses during the second
quarter. Comcast Cable's marketing and sales efforts, aggressive plant upgrades
and broadband service rollouts continue to yield industry-leading penetration
results and double-digit cash flow growth while maintaining strong margins.
Cable's impressive growth attests to the Company's ability to rapidly integrate
and upgrade acquired systems and deliver new products, while driving cash flow
margins on-par with or above the industry standard."

"As a result of strong market demand and our successful deployment strategies,
we are also pleased to increase guidance on our digital cable and high speed
data products. By year-end, we now anticipate having at least 2.2 million
Digital Cable subscriptions and 950,000 high-speed data subscribers."

Mr. Roberts added, "Our Commerce and Content results are equally exciting. QVC
again delivered outstanding results, with consolidated revenue growth of nearly
14% and consolidated operating cash flow growth of over 24% before start-up
costs for QVC-Japan, our most recent new market entry. Our content businesses
also generated double-digit revenue and cash flow growth, continuing to attract
larger audiences."


Cable Division Results

Pro forma cable division revenues for the quarter ended June 30, 2001 were
$1.285 billion, representing a 9.7% increase from the $1.171 billion in the
second quarter of 2000. Pro forma operating cash flow for the quarter was $561.7
million, an increase of 13.0% over the $497.1 million for the same period of
2000. Pro forma cable results for the second quarter assume that the Prime
acquisition, completed on August 1, 2000, the cable systems exchanges with AT&T
Corp. and Adelphia Communications Corp. completed on December 31, 2000 and on
January 1, 2001, respectively, and the acquisition of 585,000 cable subscribers
from AT&T completed on April 30, 2001 were effective on January 1, 2000. Pro
forma results exclude the acquisition of approximately 112,000 cable subscribers
from AT&T completed on June 30, 2001.

Cable subscribers grew to 8.307 million, a twelve-month trailing growth rate of
1%. Continuing strong demand for Comcast Digital Cable contributed to a 6.7%
increase in pro forma video revenues in the second quarter. High-speed data
service revenue more than doubled over the second quarter of 2000. Pro forma
advertising revenues grew 9.9% as the ongoing success of Comcast MarketLink, our
regional fiber interconnects, in attracting new advertising business helped
offset a generally weak advertising environment. Operating cash flow margins
improved to 43.7% from 42.5% reflecting the successful integration and improved
operating performance of recently acquired cable properties.


                                       2



Mr. Roberts said, "The cable division continues to deliver terrific operating
performance and growth, even as we integrate new cable systems and continue to
make significant investments in our cable infrastructure. During the second
quarter, we maintained our aggressive rebuild plan that will result in 95% of
all our systems being upgraded by the end of this year."

The cable division added 200,900 Digital Cable subscriptions in the second
quarter, a weekly average of approximately 15,500 to finish the quarter with
1.84 million Digital Cable units and a subscription penetration rate of nearly
23%. During the quarter, the cable division added more than 390,800
digital-ready subscribers to the Comcast Digital Cable footprint; this service
is now available to nearly 97% of Comcast's cable subscribers.

During the quarter, the cable division added 101,300 Comcast@Home customers, a
weekly average of approximately 7,800 net additions. At quarter end, 8.0 million
homes, or nearly 60% of the homes in Comcast's footprint were marketed the
Comcast@Home high-speed Internet service.


Commerce: QVC

QVC's consolidated revenues for the quarter ended June 30, 2001 were $876.0
million, representing a 13.7% increase from the $770.6 million reported in the
second quarter of 2000. Consolidated operating cash flow for the quarter was
$159.8 million, an increase of 19.3% over the $134.0 million reported in the
prior year quarter. Excluding the results of QVC-Japan, consolidated operating
cash flow increased 24.1% to $166.4 million.

Mr. Roberts said, "QVC's domestic business increased revenue by 15% and
continued to drive sustainable improvements in productivity that resulted in
operating cash flow growth of nearly 23% and cash flow margin expansion from
20.6% to 22.0%."


