     PHILADELPHIA, Feb. 3 -- Comcast Corporation (Nasdaq: CMCSA, CMCSK) today
reported results for the quarter and year ended December 31, 2004. Comcast will
discuss its 2004 results and 2005 outlook on a conference call and webcast today
at 8:30 AM Eastern Time. A live broadcast of the conference call will be
available on the investor relations website at http://www.cmcsa.com and
http://www.cmcsk.com.

     Brian L. Roberts, Chairman and CEO of Comcast Corporation said, "We are
delighted to report terrific results for 2004 that include surpassing $20
billion in revenue for the first time in our history. Cable division revenue
increased more than 10% to $19.3 billion, and cable Operating Cash Flow
increased nearly 18% to $7.5 billion. We generated nearly $2 billion of Free
Cash Flow, made strategic investments to drive product differentiation and
growth, and returned $1.3 billion to shareholders through our stock buyback
program. As we begin 2005, we are well positioned for sustained growth."

     "Our 2004 results demonstrate clear consumer demand for all of our new
product offerings, led by Comcast High-Speed Internet that added a record 1.7
million new customers in 2004. We expect robust customer additions to continue
in 2005 as we maintain our focus on adding new applications and value to this
service."

     "More than 8.6 million, or 40%, of our subscribers now subscribe to Comcast
Digital Cable, enjoying new digital features like ON DEMAND, HDTV programming
and DVR functionality. Our ON DEMAND service is taking off - our customers
ordered more than 560 million ON DEMAND programs during 2004 and we expect to
exceed one billion orders in 2005. With features like ON DEMAND now widely
available to our customers, 2005 promises to be another great year for our video
services."

     "It is an exciting time at Comcast as we drive product innovation and
differentiation in every area of our business. In 2004, we made several
strategic investments in new technologies and content to strengthen our
competitive advantage. I am thrilled with the way our talented team is enhancing
our services, including our extensive and rapidly-growing ON DEMAND offering,
our expanding portfolio of regional sports programming and our industry-leading
Comcast.net portal. These features distinguish our video and high-speed Internet
products and will contribute to our growth."

<PAGE>

     "In 2005, we will extend our product offerings even further with the
introduction of Comcast Digital Voice. As we begin to integrate this new service
with Comcast's video and High-Speed Internet services, our goal is to build a
unique experience for our customers, to differentiate our products and our
company from the competition, and to deliver growth and increasing value to our
shareholders."

     Fiscal Year 2004
     Comcast Cable delivered solid results for 2004:

                                      Guidance                  Results

     Capital expenditures       $3.3 - $3.4 billion         $3.622 billion

     For the year ended December 31, 2004, Comcast Cable reported revenue of
$19.321 billion, a 10.4% increase from the same period in 2003. Video revenue
increased 6.5% during the period, reflecting the addition of 990,000 new digital
cable subscribers and price increases to our video service. Growth in video
revenue and digital subscribers also reflects increasing consumer demand for new
digital features, including Comcast ON DEMAND, high-definition television (HDTV)
programming and digital video recorders (DVRs). With more than 8.6 million
subscribers, digital cable penetration reached 40.2% at December 31, 2004, an
increase from the 35.6% penetration reported one year ago. During 2004,
pay-per-view revenues increased nearly 21% to $393 million, driven by more movie
and event purchases through the Comcast ON DEMAND service. Comcast Cable added
8,000 basic subscribers during 2004, ending the year at 21.548 million.

<PAGE>

     Comcast High-Speed Internet service revenue increased 38.6% during the year
ended December 31, 2004, to $3.124 billion, reflecting the record addition of
1.707 million new subscribers and stable average monthly revenue per subscriber
for the year of $42.41 compared to $42.20 for 2003. Comcast High-Speed Internet
service is now available to 40 million homes, almost all of Comcast's footprint,
as compared to 35 million homes at the start of 2004.

     Advertising revenue increased 15.7% from the year-ago period to $1.287
billion, reflecting growth of 7.0% in local advertising and growth of 23.3% in
regional/national advertising as a result of the ongoing success of our regional
interconnect strategy and a significant increase in political advertising during
the third and fourth quarters of 2004.

