	(Unaudited)
	Note 1: Condensed Consolidated Financial Statements
	Basis of Presentation
	We have prepared these unaudited condensed consolidated financial statements based on Securities and Exchange Commission (“SEC”) rules that permit reduced disclosure for interim periods. These financial statements include all adjustments that are necessary for a fair presentation of our consolidated results of operations, financial condition and cash flows for the periods shown, including normal, recurring accruals and other items. The consolidated results of operations for the interim periods presented are not necessarily indicative of results for the full year.
	The year-end condensed consolidated balance sheet was derived from audited financial statements but does not include all disclosures required by generally accepted accounting principles in the United States (“GAAP”). For a more complete discussion of our accounting policies and certain other information, refer to our consolidated financial statements included in our 2012 Annual Report on Form 10-K.
	Reclassifications have been made to our condensed consolidated financial statements for the prior year periods to conform to classifications used in the current year periods.

Significant Transactions [Abstract]
Significant Transactions	Note 2: Significant Transactions
	Redemption Transaction
	On March 19, 2013, Comcast acquired GE's remaining 49% common equity interest in NBCUniversal Holdings for approximately $16.7 billion (the “Redemption Transaction”). In addition to this transaction, we purchased from GE certain properties we occupy at 30 Rockefeller Plaza in New York City and CNBC's headquarters in Englewood Cliffs, New Jersey for approximately $1.4 billion.
	The total consideration for these transactions consisted of $11.4 billion of cash on hand (of which we funded $4.6 billion); $4 billion of senior debt securities issued by NBCUniversal Enterprise, Inc. (“NBCUniversal Enterprise”), a holding company whose principal assets are its interests in NBCUniversal Holdings; $750 million of cash funded through Comcast's commercial paper program; $1.25 billion of borrowings under NBCUniversal Enterprise's credit facility, which replaced our credit facility; and $725 million aggregate liquidation preference of Series A cumulative preferred stock of NBCUniversal Enterprise. After the close of the transaction, GE sold the interests in NBCUniversal Enterprise's senior debt securities and preferred stock it acquired in the Redemption Transaction to unaffiliated third parties.
	Following the close of the Redemption Transaction, Comcast owns 96% of NBCUniversal Holdings' common units and NBCUniversal Enterprise owns the remaining 4%. NBCUniversal Enterprise is now a consolidated subsidiary of Comcast, but we do not have any ownership interests in NBCUniversal Enterprise. NBCUniversal Enterprise also owns all of NBCUniversal Holdings' preferred units with a $9.4 billion aggregate liquidation preference. NBCUniversal Holdings is required to make quarterly payments to NBCUniversal Enterprise at an initial rate of 8.25% per annum on the $9.4 billion aggregate liquidation preference of the preferred units. On March 1, 2018, and thereafter on every fifth anniversary of such date, this rate will reset to 7.44% plus the yield on actively traded United States Treasury securities having a 5 year maturity. NBCUniversal Holdings has the right to redeem all of the preferred units during the 30 day period beginning on March 1, 2018, and NBCUniversal Enterprise has the right to cause NBCUniversal Holdings to redeem 15% of its preferred units during the 30 day period beginning on March 19, 2020. The price and units in a redemption initiated by either party will be based on the liquidation preference plus accrued but unpaid dividends and adjusted, in the case of an exercise of NBCUniversal Enterprise's right, to the extent the equity value of NBCUniversal Holdings is less than the liquidation preference. Our cash flows are, and will continue to be, the primary source of funding for the required payments and any future redemption of the NBCUniversal Holdings preferred units.

