     This  Quarterly  Report on Form 10-Q is for the three months ended June 30,
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.

     Basis of Presentation
     The condensed  consolidated  balance sheet as of December 31, 1998 has been

     condensed  consolidated  balance  sheet as of June 30, 1999,  the condensed
     consolidated  statements of operations and accumulated  deficit for the six
     and  three  months  ended  June  30,  1999  and  1998  and  the   condensed
     consolidated statement of cash flows for the six months ended June 30, 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

     adjustments) necessary to present fairly the financial position, results of
     operations and cash flows as of June 30, 1999 and for all periods presented
     have been made.

     annual financial  statements prepared in accordance with generally accepted
     accounting  principles  have been  condensed  or omitted.  These  condensed

     31, 1998 Annual Report on Form 10-K filed with the  Securities and Exchange
     Commission  (the "SEC").  The results of  operations  for the periods ended
     June 30, 1999 are not necessarily  indicative of operating  results for the

     Transactions" (see Note 3).

     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 (the "FASB") issued
     Statement of Financial  Accounting  Standards ("SFAS") No. 133, "Accounting
     for  Derivative   Instruments  and  Hedging   Activities."  This  statement
     establishes  the accounting  and reporting  standards for  derivatives  and
     hedging  activity.  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.  In July 1999, the FASB
     issued SFAS No. 137,  "Accounting  for Derivative  Instruments  and Hedging
     Activities - Deferral of the Effective  Date of FASB Statement No. 133 - an
     amendment of FASB  Statement  No. 133"  deferring  the  effective  date for
     implementation  of SFAS No. 133 to fiscal  years  beginning  after June 15,
     2000.  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 a weighted  average 4.8 million  shares
     and 4.2 million shares,  respectively,  of its Class A Special Common stock
     (see Note 6) were  outstanding  during the six and three  months ended June
     30,  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 periods.

     For the six and three months ended June 30, 1998,  the Company's  potential
     common shares of 94.0 million shares and 94.0 million shares, respectively,
     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.

     Certain  reclassifications  have  been  made to the  prior  year  condensed
     consolidated  financial statements to conform to those classifications used

3.   SIGNIFICANT EVENTS

     Sale of Comcast Cellular
     In July 1999,  the Company  completed  the sale of Comcast  Cellular to SBC
     Communications,  Inc.  for  approximately  $360  million  in  cash  and the
     assumption of $1.315 billion of Comcast  Cellular debt. The Company expects
     to recognize a gain in the third quarter of approximately $350 million, net
     of income tax  expense.  Such gain will be reflected as gain on disposal of
     discontinued  operations in the Company's condensed  consolidated statement
     of operations and accumulated  deficit.  Revenues for Comcast Cellular were
     $241.6  million and $221.3  million for the six months  ended June 30, 1999
     and 1998, respectively.

     Acquisition of Greater Philadelphia Cablevision
     On June  30,  1999,  the  Company  completed  the  acquisition  of  Greater
     Philadelphia  Cablevision, Inc. ("Greater  Philadelphia"),  a subsidiary of
     Greater  Media,  Inc.  that operates a cable system  serving  approximately
     79,000 subscribers in Philadelphia,  Pennsylvania, by issuing approximately
     8.5 million shares of its Class A Special

     Common Stock with a value of $291.7 million based upon the average  closing
     price of the Company's  Class A Special  Common Stock for a ten-day  period
     before and after the  announcement of the transaction in February 1999. The
     acquisition was accounted for under the purchase  method of accounting,  as
     such, the operating  results of Greater  Philadelphia have been included in
     the  accompanying   condensed  consolidated  statement  of  operations  and
     accumulated  deficit  from the  acquisition  date.  The  allocation  of the
     purchase  price to the assets and  liabilities of Greater  Philadelphia  is
     preliminary  pending  a final  appraisal.  As the  consideration  given  in
     exchange  for  Greater  Philadelphia  was shares of the  Company's  Class A
     Special  Common  Stock,  the  Greater   Philadelphia   acquisition  had  no
     significant  impact on the Company's  condensed  consolidated  statement of
     cash flows.