Content

Comcast's content businesses include E! Networks, Comcast-Spectacor, Home Team
Sports, acquired on February 14, 2001, and The Golf Channel, consolidated
effective June 2001, when Comcast increased its equity ownership to 91%. Pro
forma results assume that the Home Team Sports acquisition and the consolidation
of The Golf Channel occurred on January 1, 2000.

Solid growth in carriage continued to drive the results of E! Networks and The
Golf Channel, contributing to double-digit increases in revenue and operating
cash flow for both cable networks. As a whole, Comcast's content business
segment reported pro forma revenue and operating cash flow growth of 15.0% and
21.1%, respectively, in the second quarter.

                                       3



Business Communications

The Company's business communications results include the operating results of
new initiatives in both the U.S. and Europe.

Comcast Business Communications (CBC) reported revenues of $9.6 million and an
operating cash flow loss of $15.9 million in the second quarter as it continued
to build out its network in central and northern New Jersey and Philadelphia.
CBC has been established to further leverage Comcast's domestic cable
infrastructure by providing a complete voice, data and Internet service bundle
to small and medium-sized businesses in eight key markets served by Comcast
Cable.


Consolidated Financials

For the three months ended June 30, 2001, the Company reported consolidated
revenues of $2.299 billion, a 20.2% increase from the $1.912 billion reported in
the second quarter of 2000. Consolidated operating cash flow increased 16.2% to
$700.4 million from the $602.8 million reported in the second quarter of 2000.
The Company's consolidated results include the Prime acquisition, completed on
August 1, 2000, the cable systems exchanges with AT&T Corp. and Adelphia
Communications Corp. completed on December 31, 2000 and on January 1, 2001,
respectively, the acquisition of 585,000 cable subscribers from AT&T completed
on April 30, 2001, the acquisition of Home Team Sports on February 14, 2001, and
the consolidation of The Golf Channel as of June, 2001. Pro forma results assume
that all acquisitions and exchanges were effective on January 1, 2000. Pro forma
results exclude the acquisition of approximately 112,000 cable subscribers from
AT&T completed on June 30, 2001 although these assets are included in the
Company's balance sheet. On a pro forma basis, and excluding the effects of the
Company's new business communications initiatives, the Company's consolidated
revenues and operating cash flow for the quarter ended June 30, 2001 increased
11.4% and 16.0%, respectively, over the second quarter of 2000.

For the six months ended June 30, 2001, the Company reported consolidated
revenues of $4.495 billion, a 16.7% increase from the $3.851 billion reported in
the first half of 2000. Consolidated operating cash flow increased 12.7% to
$1.341 billion from the $1.190 billion reported for the six months ended June
30, 2000. On a pro forma basis, and excluding the effects of the Company's new
business communications initiatives, the Company's consolidated revenues and
operating cash flow for the six months ended June 30, 2001 increased 10.0% and
14.7%, respectively, over the same 2000 period.

(2)  Represents the gain recognized by the Company in connection with the settlement of its right under the June 2001 agreement
     described previously in note 2 to its Summary of Investments.

(3)  In connection with the adoption of SFAS No. 133, the Company reclassified its investment in Sprint PCS from an available for
     sale security to a trading security. The gain represents the accumulated unrealized gain on the Company's investment in Sprint
     PCS previously recorded as a component of accumulated other comprehensive income.

(4)  The Company records losses on its investments for which the Company has determined that a decline in value of the investment
     was considered other than temporary. The loss for the six months ended June 30, 2001 relates principally to the Company's
     investment in AT&T, a portion of which was exchanged on April 30, 2001.

(5)  Represents non-cash expense associated with the mark-to-market adjustment related to the Company's ZONES debt. Through December
     31, 2000, the ZONES were accounted for as an indexed debt instrument since the maturity value is dependent upon the fair value
     of Sprint PCS stock.

     Corporation in January 2001.

(7)  Represents the effects of adopting SFAS No. 133 in the first quarter of 2001.