Related Party Transactions [Abstract]
Related Party Transactions	Note 3: Related Party Transactions
	In the ordinary course of our business, we enter into transactions with Comcast. Following the close of the Redemption Transaction and the subsequent sale of NBCUniversal Enterprise's preferred stock and senior notes by GE to unaffiliated third parties, we no longer consider GE to be a related party.
	We generate revenue from Comcast primarily from the distribution of our cable network programming and, to a lesser extent, the sale of advertising and our owned programming, and we incur expenses primarily related to various support services provided by Comcast to us.
	On March 19, 2013, as part of the Comcast cash management process, we and Comcast entered into a revolving credit agreement under which we can borrow up to $3 billion from Comcast and Comcast can borrow up to $3 billion from us. Amounts owed by Comcast to us under the revolving credit agreement, including accrued interest, are presented under the caption “note receivable from Comcast” in our condensed consolidated balance sheet. The revolving credit agreements bear interest at floating rates equal to the interest rate under the Comcast and Comcast Cable Communications, LLC revolving credit facility (the “Comcast revolving credit facility”). The interest rate on the Comcast revolving credit facility consists of a base rate plus a borrowing margin that is determined based on Comcast's credit rating. As of September 30, 2013, the interest rate was 1.252%.
	The following tables present transactions with Comcast and its consolidated subsidiaries that are included in our condensed consolidated financial statements. Other than the transactions discussed in Note 2 and the Station Venture transaction discussed in Note 5, the amounts related to transactions with GE and its consolidated subsidiaries that occurred prior to the close of the Redemption Transaction were not material.

	Distributions to NBCUniversal Holdings
	In addition to the transactions above, we make distributions to NBCUniversal Holdings on a periodic basis to enable its owners to meet their obligations to pay taxes on taxable income generated by our businesses. We also make quarterly distributions to NBCUniversal Holdings to enable it to make its required quarterly payments to NBCUniversal Enterprise at an initial annual rate of 8.25% on the $9.4 billion aggregate liquidation preference of preferred units. These distributions are presented under the caption “distributions to member” in our condensed consolidated statement of cash flows. Following the close of the Redemption Transaction, none of these distributions to NBCUniversal Holdings are attributable to GE.
	In connection with the Redemption Transaction, we also made a distribution of $3.2 billion to NBCUniversal Holdings to fund a portion of the Redemption Transaction. This distribution is presented separately in our condensed consolidated statement of cash flows.

	Equity Method
	In June 2013, we received a distribution from The Weather Channel Holding Corp. (“The Weather Channel”) of $152 million, of which $128 million was recorded as a return of our investment in The Weather Channel and is included under the caption “return of capital from investees” in our condensed consolidated statement of cash flows.
	In July 2013, we entered into an agreement to provide capital contributions totaling $247 million to Hulu, LLC (“Hulu”), which we had previously accounted for as a cost method investment. As of September 30, 2013, we had contributed $123 million under this agreement and the remaining amounts will be provided at a future date as specified under the terms of the agreement. As a result of our agreement to provide funding to Hulu, which was our first capital contribution since Comcast acquired its interest in Hulu as part of its acquisition of a controlling interest in NBCUniversal Holdings (the “Joint Venture transaction”), we began to apply the equity method of accounting for our investment in Hulu. The change to the equity method of accounting requires that we retroactively record our portion of Hulu's accumulated losses since the date of the Joint Venture transaction. Prior period financial statements have not been restated as the amounts are not material in the current period or any of the prior periods affected. Accordingly, equity in net income (losses) of investees, net for the three and nine months ended September 30, 2013, included $135 million of equity losses, which represents our portion of Hulu's accumulated losses from the date of the Joint Venture transaction.
	Variable Interest Entities
	Station Venture
	We previously held an equity interest in Station Venture Holdings, LLC (“Station Venture”), a nonconsolidated variable interest entity, and the remaining equity interests in Station Venture were held by LIN TV, Corp. Station Venture was the obligor on an $816 million senior secured note (the “Station Venture note”) that was due in 2023 to General Electric Capital Corporation (“GECC”) as servicer. The Station Venture note, among other things, was collateralized by substantially all of the assets of Station Venture and Station Venture Operations, LP (“Station LP”). Station LP was a less than wholly owned consolidated subsidiary of ours. In connection with the Joint Venture transaction, a liability of $482 million was recorded to noncurrent liabilities in Comcast's allocation of purchase price, which represented the fair value of the net assets of Station LP. In February 2013, Comcast closed an agreement with GE, GECC and LIN TV under which, among other things, we purchased the Station Venture note from GECC for $602 million, which represented the agreed upon fair value of the assets of Station LP. As of the closing date of the transaction, the $482 million recorded liability was effectively settled, and Station Venture and Station LP became wholly owned subsidiaries. We now consolidate Station Venture, and the Station Venture note is eliminated in consolidation. Due to the related party nature of this transaction, the excess of the purchase price of the Station Venture note over the recorded amount of the liability was recorded to member's capital.

