     This Quarterly  Report on Form 10-Q is for the three months ended March 31,
1999.  This Quarterly  Report  modifies and supersedes  documents filed prior to
this  Quarterly  Report.  The  SEC  allows  us  to  "incorporate  by  reference"
information that we file with them,  which means that we can disclose  important
information  to you by referring  you directly to those  documents.  Information
incorporated by reference is considered to be part of this Quarterly  Report. In
addition,  information  we file with the SEC in the  future  will  automatically
update and supersede  information  contained in this Quarterly  Report.  In this
Quarterly Report,  "Comcast," "we," "us" and "our" refer to Comcast  Corporation
and its subsidiaries.

     You should  carefully  review the  information  contained in this Quarterly
Report and in other reports or documents that we file from time to time with the
SEC. In this Quarterly  Report, we state our beliefs of future events and of our
future  financial  performance.  In some cases, you can identify those so-called
"forward-looking   statements"  by  words  such  as  "may,"  "will,"   "should,"
"expects,"  "plans,"   "anticipates,"   "believes,"   "estimates,"   "predicts,"
"potential,"  or "continue" or the negative of those words and other  comparable
words.  You  should be aware  that those  statements  are only our  predictions.
Actual events or results may differ materially.  In evaluating those statements,
you should specifically  consider various factors,  including the risks outlined
below.  Those factors may cause our actual results to differ materially from any
of our forward-looking statements.

Factors Affecting Future Operations

     The cable communications  industry and the provision of programming content
may be affected by, among other things:

     o    changes in laws and regulations,
     o    changes in the competitive environment,
     o    changes in technology,
     o    franchise  related  matters,  
     o    market  conditions that may adversely  affect the availability of debt
          and equity  financing for working  capital,  capital  expenditures  or
          other purposes,
     o    demand for the programming content we distribute or the willingness of
          other video program providers to carry our content,
     o    general economic conditions.

1.   CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

     Basis of Presentation
     The condensed  consolidated  balance sheet as of December 31, 1998 has been
     condensed from the audited  consolidated balance sheet as of that date. The
     condensed consolidated balance sheet as of March 31, 1999 and the condensed
     consolidated  statements of operations and accumulated  deficit and of cash
     flows for the three months ended March 31, 1999 and 1998 have been prepared
     by Comcast  Corporation  (the  "Company")  and have not been audited by the
     Company's  independent   auditors.  In  the  opinion  of  management,   all
     adjustments (which include only normal recurring  adjustments) necessary to
     present fairly the financial position, results of operations and cash flows
     as of March 31, 1999 and for all periods presented have been made.

     Certain information and note disclosures normally included in the Company's
     annual financial  statements prepared in accordance with generally accepted
     accounting  principles  have been  condensed  or omitted.  These  condensed
     consolidated  financial  statements  should be read in conjunction with the
     financial  statements and notes thereto included in the Company's  December
     31, 1998 Annual Report on Form 10-K filed with the  Securities and Exchange
     Commission.  The results of operations  for the period ended March 31, 1999
     are not necessarily indicative of operating results for the full year.

     The  results  of  operations  of  Comcast  Cellular  Corporation  ("Comcast
     Cellular"),  an indirect wholly owned subsidiary of the Company,  have been
     presented  as  a  discontinued  operation  in  accordance  with  Accounting
     Principles Board ("APB") Opinion 30, "Reporting the Results of Operations -
     Reporting  the  Effects  of  Disposal  of  a  Segment  of a  Business,  and
     Extraordinary,  Unusual and Infrequently Occurring Events and Transactions"
     (see Note 3).

     Stock Split
     On March 3, 1999, the Company's  board of directors  authorized an increase
     in the number of authorized  shares of the Company's Class A Special Common
     Stock from 500 million  shares to 2.5  billion  shares.  On that date,  the
     Company's board of directors also  authorized a two-for-one  stock split in
     the form of a 100% stock  dividend  (the "Stock  Split")  payable on May 5,
     1999 to  shareholders  of record on April 20, 1999,  subject to shareholder
     approval of the increase in authorized  shares (which was obtained on April
     20,  1999).  The dividend  was paid in Class A Special  Common Stock to the
     holders of Class A Common, Class A Special Common and Class B Common Stock.
     The average  number of shares  outstanding  and related  prices,  per share
     amounts,  share  conversions and stock option data have been  retroactively
     restated to reflect the Stock Split.  The Company's board of directors also
     eliminated the quarterly cash dividend of $.012 per share on all classes of
     its Common Stock.  The last  quarterly  cash dividend was paid on March 25,
     1999.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     New Accounting Pronouncement
     In June 1998, the Financial  Accounting Standards Board issued Statement of
     Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
     Instruments  and Hedging  Activities."  This statement,  which  establishes
     accounting and reporting  standards for derivatives and hedging activities,
     is effective  for fiscal  years  beginning  after June 15,  1999.  Upon the
     adoption of SFAS No. 133, all  derivatives are required to be recognized in
     the  statement of financial  position as either assets or  liabilities  and
     measured at fair value. The Company is currently  evaluating the impact the
     adoption of SFAS No. 133 will have on its financial position and results of
     operations.