     As expected, cable phone revenue declined 12.5% during 2004 to $701
million, the result of a 3.4% decrease in subscribers and a 4.9% decrease in
average monthly revenue per subscriber to $46.90. Cable phone results reflect
the Company's ongoing focus on profitability, rather than unit growth, of its
circuit-switched telephone business as it begins the transition to Comcast
Digital Voice service using IP technology in 2005. Comcast expects to market
Comcast Digital Voice service to 15 million homes by the end of 2005 with most
markets launching in the second half of the year. Excluding phone revenue, which
is expected to continue to decline in 2005, total revenue for Comcast Cable
increased 11.5% during 2004 to $18.620 billion.

     Comcast Cable operating income before depreciation and amortization
(Operating Cash Flow) grew 17.6% during 2004 to $7.473 billion, reflecting
strong revenue growth and the Company's continuing success in controlling the
growth of expenses in nearly every area of the business.

     Cable capital expenditures for the year ended December 31, 2004, declined
11.6% to $3.622 billion compared to $4.097 billion in the prior year. The
decline in 2004 cable capital expenditures reflects a $512 million, or 36%
decrease in upgrade investment due to the substantial completion of the
Company's cable system upgrade. Upgrade capital expenditures of $902 million in
2004 will decline further in 2005, by approximately 75% due to the substantial
completion of our cable system upgrade. Capital expenditures were approximately
$200 million greater than guidance due primarily to the purchase of advanced
set-top boxes at the end of December 2004.

     Fourth Quarter 2004
     For the quarter ended December 31, 2004, Comcast Cable reported revenue of
$4.987 billion, representing a 10.6% increase from the prior year quarter. Video
revenue increased 5.9% during the period, reflecting the addition of digital
cable subscribers and price increases to our video service. Comcast Cable added
more than 250,000 digital cable subscribers during the fourth quarter to end the
period with greater than 8.6 million subscribers. Comcast Cable added 60,000
basic subscribers during the seasonally strong fourth quarter of 2004, ending
the year at 21.548 million.

     During the fourth quarter of 2004, Comcast Cable added more than 437,000
high-speed internet subscribers to end the quarter with nearly 7.0 million
subscribers. Revenues for this service increased 35.9% from the prior year
quarter to $855 million, reflecting solid subscriber growth and slightly

<PAGE>

higher average monthly revenue per subscriber for the quarter of $42.07, an
increase from $41.33 during the same quarter of 2003. Advertising revenue
increased 17.2% from the fourth quarter of 2003 to $369 million, including
increased political advertising during the quarter. Cable phone revenue declined
5.2% from the same period one year ago to $173 million, primarily due to fewer
subscribers in the fourth quarter of 2004 compared to 2003. Comcast Cable added
more than 10,000 phone subscribers in the fourth quarter of 2004.

     Operating Cash Flow grew 15.2% from the same quarter one year ago to $1.974
billion, reflecting strong revenue growth and the Company's success in
controlling the growth of operating costs. Comcast Cable capital expenditures
were $1.044 billion in the fourth quarter of 2004 compared to $1.052 billion in
the fourth quarter of 2003.

     Content
     Comcast's content segment consists of the national networks E!
Entertainment Television and Style Network (E! Networks), The Golf Channel,
Outdoor Life Network, G4techTV and International Channel Networks.

     Comcast's content businesses reported strong results in 2004:

                                                  Results Comparable    Segment
                                   Guidance (1)     to Guidance (1)     Results
                                   -----------    ------------------    -------
     Revenue growth                At least 20%          20.8%           25.3%
     Operating Cash Flow growth    At least 30%          29.0%           24.0%

     (1) Guidance excluded the results of TechTV and International Channel
         Networks that were acquired during the year.

     The content businesses essentially met guidance for the year that excluded
the results of TechTV and International Channel Networks. The content businesses
posted solid results reflecting double digit revenue growth at all of the
networks and strong growth in Operating Cash Flow.