Long-term Debt
Long-Term Debt	Note 7: Long-Term Debt
	Senior Notes and Other Debt
	As of September 30, 2013, our debt had an estimated fair value of $11.9 billion. The estimated fair value of our publicly traded debt is based on quoted market values for the debt. To estimate the fair value of debt for which there are no quoted market prices, we use interest rates available to us for debt with similar terms and remaining maturities.
	Revolving Credit Facility
	In connection with the Redemption Transaction, on March 19, 2013, NBCUniversal Enterprise amended and restated our existing credit agreement to, among other things, substitute NBCUniversal Enterprise for us as the sole borrower to the revolving credit facility. As a result, we no longer have a revolving credit facility with third-party banks. Following the amendments to our credit agreement, our commercial paper program was terminated and we entered into a revolving credit agreement with Comcast. See Note 3 for additional information on the revolving credit agreement with Comcast.
	Cross-Guarantee Structure
	On March 27, 2013, we, Comcast and four of Comcast's wholly owned cable holding company subsidiaries (the “cable guarantors”) entered into a series of agreements and supplemental indentures to include us as a part of Comcast's existing cross-guarantee structure. As members of the cross-guarantee structure, Comcast and the cable guarantors fully and unconditionally guarantee our public debt securities, and we fully and unconditionally guarantee all of Comcast's and the cable guarantors' public debt securities. As of September 30, 2013, we guaranteed $30 billion of outstanding debt securities of Comcast and the cable guarantors. We also fully and unconditionally guarantee the $6.25 billion Comcast revolving credit facility due 2017 of which no amounts were outstanding as of September 30, 2013.
	We do not, however, guarantee the obligations of NBCUniversal Enterprise with respect to its $4 billion aggregate principal amount of senior notes, $1.35 billion credit facility or $725 million liquidation preference of Series A cumulative preferred stock.

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 8: Fair Value Measurements
	The accounting guidance related to financial assets and financial liabilities (“financial instruments”) establishes a hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques (market approach, income approach and cost approach). Level 1 consists of financial instruments whose values are based on quoted market prices for identical financial instruments in an active market. Level 2 consists of financial instruments that are valued using models or other valuation methodologies. These models use inputs that are observable either directly or indirectly. Level 3 consists of financial instruments whose values are determined using pricing models that use significant inputs that are primarily unobservable, discounted cash flow methodologies or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Our financial instruments that are accounted for at fair value on a recurring basis are presented in the table below.
	Recurring Fair Value Measures

	Total		$	-	$	21	$	1,130	$	1,151	$	1,069
	Contractual Obligations
	The fair values of the contractual obligations in the table above are primarily based on certain expected future discounted cash flows, the determination of which involves the use of significant unobservable inputs. The most significant unobservable inputs we use are our estimates of the future revenue we expect to generate from certain of our entities. The discount rates used in the measurements of fair value were between 11% and 14% and are based on the underlying risk associated with our estimate of future revenue, as well as the terms of the respective contracts. The fair value adjustments to these contractual obligations are sensitive to the assumptions related to future revenue, as well as to current interest rates, and therefore, the adjustments are recorded to other income (expense), net in our condensed consolidated statement of income.
	In October 2013, in connection with a transaction between Comcast and Liberty Media Corporation (“Liberty Media”), Comcast acquired Liberty Media's interests in one of our contractual obligations and the liability associated with this contractual obligation is now considered a related party transaction with Comcast. The fair value of this contractual obligation as of September 30, 2013 was $383 million.

	Balance, September 30, 2013	$	1,130
	Nonrecurring Fair Value Measures
	We have assets and liabilities that we are required to record at fair value on a nonrecurring basis when certain circumstances occur. In the case of film or stage play production costs, upon the occurrence of an event or change in circumstance that may indicate that the fair value of a production is less than its unamortized costs, we determine the fair value of the production and record an adjustment for the amount by which the unamortized capitalized costs exceed the production's fair value. The estimate of the fair value of a production is determined using Level 3 inputs, primarily an analysis of future expected cash flows. Adjustments to capitalized film production costs of $150 million and $155 million were recorded during the nine months ended September 30, 2013 and 2012, respectively.