     Earnings (Loss) for Common Stockholders Per Common Share
     Earnings  (loss) for common  stockholders  per common  share is computed by
     dividing net income (loss),  after deduction of preferred stock  dividends,
     when   applicable,   by  the  weighted  average  number  of  common  shares
     outstanding during the period on a basic and diluted basis.

     Put  options  sold by the  Company  on 5.5  million  shares  of its Class A
     Special Common stock (see Note 6) were outstanding  during the three months
     ended March 31, 1999 but were not  included in the  computation  of Diluted
     EPS as the options'  exercise  price was less than the average market price
     of the Company's Class A Special Common Stock during the period.

     For the three months ended March 31, 1998, the Company's  potential  common
     shares  of 86.6  million  shares  have an  antidilutive  effect on loss for
     common stockholders per common share and, therefore,  have not been used in
     determining the total weighted average number of common shares outstanding.

3.   SIGNIFICANT EVENTS

     AT&T Agreement
     On May 4,  1999,  the  Company  and AT&T  Corp.  ("AT&T")  entered  into an
     agreement  (the "AT&T  Agreement")  pursuant  to which the Company and AT&T
     agreed to exchange  various  cable  systems  (the  "System  Exchanges")  to
     improve each company's geographic clustering of systems. Under the terms of
     the AT&T Agreement,  the Company will pay AT&T  approximately  $3.4 billion
     (subject  to  adjustment  based on the  actual  number  of net  subscribers
     acquired  and the per  subscriber  price of  certain  subscribers)  for the
     approximately  750,000  net  subscribers  to be acquired as a result of the
     System Exchanges.  The Company will pay for the net subscribers acquired in
     connection  with the System  Exchanges  with  shares of AT&T  common  stock
     currently  owned  or  subsequently   acquired  by  the  Company  and  other
     securities or assets which would permit the System Exchanges to be tax-free
     to the extent possible.  The value of any currently owned AT&T common stock
     to be exchanged  will be  determined  based upon the average  trading price
     during the 20-day trading period beginning June 3, 1999.

                                   (Unaudited)

     Under the terms of the AT&T  Agreement,  the Company  also has an option to
     acquire from AT&T,  following  approximately three years,  additional cable
     systems with a total of between 1.0 million and 1.4 million subscribers for
     approximately  $4.8 billion to $6.7 billion  (subject to reduction  for any
     long-term debt and other  liabilities of the acquired cable  systems).  The
     Company will pay for these cable systems with shares of the Company's Class
     A Special  Common Stock (valued on the same basis as described in the prior
     paragraph)   and  other   securities  or  assets  which  would  permit  the
     acquisition  to be tax-free  (or if such result can not be  obtained,  with
     cash).

     Under the terms of the AT&T Agreement, the Company has also agreed to offer
     AT&T-branded  residential  wireline  telephony in its cable system markets,
     provided AT&T has concluded separate residential  telephony agreements with
     at least two other non-AT&T affiliated  multi-system cable operators.  AT&T
     has agreed to grant the Company the most  favorable  terms AT&T has reached
     with any of those or other multi-system cable operators.

     The  majority of the System  Exchanges  and the  exercise of the  Company's
     option to acquire the  additional  cable  systems are  contingent  upon the
     completion of AT&T's  acquisition of MediaOne (see Proposed  Acquisition of
     MediaOne  Group,  Inc.  below),  which is  expected  to close in the  first
     quarter of 2000,  subject to receipt of necessary  shareholder,  regulatory
     and  other  approvals.  There  can  be no  assurance,  however,  that  such
     acquisition will be consummated.

     Proposed Acquisition of MediaOne Group, Inc.
     On March 22,  1999,  the Company and  MediaOne  Group,  Inc.  ("MediaOne"),
     entered  into an  Agreement  and Plan of Merger  (the  "Merger  Agreement")
     pursuant  to which  MediaOne  was to be merged  with and into the  Company.
     Under the terms of the  Merger  Agreement,  MediaOne  could  terminate  the
     Merger  Agreement  under  certain  conditions,   provided  that  it  pay  a
     termination fee of $1.5 billion in cash to the Company.  On April 22, 1999,
     AT&T submitted an offer to purchase MediaOne.  On May 1, 1999, the MediaOne
     Board of Directors  notified the Company  that it had  determined  that the
     AT&T offer was superior to the Company's  offer.  On May 6, 1999,  MediaOne
     terminated  the  Merger   Agreement  and  MediaOne  paid  the  Company  the
     termination fee.