     Comcast's content segment reported 2004 revenue for the year ended December
31, 2004, of $787 million, a 25.3% increase from 2003 reflecting increases in
distribution and advertising revenue for all of the networks and the inclusion
of TechTV and International Channel Networks in the 2004 results. The Content
segment reported Operating Cash Flow of $265 million in 2004, a 24.0% year over
year increase to 2003, reflecting strong growth at The Golf Channel and Outdoor
Life Network offset by higher operating expenses at E! Networks and the
inclusion of TechTV and International Channel Networks in the 2004 results.

     For the quarter ended December 31, 2004, Comcast's Content segment reported
revenue of $205 million, a 23.4% increase compared to the prior year period, and
Operating Cash Flow of $57 million, a decline of 2.8% from the fourth quarter of
2003. The decline in fourth quarter 2004 Operating Cash Flow was due to strong
growth at the Outdoor Life Network offset by higher operating expenses at E!
Networks and G4techTV.

     Corporate and Other
     Corporate and Other includes Comcast-Spectacor, corporate overhead and
other operations and eliminations between Comcast's businesses. For the year
ended December 31, 2004, Comcast reported Corporate and Other revenue of $204
million and an Operating Cash Flow loss of $205 million compared to revenue of
$228 million and an Operating Cash Flow loss of $172 million in 2003.

     For the three months ended December 31, 2004, Corporate and Other revenue
declined to $43 million from the $69 million reported in the same period of
2003. The Operating Cash Flow loss for the quarter ended December 31, 2004, was
$45 million compared to $51 million in 2003. Results for the year and quarter
ended December 31, 2004, were impacted by the absence of National Hockey League
games.

     Consolidated Results
     Comcast sold its 57% ownership interest in QVC in September 2003. QVC's
results, prior to its sale, are presented as discontinued operations.
Consolidated amounts primarily reflect the results of the cable division, as
discussed above.

     For the year ended December 31, 2004, the Company reported consolidated
revenues of $20.307 billion, a 10.7% increase from the $18.348 billion reported
in 2003. Consolidated Operating Cash Flow increased to $7.531 billion, or 17.8%,
in 2004 from the $6.392 billion reported in the prior year. Operating income
increased 48.8% to $2.908 billion in 2004 compared to operating income of $1.954
billion in 2003. Investment income increased from a loss of $84 million in 2003
to income of $472 million in 2004. The increase in investment income was due to
mark-to-market adjustments to our investment portfolio. Other income increased
from $71 million in 2003 to $394 million in 2004, reflecting the positive impact
of the settlement of previously disclosed litigation for an amount significantly
less than previously estimated.

     For the year ended December 31, 2004, the Company reported consolidated net
income of $970 million, or $0.43 per share compared to a consolidated loss from
continuing operations of $218 million, or a loss of $0.10 per share in 2003.
Please refer to the "Reconciliation of Net Income to Free Cash Flow" in Table
7-B at the end of this release and the Company's Form 10-K for further details
on items affecting net income.

     Comcast reported significant Free Cash Flow in 2004:

                                        Guidance         Results
                                       ----------     -------------
     Consolidated Free Cash Flow       $2 billion     $1.937 billion

     Free Cash Flow (which is defined in Table 4) was $1.937 billion in 2004, a
significant increase from the $74 million of Free Cash Flow reported in 2003.
The increase was driven by growth in Operating Cash Flow and lower capital
expenditures as a result of the substantial completion of the Company's cable
system upgrade. Free Cash Flow results for 2004 were slightly less than guidance
of $2 billion due to increased capital expenditures in December 2004, as
described above.