     Adelphia Agreement
     In May  1999,  the  Company  and Jones  Intercable,  Inc.,  a  consolidated
     subsidiary  of the Company,  ("Jones  Intercable" - see  "Acquisition  of a
     Controlling  Interest in Jones Intercable" below) entered into an agreement
     (the "Adelphia  Agreement") to exchange certain cable systems with Adelphia
     Communications ("Adelphia"). Under the terms of the Adelphia Agreement, the
     Company and Jones Intercable,  in the aggregate, will receive approximately
     464,000 cable subscribers from Adelphia. In exchange, Adelphia will receive
     current systems owned by the Company and Jones Intercable  serving,  in the
     aggregate,  approximately 440,000 subscribers.  All of the systems involved
     in the transactions  will be valued based upon independent  appraisals with
     any difference in relative value to be funded with cash or additional cable
     systems.  The  system  exchanges  are  subject  to  customary  closing  and
     regulatory approvals and are expected to close by mid-2000.

     AT&T Agreement
     In May 1999, the Company and AT&T Corp.  ("AT&T") entered into an agreement
     (the "AT&T  Agreement") to exchange various cable systems (the "AT&T System
     Exchanges").  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 AT&T System Exchanges.  The Company will pay for the net
     subscribers  acquired in  connection  with the AT&T 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 AT&T 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 $54.41 per share,  based
     upon the average  trading price during the 20-day trading period  beginning
     June 3, 1999.

     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 AT&T 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 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.
     In March 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. In April 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. The  termination  fee was recorded to other income in the
     Company's  condensed  consolidated  statement of operations and accumulated
     deficit,  net of transaction costs, for the six and three months ended June
     30, 1999.

     Acquisition of a Controlling Interest in 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,  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.  On June 29, 1999, the Company
     purchased an  additional  1.0 million  shares of Jones  Intercable  Class A
     Common Stock for $50.0 million  through a private  transaction.  As of June
     30,  1999,  the Company  controls  39.6% of the  economic  and 48.3% 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 share  acquisitions were funded with
     available cash and cash equivalents.  Jones Intercable is a public company,
     which owns cable operations  serving  approximately 1.0 million  customers.
     The  acquisition was accounted for under the purchase method of accounting,
     as such, the operating  results of Jones  Intercable  have been included in
     the  accompanying   condensed  consolidated  statement  of  operations  and
     accumulated  deficit  from the  acquisition  date.  The  allocation  of the
     purchase  price  to the  assets  and  liabilities  of Jones  Intercable  is
     preliminary pending a final appraisal.

     On August 9, 1999, the Company announced its intention to commence an offer
     to exchange  1.4 shares of its Class A Special  Common Stock for each share
     of Class A Common Stock or Common Stock of Jones  Intercable  for up to 79%
     of the combined number of shares of Jones  Intercable  Class A Common Stock
     and Common Stock outstanding (subject to certain terms and conditions to be
     contained  in  the  offer   documents).   The  offer  would  commence  upon
     registration of the Company's Class A Special Common Stock to be offered in
     the  exchange  offer with the SEC  pursuant  to an  effective  registration
     statement.

     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, in July 1999 the
     Company issued to Prime a $735 million 6% ten year convertible note, giving
     the Company the right to convert the note 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 close no later than 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
     certain of its equity method investees in arrears.  The Company's  recorded
     investments  exceed its  proportionate  interests  in the book value of the
     investees'  net  assets by $80.5  million  as of June 30,  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 $233.5 million and $215.3 million as of June 30, 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 six months ended June 30,
     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 June 30, 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 June 30, 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 $2.706 billion and $2.555 billion
     as of June 30, 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 $6.882 billion and $4.170 billion as of June
     30, 1999 and December 31, 1998, respectively.  The unrealized pre-tax gains
     as of June 30,  1999 and  December  31,  1998 of $4.176  billion and $1.615
     billion,  respectively,  have  been  reported  in the  Company's  condensed
     consolidated   balance   sheet  as  a  component   of   accumulated   other
     comprehensive  income, net of related deferred income tax expense of $1.462
     billion and $565.1 million, 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 six months ended June 30, 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 six and three months ended June
     30,  1999 and 1998,  the  Company  recorded  investment  expense  of $100.8
     million,  $40.2  million,  $49.4 million and $25.6  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 six and three months ended June 30, 1999,  the Company  recorded
     pre-tax losses of $35.5 million and $0.2 million,  respectively, on certain
     of its  investments  based on a decline in value that was considered  other
     than temporary.  Such losses are 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 8.7 million 3.35% Exchangeable Extendable
     Subordinated  Debentures  due 2029 (the  "PHONES")  for gross  proceeds  of
     $718.3 million. 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.