     Acquisition of Jones Intercable
     In May 1998,  the  Company  agreed to  purchase  from BCI  Telecom  Holding
     ("BTH") 6.4 million Class A Common Shares in Jones Intercable, Inc. ("Jones
     Intercable"),  and a 49%  interest  in the BTH  subsidiaries  which were to
     continue  to own BTH's  remaining  6.4 million  shares of Jones  Intercable
     Class A Common  Stock.  At the same  time,  the  Company  agreed to acquire
     approximately  2.9 million shares of Common Stock of Jones  Intercable (the
     "Control  Shares"),  if and when  acquired by BTH from  affiliates of Jones
     Intercable's controlling shareholder under an existing option (the "Control
     Option") to acquire such shares (which absent  extraordinary  circumstances
     would not have been  exercisable  until December 2001).  The Company was to
     purchase the remaining 51% of the BTH subsidiaries  when the Control Shares
     were acquired.  The Company,  BTH, Jones Intercable and Jones  Intercable's
     controlling  shareholder  agreed in August 1998 to  accelerate  the Control
     Option  to  permit  its  early  exercise  and  the  early  closing  of  the
     transactions with BTH. The transaction closed on April 7, 1999. The Company
     paid  $706.3  million in cash to acquire the 12.8  million  shares of Jones
     Intercable Class A Common Stock and the Control Shares.  After closing, the
     Company  controls  approximately  37% of the economic and 47% of the voting
     interest in Jones  Intercable.  In addition,  the Control Shares  represent
     shares  having  the  right  to  elect  approximately  75% of the  Board  of
     Directors of Jones  Intercable.  The  acquisition was funded with available
     cash and cash equivalents. Jones Intercable is a public company, which upon
     closing  of  certain  pending  transactions,   will  own  or  manage  cable
     operations serving approximately 1.0 million customers.

     Acquisition of Greater Philadelphia Cablevision
     In  February  1999,  the  Company  agreed to acquire  Greater  Philadelphia
     Cablevision, Inc, a subsidiary of Greater Media, Inc. that operates a cable
     system  serving   approximately   79,000   subscribers   in   Philadelphia,
     Pennsylvania.  The Company will issue  approximately  8.4 million shares of
     its  Class  A  Special  Common  Stock  to  complete  the  acquisition.  The
     acquisition is expected to close in the fourth quarter of 1999,  subject to
     receipt of all necessary regulatory and other approvals.

     Sale of Comcast Cellular
     In January  1999,  the Company  agreed to sell its  indirect  wholly  owned
     subsidiary, Comcast Cellular, to SBC Communications, Inc. for approximately
     $400 million in cash and the  assumption of  approximately  $1.3 billion of
     Comcast  Cellular  debt. As of March 31, 1999,  Comcast  Cellular  provides
     telephone  communications  services  pursuant  to  licenses  granted by the
     Federal  Communications  Commission to more than 862,000 subscribers in and
     around the City of  Philadelphia,  the State of Delaware and a  significant
     portion of the State of New  Jersey.  Revenues  for Comcast  Cellular  were
     $109.8 million and $105.4 million for the three months ended March 31, 1999
     and 1998,  respectively.  The sale of Comcast Cellular is expected to close
     in the second  quarter  of 1999  subject  to the  receipt of all  necessary
     regulatory and other approvals.

     Investment in Prime Communications
     In December 1998, the Company agreed to invest in Prime  Communications LLC
     ("Prime"),  a cable television operator with cable  communications  systems
     serving  approximately  430,000  subscribers.  During the fourth quarter of
     1998, the Company acquired a $50 million 12.75%  subordinated note due 2008
     from Prime. In addition, under the terms of the agreement, the Company will
     lend Prime  approximately  $735  million in the form of a 6% ten year note,
     expected to occur in the third quarter of 1999. In return, the Company will
     receive a  convertible  note giving the Company the right to acquire 90% of
     Prime.  The note  cannot be  converted  until the build out of  certain  of
     Prime's cable systems is complete and  regulatory  and other  approvals are
     obtained,  which is expected to occur in the third  quarter of 2002. If the
     note is converted,  the Company would assume  approximately $550 million of
     Prime debt.  The Company would have the option to acquire the remaining 10%
     interest in Prime for approximately  $82 million,  plus accrued interest at
     7% per annum.

     Equity Method
     The Company records its proportionate interests in the net income (loss) of
     substantially  all of its equity method  investees three months in arrears.
     The Company's recorded  investments  exceed its proportionate  interests in
     the book value of the  investees'  net assets by $81.3  million as of March
     31,  1999  (primarily  related  to the  Company's  investment  in The  Golf
     Channel).  Such excess is being  amortized to equity in net income or loss,
     primarily  over a period  of twenty  years,  which is  consistent  with the
     estimated lives of the underlying  assets. The original cost of investments
     accounted for under the equity  method  totaled  $203.9  million and $215.3
     million as of March 31, 1999 and December 31, 1998, respectively.

     Sprint PCS.  Effective  November 1998, in connection with the restructuring
     of Sprint PCS, the Company  accounts for its investment in Sprint PCS under
     the fair value method.

     Teleport.  In November 1997,  Teleport  issued shares of its Class A Common
     Stock.  As a result of the share issuance,  the Company  recognized a $59.6
     million increase in its  proportionate  share of Teleport's net assets as a
     gain from equity offering of affiliate for the three months ended March 31,
     1998. The Company recorded its proportionate share of Teleport's net assets
     one quarter in arrears. In July 1998, in connection with AT&T's acquisition
     of Teleport,  the Company  exchanged its interest in Teleport for shares of
     AT&T common stock.  As of March 31, 1999 and December 31, 1998, the Company
     has recorded its investment in AT&T at its estimated fair value.