Receivables Monetization [Abstract]
Receivables Monetization	Note 11: Receivables Monetization
	We monetize certain of our accounts receivable under programs with a syndicate of banks. We transfer, at fair value, a significant portion of our accounts receivable that are to be monetized to NBCUniversal Receivables Funding LLC (“Funding LLC”), a wholly owned subsidiary of ours. The operating activities of Funding LLC are restricted to the transfer and sale of the monetized receivables to a third-party syndicate of banks. Due to these restrictions, Funding LLC is considered a variable interest entity, which we consolidate because we are the primary beneficiary. The assets and liabilities of this entity primarily represent the receivables and cash receipts that are not yet remitted to the programs as of the balance sheet date.
	We account for receivables monetized through these programs as sales in accordance with the appropriate accounting guidance. We receive deferred consideration from the assets sold in the form of a receivable, which is funded by residual cash flows after the senior interests have been fully paid. The deferred consideration is included in receivables, net at its initial fair value, which reflects the net cash flows we expect to receive related to these interests. The accounts receivable we sold that underlie the deferred consideration are generally short-term in nature and, therefore, the fair value of the deferred consideration approximated its carrying value as of September 30, 2013 and December 31, 2012.
	We are responsible for servicing the receivables and remitting collections to the purchasers under the monetization programs. We perform this service for a fee that is equal to the prevailing market rate for such services. As a result, no servicing asset or liability has been recorded on our condensed consolidated balance sheet as of September 30, 2013 and December 31, 2012. The servicing fees are recorded as a component of other income (expense), net.
	The net cash payments on transfers that are included within net cash provided by operating activities in our condensed consolidated statement of cash flows were $367 million for the nine months ended September 30, 2013. The net cash proceeds on transfers that are included within net cash provided by operating activities in our condensed consolidated statement of cash flows were $70 million for the nine months ended September 30, 2012. The receivables monetization program did not have a material effect on our condensed consolidated statement of income for the periods presented.

	In addition to the amounts presented above, we had $616 million and $882 million payable to our monetization programs as of September 30, 2013 and December 31, 2012, respectively. These amounts represent cash receipts that were not yet remitted to the monetization programs as of the balance sheet date and are recorded to accounts payable and accrued expenses related to trade creditors.

Financial Data By Business Segment [Abstract]
Financial Data by Business Segment	Note 12: Financial Data by Business Segment
	We present our operations in four reportable business segments:
	Cable Networks: Consists primarily of our national cable networks, our regional sports and news networks, our international cable networks, our cable television production operations, and our related digital media properties.
	Broadcast Television: Consists primarily of the NBC and Telemundo broadcast networks, our NBC and Telemundo owned local broadcast television stations, our broadcast television production operations, and our related digital media properties.
	Filmed Entertainment: Consists primarily of the operations of Universal Pictures, which produces, acquires, markets and distributes filmed entertainment worldwide.
	Theme Parks: Consists primarily of our Universal theme parks in Orlando and Hollywood.
	In evaluating the profitability of our operating segments, the components of net income (loss) below operating income (loss) before depreciation and amortization are not separately evaluated by our management. Our financial data by business segment is presented in the tables below.

	Included in Eliminations are transactions that our segments enter into with one another, which consisted primarily of the licensing of film and television content from our Filmed Entertainment and Broadcast Television segments to our Cable Networks segment.
	No single customer accounted for a significant amount of revenue in any period.
	We use operating income (loss) before depreciation and amortization, excluding impairment charges related to fixed and intangible assets and gains or losses from the sale of assets, if any, as the measure of profit or loss for our operating segments. This measure eliminates the significant level of noncash amortization expense that results from intangible assets recognized in business combinations. Additionally, it is unaffected by our capital structure or investment activities. We use this measure to evaluate our consolidated operating performance and the operating performance of our operating segments and to allocate resources and capital to our operating segments. It is also a significant performance measure in our annual incentive compensation programs. We believe that this measure is useful to investors because it is one of the bases for comparing our operating performance with that of other companies in our industries, although our measure may not be directly comparable to similar measures used by other companies. This measure should not be considered a substitute for operating income (loss), net income (loss) attributable to NBCUniversal, net cash provided by operating activities, or other measures of performance or liquidity we have reported in accordance with GAAP.