     The PHONES are being accounted for as an indexed debt  instrument,  at June
     30, 1999, 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).

     In July 1999, the Company  redeemed all $718.3 million  principal amount of
     its PHONES.  The Company redeemed the PHONES due to its recently  announced
     transaction   with  AT&T  in  which  it  intends  to  use  AT&T  shares  as
     consideration  for the purchase of cable  systems  from AT&T in  accordance
     with  the AT&T  Agreement  (see  Note 3).  In  connection  with the  PHONES
     redemption, the Company incurred debt extinguishment costs of $32.3 million
     and  wrote-off   unamortized  debt  acquisition  costs  of  $14.6  million,
     resulting in an extraordinary loss, net of tax, of $30.5 million which will
     be recorded in the third quarter of 1999.

     Interest Rates
     As of June 30, 1999 and December 31, 1998, the Company's effective weighted
     average  interest  rate on its  long-term  debt  outstanding  was 7.15% and
     7.71%, respectively.

     Lines of Credit
     As of June 30, 1999,  certain  subsidiaries of the Company had unused lines
     of credit of $1.187  billion,  $586.5 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 six months ended June 30,
     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.
     During the six and three months ended June 30, 1999,  put options  covering
     3.0  million  shares  expired  unexercised.  Upon  expiration,  the Company
     reclassified $60.7 million,  the amount it would have been obligated to pay
     to repurchase such shares had the put options been  exercised,  from common
     equity  put  options  to  additional  capital  in the  Company's  condensed
     consolidated  balance sheet.  The remaining 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 July through  September  1999. The
     amount the Company would be obligated to pay to  repurchase  such shares if
     all  outstanding  put options were  exercised,  totaling  $50.5 million and
     $111.2 million,  respectively,  has been reclassified to a temporary equity
     account in the Company's  condensed  consolidated  balance sheet as of June
     30, 1999 and December 31, 1998.

     Series A Preferred Stock Conversion
     In July 1999,  the Company  exercised its right to convert all 6,370 shares
     of its Series A Preferred  Stock into  approximately  2.7 million shares of
     its Class A Special Common Stock.

     Comprehensive Income (Loss)
     Total  comprehensive  income (loss) for the six and three months ended June
     30, 1999 and 1998 was $2.573 billion,  ($10.5) million,  $1.358 billion and
     ($3.8) 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.

(a)  Operating  income (loss) 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 is the primary basis used by the Company's  management to measure
     the operating  performance of its businesses.  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 July  1999,  we  completed  the  sale of  Comcast  Cellular  Corporation
("Comcast Cellular") to SBC Communications,  Inc. for approximately $360 million
in cash, subject to customary closing adjustments,  and the assumption of $1.315
billion of Comcast  Cellular  debt.  We expect to  recognize a gain in the third
quarter of approximately $350 million,  net of income tax expense. The gain will
be reflected as gain on disposal of  discontinued  operations  in our  condensed
consolidated statement of operations and accumulated deficit.

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 June 30,
1999 were $7.929 billion.  As of June 30, 1999, our cash,  cash  equivalents and
short-term  investments  include $5.634 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 June 30,  1999,  $316.6  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 June 30, 1999 and December 31, 1998,  our long-term  debt,  including
current portion, was $7.843 billion and $5.578 billion,  respectively,  of which
20.5% 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.