     UK  Investees.  In October  1998,  the Company  exchanged  its  interest in
     Comcast UK Cable  Partners  Limited  ("Comcast UK Cable") for shares of NTL
     Incorporated  ("NTL")  common stock.  As of March 31, 1999 and December 31,
     1998,  the Company has recorded its investment in NTL at its estimated fair
     value.

     Other.  The Company's other equity investees  include  investments in cable
     communications and content  providers.  The Company does not consider these
     other equity  method  investments  to be  individually  significant  to its
     consolidated financial position, results of operations or liquidity.

     Fair Value Method
     The Company  holds  unrestricted  equity  investments  in certain  publicly
     traded  companies,  with an historical  cost  (including  $1.999 billion of
     pre-tax gains recognized  during 1998) of $2.682 billion and $2.555 billion
     as of March 31, 1999 and December 31, 1998,  respectively.  The Company has
     recorded these investments,  which are classified as available for sale, at
     their  estimated  fair values of $6.044  billion  and $4.170  billion as of
     March 31, 1999 and December 31, 1998, respectively.  The unrealized pre-tax
     gains as of March 31,  1999 and  December  31,  1998 of $3.362  billion and

     respectively.

     AT&T Acquisition of TCI
     In March 1999, AT&T merged with Tele-Communications, Inc. ("TCI") with AT&T
     as the surviving  corporation (the "AT&T/TCI Merger").  Upon closing of the
     AT&T/TCI Merger, the Company received  approximately 3.6 million shares (as
     adjusted for AT&T's 3-for-2 stock split in April 1999) of AT&T common stock
     in exchange for the  approximately 3.1 million shares of TCI Class A Common
     Stock  held by the  Company  and the  Company  received  approximately  3.6
     million  shares of Class A Liberty  Media  Group ("New  Liberty")  Tracking
     Shares for the approximately 2.3 million shares of TCI Ventures Group, Inc.
     ("TCI Ventures")  common stock and the  approximately 2.4 million shares of
     Liberty  Media  Group  ("Old  Liberty")  Class A Common  Stock  held by the
     Company. As a result of the exchange, the Company recognized a pre-tax gain
     of  $187.6   million   during  the  three  months  ended  March  31,  1999,
     representing  the  difference  between the fair value of the stock received
     and the Company's  basis in TCI and TCI Ventures.  Such gain is included in
     investment  (income)  expense  in  the  Company's  condensed   consolidated
     statement of operations and accumulated deficit.

     In March 1998, the Company sold call options  relating to its  unrestricted
     equity  investments  in TCI,  TCI  Ventures  and Old Liberty  common  stock
     (together,  the "TCI Stock") for $20.7  million.  Such call options  expire
     between  March and November  1999.  During the three months ended March 31,
     1999 and 1998, the Company  recorded  pre-tax  investment  expense of $51.4
     million and $14.6 million, respectively, related to changes in the value of
     the call options and settlement of the TCI and TCI Ventures call options.

     Impairment Losses
     During the three  months  ended  March 31,  1999,  the  Company  recorded a
     pre-tax  loss of $35.3  million on certain  of its  investments  based on a
     decline in value that was  considered  other than  temporary.  Such pre-tax
     loss is included in investment  (income) expense in the Company's condensed
     consolidated statement of operations and accumulated deficit.

5.   LONG-TERM DEBT

     PHONES
     In March 1999,  the Company  issued  13.05  million (as adjusted for AT&T's
     3-for-2   stock  split  in  April  1999)  3.35%   Exchangeable   Extendable
     Subordinated  Debentures  due 2029 (the  "PHONES")  for gross  proceeds  of
     $718.3  million.  The PHONES  mature on May 15,  2029,  unless  extended as
     described below. At maturity, holders of the PHONES are entitled to receive
     in cash an amount  equal to the higher of (a) the  principal  amount of the
     PHONES, or (b) the market value of AT&T common stock. If the current market
     value of AT&T common stock is greater than 150% of the principal  amount of
     the PHONES on May 15, 2029, the maturity will be extended to May 15, 2059.

     Prior to maturity,  each PHONES is exchangeable  at the holders option,  at
     any time after  March 11,  2000,  for an amount of cash equal to 95% of the
     market  value of AT&T  common  stock.  If the  maturity  of the  PHONES  is
     extended to 2059, the early exchange ratio will be increased to 100%. Prior
     to  maturity,  the  Company  may  redeem  all of the PHONES at a per PHONES
     premium (as adjusted for AT&T's  3-for-2  stock split in April 1999) of (a)
     $2.47687 if redeemed  prior to May 15, 2000, (b) $1.65125 if redeemed prior
     to May 15,  2001,  (c) $0.82563 if redeemed  prior to May 15, 2002,  or (d)
     zero if redeemed on or after May 15, 2002.

     Interest  on the PHONES is payable  quarterly  (subject  to deferral at the
     Company's option) equal to 1.75% per year of the original principal amount,
     plus the  amount of the  quarterly  cash  dividend  paid on a share of AT&T
     common stock (1.60% as of the issuance date).  The principal  amount of the
     PHONES  will be adjusted if AT&T  changes the  dividend  paid on its common
     stock or if there are  special  distributions  on or in respect of the AT&T
     common stock.