<PAGE>

     For the three months ended December 31, 2004, the Company reported
consolidated revenues of $5.235 billion, a 10.4% increase from the $4.742
billion reported in the same period of 2003. Consolidated Operating Cash Flow
increased to $1.986 billion, or 15.5%, in the fourth quarter of 2004 from the
$1.720 billion reported in the same prior year period. Operating income
decreased 4.1% to $711 million in the fourth quarter of 2004 compared to
operating income of $742 million in 2003. The decline in operating income was
due to higher depreciation expense related to capital expenditures in 2004 and
the effect of acquisition adjustments that lowered amortization expense in the
fourth quarter of 2003. Other income increased from $11 million in 2003 to $312
million in 2004, reflecting the positive impact of the settlement of previously
disclosed litigation for an amount significantly less than previously estimated.

     For the three months ended December 31, 2004, the Company reported
consolidated net income of $423 million, or $0.19 per share compared to
consolidated income from continuing operations of $383 million, or $0.17 per
share for the three months ended December 31, 2003. Please refer to the
"Reconciliation of Net Income to Free Cash Flow" in Table 7-B at the end of this
release and the Company's Form 10-K for further details on items affecting net
income.

     Share Repurchase Program
     Comcast repurchased $1.3 billion, or 46.9 million shares, of its common
stock under its stock repurchase program during 2004. Comcast expects such
repurchases to continue to occur from time to time in the open market or in
private transactions, subject to market conditions. During the fourth quarter of
2004, Comcast repurchased $303 million, or 10.1 million shares of its common
stock.

     In addition, the Company elected to redeem, in cash, several debt issues
during 2004 for a total of $609 million that were exchangeable into Comcast
Class A Special Common Stock, eliminating the need to issue 22.5 million
additional shares.

     Since the inception of the program in December 2003 through December 31,
2004, the Company has repurchased $1.4 billion of its Class A Special Common
Stock, or 47.8 million shares, under its $2 billion share repurchase program.
Including the $609 million paid in cash to redeem several debt issues
exchangeable into Comcast common stock, the Company has invested $2.0 billion in
its common stock and related securities.

     2005 Financial Outlook:

     For 2005, Comcast expects:

     --   Consolidated revenue growth of approximately 10%
     --   Consolidated Operating Cash Flow growth of at least 12%*
     --   Consolidated capital expenditures of approximately $3 billion
     --   Consolidated Free Cash Flow growth of between 35% and 45%*
     --   Total Revenue Generating Unit growth of at least 2.5 million units

(1)  Free Cash Flow is defined as Operating Cash Flow less net interest, cash
     paid for taxes, and capital expenditures. It is unaffected by fluctuations
     in working capital levels from period to period and cash payments
     associated with intangible and other noncurrent assets. Cash payments for
     intangible and other noncurrent assets include long-term technology license
     agreements including computer software, long term rights to service
     multi-dwelling properties and programming content for our cable networks.
     In 2004, cash payments for intangible assets also included a long-term
     strategic license agreement with Gemstar of approximately $250 million.

(2)  Includes interest expense net of interest income and excludes non-cash
     interest and subsidiary preferred dividends.

<PAGE>

(3)  Excludes income tax refunds of $591 million received in 2004 and a payment
     of $850 million associated with the sale of QVC in 4Q03.

(4)  Free Cash Flow excludes amounts necessary to reconcile Free Cash Flow to
     "Net Cash Provided by Operating Activities Less Capital Expenditures." In
     2004, these amounts include proceeds of $680 million related to the
     exchange/sale of Liberty Media and Liberty Media International stock and
     proceeds of $591 million related to income tax refunds, offset by $515
     million in cash payments for liabilities recorded as part of the
     acquisition of AT&T Broadband and the timing of payments made during the
     first quarter of 2004. For 2003, these amounts include $836 million in cash
     payments associated with the acquisition of AT&T Broadband and a cash
     payment of $850 million for income taxes associated with the sale of QVC.

     CPE includes costs incurred at the customer residence to secure new
     customers, revenue units and additional bandwidth revenues (e.g. digital
     converters). Scalable infrastructure includes costs, not CPE or network
     related, to secure growth of new customers, revenue units and additional
     bandwidth revenues or provide service enhancements (e.g. headend
     equipment). Line extensions include network costs associated with entering
     new service areas (e.g. fiber/coaxial cable). Upgrades include costs to
     enhance or replace existing fiber/coaxial cable networks, including
     recurring betterments. Support capital includes costs associated with the
     replacement or enhancement of non-network assets due to obsolescence and
     wear out (e.g. non-network equipment, land, buildings and vehicles).