     Equity Price Risk

     In  March  1999,  we  issued  8.7  million  3.35%  Exchangeable  Extendable
Subordinated  Debentures  due 2029 (the  "PHONES") for gross  proceeds of $718.3
million.  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. We accounted for the PHONES

                                       16

                           QUARTER ENDED JUNE 30, 1999


as an indexed debt  instrument,  at June 30, 1999,  since the maturity  value is
dependent  upon the fair value of AT&T common  stock.  In July 1999, we redeemed
all the PHONES and  incurred  debt  extinguishment  costs of $32.3  million  and
wrote-off  unamortized debt acquisition costs of $14.6 million,  resulting in an
extraordinary  loss,  net of tax, of $30.5 million which will be recorded in the
third quarter of 1999.

     In June 1999,  we entered  into  costless  collar  agreements  (the "Equity
Collars")  covering  $483.7  million  notional  amount of investment  securities
accounted  for at fair  value.  The Equity  Collars  limit our  exposure  to and
benefits from price fluctuations in the underlying equity securities. The Equity
Collars mature in 2001. As we account for the Equity Collars as a hedge, changes
in the value of the Equity  Collars are  substantially  offset by changes in the
value of the underlying  investment  securities which are also  marked-to-market
through  accumulated other  comprehensive  income in our condensed  consolidated
balance sheet.

     Interest Rate Risk

     From January 1, 1999 through August 13, 1999, we have entered into interest
rate exchange  agreements  ("Swaps") with an aggregate notional amount of $300.0
million  and as part of our  acquisition  of a  controlling  interest  in  Jones
Intercable,  Inc. ("Jones Intercable") (see Note 3 to our condensed consolidated
financial  statements included in Item 1), we acquired  Swaps with an  aggregate
notional  amount of $400.0 million.  Swaps with an aggregate  notional amount of
$350.0  million  either were  terminated or expired from January 1, 1999 through
August 13, 1999. As of August 13, 1999, we have Swaps with an aggregate notional
amount of $1.412  billion  having an  average  pay rate of 5.93% and an  average
receive rate of 5.93%.

     Year 2000 Readiness Disclosures

     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 June 30,  1999,  except for Jones  Intercable,  we are in the Testing
Phase and the  Implementation  Phase of our Year 2000  remediation  program with
respect to  certain of our key  systems.  For Jones  Intercable,  as of June 30,
1999,  we are in the  Conversion  Phase and the  Testing  Phase of our Year 2000
remediation program with respect to certain of our key systems. Through June 30,
1999, we have incurred approximately $9

million in connection with our Year 2000 remediation  program.  We estimate that
we will incur  between  approximately  $7 million to $13  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 end of the third quarter of
1999,  except for Jones Intercable which will be completed in November 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 $1.323 billion as of June 30, 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  $1.971  billion  for the six  months  ended  June  30,  1999,  due
principally to the effects of the receipt of the $1.5 billion termination fee in
May 1999 from MediaOne Group, Inc., our acquisition of a controlling interest in
Jones  Intercable  in  April  1999  (see  Note 3 to our  condensed  consolidated
financial  statements  included in Item 1),  increases in 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 $733.0  million  for the six months
ended June 30,  1999.  During the six months  ended June 30,  1999,  we borrowed
$912.6  million,  consisting  primarily  of $718.3  million of PHONES and $193.5
million under revolving lines of credit held by our subsidiaries. During the six
months ended June 30, 1999, we repaid $152.8  million of our long-term  debt. In
addition,  during the six months  ended June 30, 1999,  we had net  issuances of
$0.2 million of our common  stock and we paid cash  dividends of $9.4 million on
our common stock and Series A Preferred Stock. Deferred financing costs of $14.6
million were  incurred  during the six months  ended June 30, 1999  primarily in
connection with the issuance of the PHONES.

     Net cash used in investing activities from continuing operations was $1.381
billion  for the six months  ended  June 30,  1999.  Net cash used in  investing
activities  includes  acquisitions,  net of cash  acquired  of  $708.0  million,
consisting  primarily  of our  acquisition  of a  controlling  interest in Jones
Intercable,  investments  of  $196.2  million,  capital  expenditures  of $326.4
million,  additions to deferred  charges of $121.7  million and net purchases of
short-term  investments of $83.3  million,  offset by proceeds from sales of and
distributions from investments of $54.3 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 is the  primary  basis  used by our
     management  to  measure  the  operating   performance  of  our  businesses.
     Operating  cash flow does not purport to  represent  net income or net cash
     provided by operating

a  result  of  changes  in  rates,  subscriber  growth  and  additional  channel

increase  in the  future as cable  programming  rates  increase  and  additional
sources of cable programming become available.