     The PHONES are unsecured, subordinated obligations ranking equally with all
     of  the  Company's   existing  and  future   subordinated  debt  and  trade
     obligations.

     The PHONES are being accounted for as an indexed debt instrument  since the
     maturity value is dependent  upon the fair value of AT&T common stock.  The
     Company's  investment in AT&T is accounted  for as an "available  for sale"
     security under SFAS No. 115, with changes in fair value being  reflected in
     accumulated other comprehensive income (see Note 4).

     Interest Rates
     As of March  31,  1999 and  December  31,  1998,  the  Company's  effective
     weighted  average interest rate on its long-term debt outstanding was 7.16%
     and 7.71%, respectively.

     Lines of Credit
     As of March 31, 1999, certain  subsidiaries of the Company had unused lines
     of credit of $913.5  million,  $313.5 million of which is restricted by the
     covenants of the related debt agreements and to subsidiary general purposes
     and dividend declaration.

6.   STOCKHOLDERS' EQUITY

     Repurchase Program
     In September  1998,  the Company  announced that its Board of Directors had
     authorized a market repurchase program (the "Repurchase  Program") pursuant
     to which  the  Company  may  purchase,  in the open  market  or in  private
     transactions  up  to  $500.0  million  of  its  outstanding  common  equity
     securities, subject to certain restrictions and market conditions. Based on
     the trade date for stock  repurchases,  during the three months ended March
     31, 1999,  the Company  repurchased  0.4 million shares of its common stock
     for aggregate  consideration  of $11.5 million  pursuant to the  Repurchase
     Program.  As part of the Repurchase Program, in September 1998, the Company
     sold put options on 5.5 million shares of its Class A Special Common Stock.
     The put  options  give the  holder  the right to  require  the  Company  to
     repurchase  such shares at  specified  prices on specific  dates during the
     period from April through  September  1999. The amount the Company would be
     obligated to pay to repurchase  such shares if all  outstanding put options
     were  exercised,  totaling  $111.2  million,  has  been  reclassified  to a
     temporary equity account in the Company's  condensed  consolidated  balance
     sheet as of March 31, 1999 and December 31, 1998.

     Comprehensive Income (Loss)
     Total comprehensive income (loss) for the three months ended March 31, 1999
     and 1998  was  $1.215  billion  and  ($6.7)  million,  respectively.  Total
     comprehensive  income (loss) includes net income (loss),  unrealized  gains
     (losses) on marketable  securities and foreign currency  translation  gains
     (losses) for the periods presented.

7.   STATEMENT OF CASH FLOWS - SUPPLEMENTAL INFORMATION

     The Company  made cash  payments  for  interest of $56.4  million and $60.4
     million   during  the  three   months   ended  March  31,  1999  and  1998,
     respectively.

     The Company made cash  payments for income taxes of $18.9 million and $14.9
     million   during  the  three   months   ended  March  31,  1999  and  1998,
     respectively.

8.   COMMITMENTS AND CONTINGENCIES

     The Company is subject to legal  proceedings  and claims which arise in the
     ordinary course of its business.  In the opinion of management,  the amount
     of ultimate  liability  with respect to these  actions will not  materially
     affect the  financial  position,  results of operations or liquidity of the
     Company.

(2)  Operating income before  depreciation and amortization is commonly referred
     to in the Company's  businesses as "operating  cash flow."  Operating  cash
     flow is a measure of a company's  ability to  generate  cash to service its
     obligations, including debt service obligations, and to finance capital and
     other  expenditures.  In part due to the  capital  intensive  nature of the
     Company's  businesses  and the  resulting  significant  level  of  non-cash
     depreciation  and amortization  expense,  operating cash flow is frequently
     used  as  one  of the  bases  for  comparing  businesses  in the  Company's
     industries,  although the Company's  measure of operating cash flow may not
     be comparable to similarly  titled measures of other  companies.  Operating
     cash flow does not purport to represent  net income or net cash provided by
     operating  activities,  as those terms are defined under generally accepted
     accounting  principles,  and should not be considered as an  alternative to
     such measurements as an indicator of the Company's performance.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

Overview

     We have  experienced  significant  growth  in  recent  years  both  through
strategic   acquisitions  and  growth  in  our  existing  businesses.   We  have
historically  met our cash  needs for  operations  through  our cash  flows from
operating   activities.   Cash   requirements   for   acquisitions  and  capital
expenditures  have been provided  through our financing  activities and sales of
investments,  as well as our existing  cash,  cash  equivalents  and  short-term
investments.

     In January  1999, we agreed to sell our indirect  wholly owned  subsidiary,
Comcast Cellular Corporation ("Comcast Cellular"),  to SBC Communications,  Inc.
for approximately  $400 million in cash and the assumption of approximately $1.3
billion of Comcast  Cellular  debt. We expect to recognize a pre-tax gain on the
sale of  approximately  $600  million.  We expect to  complete  this sale in the
second  quarter of 1999 if we receive  all the  necessary  regulatory  and other
approvals. The results of Comcast Cellular have been presented as a discontinued
operation in our condensed consolidated financial statements.

General Developments of Business

     See Note 3 to our condensed  consolidated  financial statements included in
Item 1.