     Non-GAAP and Other Financial Measures
     Operating Cash Flow is the primary basis used to measure the operational
strength and performance of our businesses. Free Cash Flow is an additional
performance measure used as an indicator of our ability to repay debt, make
investments and return capital to investors, principally through stock
repurchases. We use Debt Excluding Exchangeables as a measure of debt that will
require cash from future operations or financings. We also adjust certain
historical data on a pro forma basis following significant acquisitions or
dispositions to enhance comparability.

<PAGE>

     Operating Cash Flow is defined as operating income before depreciation and
amortization and impairment charges, if any, related to fixed and intangible
assets and gains or losses from the sale of assets, if any. As such, it
eliminates the significant level of non-cash depreciation and amortization
expense that results from the capital intensive nature of our businesses and
intangible assets recognized in business combinations, and is unaffected by our
capital structure or investment activities. Our management and Board of
Directors use this measure in evaluating our consolidated operating performance
and the operating performance of all of our operating segments. This metric is
used to allocate resources and capital to our operating segments and is a
significant component of our annual incentive compensation programs. We believe
that Operating Cash Flow is also useful to investors as it is one of the bases
for comparing our operating performance with other companies in our industries,
although our measure of Operating Cash Flow may not be directly comparable to
similar measures used by other companies.

     As Operating Cash Flow is the measure of our segment profit or loss, we
reconcile it to operating income, the most directly comparable financial measure
calculated and presented in accordance with Generally Accepted Accounting
Principles (GAAP), in the business segment footnote of our quarterly and annual
financial statements. Therefore, we believe our measure of Operating Cash Flow
for our business segments is not a "non-GAAP financial measure" as contemplated
by Regulation G adopted by the Securities and Exchange Commission. Consolidated
Operating Cash Flow is a non-GAAP financial measure.

     Free Cash Flow, which is a non-GAAP financial measure, is defined as
Operating Cash Flow less net interest, cash paid for taxes, and capital
expenditures. As such, it is unaffected by fluctuations in working capital
levels from period to period and cash payments associated with intangible assets
which are detailed in our quarterly and annual reports on Forms 10Q/K. We
believe that Free Cash Flow is also useful to investors as it is one of the
bases for comparing our operating performance with other companies in our
industries, although our measure of Free Cash Flow is accrual-based and may not
be comparable to similar measures used by other companies.

     Debt Excluding Exchangeables, which is a non-GAAP financial measure, refers
to the aggregate amount of our consolidated debt and capital lease obligations
less the amount of notes that are collateralized by securities that we own.

     Pro forma data is used by management to evaluate performance when
significant acquisitions or dispositions occur. Historical data reflects results
of acquired businesses only after the acquisition dates while pro forma data
enhances comparability of financial information between periods by adjusting the
data as if the acquisitions (or dispositions) occurred at the beginning of the
prior year. Our pro forma data is only adjusted for the timing of acquisitions
and does not include adjustments for costs related to integration activities,
cost savings or synergies that have been or may be achieved by the combined
businesses. We believe our pro forma data is not a non-GAAP financial measure as
contemplated by Regulation G.

     Operating Cash Flow and Free Cash Flow should not be considered as
substitutes for operating income (loss), net income (loss), net cash provided by
operating activities or other measures of performance or liquidity reported in
accordance with GAAP. Debt Excluding Exchangeables should not be considered as a
substitute for Total Debt. Additionally, in the opinion of management, our pro
forma data is not necessarily indicative of future results or what results would
have been had the acquired businesses been operated by us after the assumed
earlier date.

     Following are quantitative reconciliations of Free Cash Flow, Debt
Excluding Exchangeables, Consolidated Operating Cash Flow, and, although not
required by Regulation G, reconciliations of business segment Operating Cash
Flow and pro forma data.