     The increase in net sales from  electronic  retailing of $207.5 million for
the six month period from 1998 to 1999 is due to the effects of 3.8%,  11.3% and
40.1%  increases in the average  number of homes  receiving  QVC services in the
United States ("US"), United Kingdom ("UK") and Germany, respectively, and 9.7%,
12.0% and  98.6%  increases  in net  sales  per home in the US, UK and  Germany,
respectively.  The  increase in net sales from  electronic  retailing  of $102.5
million  for the three  month  period from 1998 to 1999 is due to the effects of
3.4%,  11.7% and 38.0%  increases in the average  number of homes  receiving QVC
services in the US, UK and  Germany,  respectively,  and 10.8%,  6.4% and 109.2%
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 respective  $26.1 million and $14.9 million  increases in operating,
selling, general and administrative expenses for the six and three month periods
from 1998 to 1999,  $17.8  million and $9.2 million are  attributable  to higher
variable  costs  associated  with the increase in sales  volume.  The  remaining
increases are  attributable  to higher  personnel costs to support the increased
sales volume in the US, 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
increases in depreciation expense, amortization expense and interest expense for
the six and three month

periods from 1998 to 1999 are primarily due to the effects of our acquisition of
a controlling  interest in Jones Intercable on April 7, 1999,  offset in part by
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

     The $17.5 million and $26.7 million  increases in interest  expense for the
six and three month  periods from 1998 to 1999 are  primarily due to the effects
of our  acquisition  of a  controlling  interest  in  Jones  Intercable  and the
issuance of the 6.20% nonrecourse notes issued by Comcast Cable  Communications,
Inc.  ("Comcast  Cable"),  a wholly owned  subsidiary of ours, in November 1998,
offset in part by the effects of the sale of Comcast UK Cable in October 1998.

     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 held by us. As a result
of the exchange,  we recognized a pre-tax gain of $187.6  million during the six
months ended June 30, 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 six and
three months  ended June 30, 1999 and 1998,  we recorded  investment  expense of
$100.8 million,  $40.2 million,  $49.4 million and $25.6 million,  respectively,
related to changes in the value of the call  options and  settlement  of the TCI
and TCI Ventures call options.

     During the six months ended June 30, 1999,  we recorded  pre-tax  losses of
$35.5 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 six months ended June
30,  1998.  We recorded our  proportionate  share of  Teleport's  net losses one
quarter in arrears.

     Other Income

     The $1.427 billion and $1.429 billion increases in other income for the six
and three month  periods  from 1998 to 1999 are  primarily  attributable  to the
receipt of the $1.5 billion MediaOne  termination fee, net of transaction costs,
in May 1999.

     Income Tax Expense

     The $714.4 million and $633.3  million  increases in income tax expense for
the six and three month  periods from 1998 to 1999 are  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 changes in minority interest income for the six and three month periods
from  1998 to 1999 are  attributable  to the  effects  of our  acquisition  of a
controlling  interest in Jones  Intercable in April 1999, the sale of Comcast UK
Cable in October 1998 and to changes in the net income or loss of our other less
than 100% owned consolidated subsidiaries.

                           QUARTER ENDED JUNE 30, 1999


     For the six and three  months  ended June 30, 1999 and 1998,  our  earnings
from continuing operations (income (loss) from continuing operations plus income
tax  expense,  equity  in net  losses of  affiliates,  fixed  charges  (interest
expense) and extraordinary  items) were $1.908 billion,  $334.5 million,  $1.609
billion and $147.1 million,  respectively.  Such earnings were adequate to cover
our fixed charges of $254.7 million,  $237.2 million,  $143.5 million and $116.8
million for the six and three months ended June 30, 1999 and 1998, respectively.
Fixed charges include non-cash interest expense of $1.8 million,  $26.0 million,
$1.3 million and $11.6  million for the six and three months ended June 30, 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.