Liquidity and Capital Resources

     The  cable   communications  and  the  electronic  retailing  industry  are
experiencing  increasing competition and rapid technological changes. Our future
results of operations will be affected by our ability to react to changes in the
competitive  environment  and by our  ability  to  implement  new  technologies.
However,  we  believe  that  competition  and  technological  changes  will  not
significantly affect our ability to obtain financing.

     We believe that we will be able to meet our current and long-term liquidity
and capital requirements,  including fixed charges,  through our cash flows from
operating activities,  existing cash, cash equivalents,  short-term investments,
lines of credit and other external financing.

     Cash, Cash Equivalents and Short-term Investments

     We  have  traditionally   maintained   significant  levels  of  cash,  cash
equivalents  and  short-term   investments  to  meet  our  short-term  liquidity
requirements.  Our cash  equivalents and short-term  investments are recorded at
fair value.  Cash, cash  equivalents and short-term  investments as of March 31,
1999 were $6.527 billion.  As of March 31, 1999, our cash, cash  equivalents and
short-term  investments  include $4.920 billion of our investments in AT&T Corp.
("AT&T"),  Sprint PCS, NTL  Incorporated  ("NTL") and Liberty  Media Group ("New
Liberty")  (see  Note  4 to  our  condensed  consolidated  financial  statements
included  in Item 1). As of March 31,  1999,  $346.9  million of our cash,  cash
equivalents  and  short-term  investments  is restricted to use by  subsidiaries
under contractual or other arrangements.

     Investments

     See  Notes  3 and 4 to  our  condensed  consolidated  financial  statements
included in Item 1.

     We do not have any significant contractual funding commitments with respect
to any of our investments.  However, to the extent we do not fund our investees'
capital calls, we expose  ourselves to dilution of our ownership  interests.  We
continually  evaluate  our  existing  investments,  as  well  as new  investment
opportunities.

     Financing
     See  Notes  5 and 6 to  our  condensed  consolidated  financial  statements
included in Item 1.

     As of March 31, 1999 and December 31, 1998, our long-term  debt,  including
current portion, was $6.291 billion and $5.578 billion,  respectively,  of which
16.9% and 18.0%, respectively, was at variable rates.

     We may from time to time,  depending on certain  factors  including  market
conditions, make optional repayments on our debt obligations,  which may include
open market repurchases of our outstanding public notes and debentures.

     Year 2000 Issue

     The Year 2000 Issue is the result of computer  programs being written using
two  digits  rather  than four to define  the  applicable  year.  Certain of our
computer programs that have  date-sensitive  software may recognize a date using
"00" as the year 1900 rather than the year 2000 (the "Year 2000 Issue"). If this
situation   occurs,   the  potential  exists  for  computer  system  failure  or
miscalculations   by  computer   programs,   which  could  cause  disruption  of
operations.

     We are in the process of evaluating  and  addressing the impact of the Year
2000 Issue on our  operations  to ensure  that our  information  technology  and
business  systems  recognize  calendar Year 2000. We are utilizing both internal
and external resources in implementing our Year 2000 program,  which consists of
the following phases:

     o    Assessment  Phase.   Structured   evaluation,   including  a  detailed
          inventory  outlining  the impact  that the Year 2000 Issue may have on
          current operations.

     o    Detailed Planning Phase.  Establishment of priorities,  development of
          specific  action  steps and  allocation  of  resources  to address the
          issues identified in the Assessment Phase.

     o    Conversion Phase. Implementation of the necessary system modifications
          as outlined in the Detailed Planning Phase.

     o    Testing Phase.  Verification that the modifications implemented in the
          Conversion  Phase will be  successful in resolving the Year 2000 Issue
          so that all inventory items will function properly,  both individually
          and on an integrated basis.

     o    Implementation  Phase.  Final roll-out of fully tested components into
          an operational unit.

     Based on an  inventory  conducted  in  1997,  we have  identified  computer
systems that will require modification or replacement so that they will properly
utilize dates beyond December 31, 1999. Many of our critical systems are new and
are already Year 2000 compliant as a result of the recent rebuild of many of our
cable communications systems. In addition, we have initiated communications with
all of our significant software suppliers and service bureaus to determine their
plans for remediating the Year 2000 Issue in their software which we use or rely
upon.

     As of  March  31,  1999,  we are in the  Testing  Phase  of our  Year  2000
remediation  program and have entered the  Implementation  Phase with respect to
certain  of  our  key  systems.   Through  March  31,  1999,  we  have  incurred
approximately $6.0 million in connection with our Year 2000 remediation program.
We estimate that we will incur between  approximately $10 million to $16 million
of additional  expense  through  December 1999 in connection  with our Year 2000
remediation  program. Our estimate to complete the remediation plan includes the
estimated time  associated  with  mitigating the Year 2000 Issue for third party
software. However, there can be no guarantee that the systems of other companies
on which we rely will be  converted  on a timely  basis,  or that a  failure  to
convert by another company would not have a material adverse effect on us.

     Our  management  will continue to  periodically  report the progress of our
Year 2000 remediation  program to the Audit Committee of our Board of Directors.
We plan to complete the Year 2000  mitigation by the third quarter of 1999.  Our
management has investigated and may consider potential  contingency plans in the
event that our Year 2000 remediation program is not completed by that date.

     The costs of the project and the date on which we plan to complete the Year
2000 modifications and replacements are based on our best estimates,  which were
derived using assumptions of future events including the continued  availability
of resources and the  reliability of third party  modification  plans.  However,
there can be no  guarantee  that these  estimates  will be  achieved  and actual
results  could differ  materially  from those plans.  Specific  factors that may
cause  such  material   differences   include,  but  are  not  limited  to,  the
availability  and cost of personnel with  appropriate  necessary  skills and the
ability  to  locate  and  correct  all  relevant   computer   code  and  similar
uncertainties.

     We believe that with  modifications to existing software and conversions to
new  software,  the  Year  2000  Issue  can  be  mitigated.   However,  if  such
modifications  and  conversions  are not made,  or are not  completed  within an
adequate time frame, the Year 2000 Issue could have a material adverse impact on
our operations.

Statement of Cash Flows

     Cash and cash  equivalents  increased  $678.0  million as of March 31, 1999
from December 31, 1998. The increase in cash and cash equivalents  resulted from
cash flows from operating, financing and investing activities
which are explained below.

     Net cash  provided  by  operating  activities  from  continuing  operations
amounted  to  $300.3  million  for the three  months  ended  March 31,  1999 due
principally to our operating income before  depreciation  and amortization  (see
"Results  of  Operations")  and  changes in  working  capital as a result of the
timing of receipts and disbursements.

     Net cash provided by financing activities from continuing operations, which
includes  borrowings  and  repayments  of  debt,  as well as the  issuances  and
repurchases  of our equity  securities,  was $685.0 million for the three months
ended March 31, 1999.  During the three months ended March 31, 1999,we  borrowed
$778.3  million,  consisting  primarily of $718.3 million of 3.35%  Exchangeable
Extendable  Subordinated  Debentures due 2029 (the  "PHONES").  During the three
months ended March 31, 1999, we repaid $66.4  million of our long-term  debt. In
addition,  during the three months ended March 31, 1999, we had net  repurchases
of $3.5 million of our common  stock and we paid cash  dividends of $9.0 million
on our common stock and Series A Preferred  Stock.  Deferred  financing costs of
$14.4  million  were  incurred  during the three  months ended March 31, 1999 in
connection with the issuance of the PHONES.

     Net cash used in investing activities from continuing operations was $307.3
million for the three months  ended March 31,  1999.  Net cash used in investing
activities  includes  investments of $116.4  million,  capital  expenditures  of
$122.4 million, additions to deferred charges of $78.6 million and net purchases
of short-term  investments  of $40.6  million,  offset by proceeds from sales of
investments of $50.7 million.

(1)  Operating income before  depreciation and amortization is commonly referred
     to in our  businesses as "operating  cash flow."  Operating  cash flow is a
     measure of a company's ability to generate cash to service its obligations,
     including  debt  service  obligations,  and to  finance  capital  and other
     expenditures. In part due to the capital intensive nature of our businesses
     and the resulting  significant level of non-cash  depreciation  expense and
     amortization expense,  operating cash flow is frequently used as one of the
     bases for comparing  businesses in our industries,  although our measure of
     operating cash flow may not be comparable to similarly  titled  measures of
     other  companies.  Operating  cash flow does not purport to  represent  net
     income or net cash  provided by  operating  activities,  as those terms are
     defined under generally accepted accounting  principles,  and should not be
     considered as an  alternative to such  measurements  as an indicator of our
     performance.  See  "Statement  of Cash Flows" above for a discussion of net
     cash provided by operating activities.

     Of the $63.6 million  increase in service income for the three month period
from  1998  to  1999,  $13.4  million  is  attributable  to the  effects  of the
acquisitions of cable  communications  systems,  $6.7 million is attributable to
subscriber  growth,  $24.9 million relates to changes in rates,  $5.0 million is
attributable to growth in cable  advertising  sales and $13.6 million relates to
other product offerings (e.g., digital cable, high speed data services, etc.).

     Of  the  $32.5  million  increase  in  operating,   selling,   general  and
administrative  expenses  for the three  month  period  from 1998 to 1999,  $7.3
million  is   attributable   to  the  effects  of  the   acquisitions  of  cable
communications systems, $9.5 million is attributable to an increase in the costs
of cable  programming  as a result of  changes in rates,  subscriber  growth and
additional  channel  offerings,  $1.3  million  is  attributable  to  growth  in
advertising sales and $14.4 million results from increases in the cost of labor,
other volume related expenses and costs  associated with new product  offerings.
We anticipate that the cost of cable  programming will increase in the future as
cable  programming  rates increase and additional  sources of cable  programming
become available.

</TABLE>

     The increase in net sales from  electronic  retailing of $105.0 million for
the three month  period  from 1998 to 1999 is due to the effects of 4.2%,  10.8%
and 42.2% increases in the average number of homes receiving QVC services in the
United States ("US"), United Kingdom ("UK") and Germany, respectively, and 8.6%,
18.3% and  87.7%  increases  in net  sales  per home in the US, UK and  Germany,
respectively.

     The  increase in cost of goods sold is  primarily  related to the growth in
net sales.  The  increase in gross margin is a result of a slight shift in sales
mix to higher margin products.

     Of  the  $11.1  million  increase  in  operating,   selling,   general  and
administrative  expenses  for the three  month  period  from 1998 to 1999,  $8.6
million is attributable to higher variable costs associated with the increase in
sales volume. The remaining increase is attributable to personnel and facilities
based  costs  associated  with  Studio  Park,  QVC's   production,   studio  and
administrative facility and expansion in the UK and Germany.

                             -----------------------

     Consolidated Analysis

     The  effects of our recent  acquisitions,  as well as  increased  levels of
capital  expenditures,  were to increase our revenues and expenses  resulting in
increases in our operating  income before  depreciation  and  amortization.  The
decreases in depreciation expense,  amortization  expense,  interest expense and
other income for the three month period from 1998 to 1999 was  primarily  due to
the  effects of the sale of  Comcast  UK Cable  Partners  Limited  ("Comcast  UK
Cable"),  a consolidated  subsidiary of ours, in October 1998. In addition,  our
equity in net losses of affiliates has decreased  principally as a result of the
restructuring of Sprint PCS in November 1998.

     Interest Expense

     We anticipate that, for the foreseeable future,  interest expense will be a
significant cost to us and will have a significant adverse effect on our ability
to realize  net  earnings.  We believe we will  continue  to be able to meet our
obligations  through  our  ability  both to  generate  operating  income  before
depreciation and amortization and to obtain external financing.

     Investment (Income) Expense

     In March 1999, AT&T merged with TeleCommunications,  Inc. ("TCI") with AT&T
as the  surviving  corporation  (the  "AT&T/TCI  Merger").  Upon  closing of the
AT&T/TCI Merger,  we received  approximately 3.6 million shares (as adjusted for
AT&T's  3-for-2  stock split in April 1999) of AT&T common stock in exchange for
the  approximately 3.1 million shares of TCI Class A Common Stock held by us and
we received  approximately  3.6 million  shares of New Liberty  Class A Tracking
Shares for the  approximately  2.3 million  shares of TCI Ventures  Group,  Inc.
("TCI  Ventures")  common  stock and the  approximately  2.4  million  shares of
Liberty Media Group ("Old Liberty") Class A Common Stock

                          QUARTER ENDED MARCH 31, 1999


held by us. As a result of the exchange,  we recognized a pre-tax gain of $187.6
million  during  the  three  months  ended  March  31,  1999,  representing  the
difference  between the fair value of the AT&T stock  received  and our basis in
TCI and TCI Ventures.

     In March 1998,  we sold call options  relating to our  unrestricted  equity
investments in TCI, TCI Ventures and Old Liberty common stock for $20.7 million.
Such call  options  expire  between  March and November  1999.  During the three
months ended March 31, 1999 and 1998, we recorded pre-tax  investment expense of
$51.4 million and $14.6 million,  respectively,  related to changes in the value
of the call options and settlement of the TCI and TCI Ventures call options.

     During the three months ended March 31, 1999, we recorded a pre-tax loss of
$35.3 million on certain of our investments based on a decline in value that was
considered other than temporary.

     Gain From Equity Offering of Affiliate

     In November 1997, Teleport  Communications  Group Inc.  ("Teleport") issued
shares  of its Class A Common  Stock.  As a result  of the  stock  issuance,  we
recognized a $59.6 million increase in our proportionate share of Teleport's net
assets as a gain from equity  offering of  affiliate  for the three months ended
March 31, 1998. We recorded our proportionate share of Teleport's net losses one
quarter in arrears.

     Income Tax Expense

     The $81.0 million increase in income tax expense for the three month period
from 1998 to 1999 is  primarily  the  result of the  effects  of  changes in our
income before taxes and minority interest, and non-deductible foreign losses and
non-deductible equity in net losses of affiliates.

     Minority Interest

     The $32.5 million increase in minority interest expense for the three month
period from 1998 to 1999 is primarily attributable to the effects of the sale of
Comcast  UK Cable in  October  1998 and the  increase  in QVC net income for the
three months ended March 31, 1999 as compared to the prior year period.

     For the three  months  ended March 31,  1999 and 1998,  our  earnings  from
continuing  operations (net income (loss) from continuing operations plus income
tax  expense  (benefit),  equity in net  (income)  losses of  affiliates,  fixed
charges  (interest  expense) and  extraordinary  items) were $299.3  million and
$187.3  million,  respectively.  Such  earnings were adequate to cover our fixed
charges of $111.2  million and $120.4  million for the three  months ended March
31, 1999 and 1998, respectively. Fixed charges include non-cash interest expense
of $0.5 million and $14.4  million for the three months ended March 31, 1999 and
1998, respectively.

     We  believe  that  any  losses  incurred  in  the  future  by us  will  not
significantly  affect the performance of our normal business  activities because
of our existing cash, cash equivalents and short-term  investments,  our ability
to generate  operating  income  before  depreciation  and  amortization  and our
ability to obtain external financing.

     We believe that our operations are not materially affected by inflation.
