Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation
	Organization
	Charter Communications, Inc. (“Charter”) is a holding company whose principal asset is a 100% common equity interest in Charter Communications Holding Company, LLC (“Charter Holdco”). Charter owns cable systems through its subsidiaries, which are collectively, with Charter, referred to herein as the “Company.” All significant intercompany accounts and transactions among consolidated entities have been eliminated.
	The Company is a cable operator providing services in the United States. The Company offers to residential and commercial customers traditional cable video programming, Internet services, and voice services, as well as advanced video services such as video on demand, high definition television, and digital video recorder (“DVR”) service. The Company sells its cable video programming, Internet, voice, and advanced video services primarily on a subscription basis. The Company also sells local advertising on cable networks and on the Internet and provides fiber connectivity to cellular towers.
	Basis of Presentation
	The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, certain information and footnote disclosures typically included in Charter's Annual Report on Form 10-K have been condensed or omitted for this quarterly report. The accompanying condensed consolidated financial statements are unaudited and are subject to review by regulatory authorities. However, in the opinion of management, such financial statements include all adjustments, which consist of only normal recurring adjustments, necessary for a fair presentation of the results for the periods presented. Interim results are not necessarily indicative of results for a full year.
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Areas involving significant judgments and estimates include capitalization of labor and overhead costs; depreciation and amortization costs; impairments of and acquisition accounting for property, plant and equipment, intangibles and goodwill; income taxes; contingencies and programming expense. Actual results could differ from those estimates.
	Certain prior period amounts, primarily merger and acquisition costs, have been reclassified to conform with the 2015 presentation.

Business Combination Disclosure	Acquisitions and Dispositions
	Comcast Transactions
	On April 25, 2014, the Company entered into a binding definitive agreement (the “Comcast Transactions Agreement”) with Comcast Corporation (“Comcast”), which contemplated the following transactions: (1) an asset purchase, (2) an asset exchange and (3) a contribution and spin-off transaction (collectively, the “Comcast Transactions”). Pursuant to the terms of the Comcast Transactions Agreement, Comcast had the right to terminate the Comcast Transactions Agreement upon termination of the merger agreement among Comcast, Time Warner Cable Inc. (“TWC”) and Tango Acquisition Sub, Inc. (the “Merger Agreement”). On April 24, 2015, Comcast and TWC terminated the Merger Agreement, and Comcast delivered a notice of termination of the Comcast Transactions Agreement to Charter (the “Termination Notice”).
	Charter Communications Operating, LLC ("Charter Operating") received a commitment from certain financial institutions to provide incremental senior secured term loan facilities totaling up to $8.4 billion and a senior secured incremental revolving facility equal to $500 million under the Charter Operating credit facility. The amount of the commitment for the incremental term loan facilities was reduced by $3.5 billion at the closing of the CCOH Safari, LLC notes offering discussed below. Further, under the commitment, in September 2014, Charter Operating executed a Term G Loan Incremental Activation Notice (the “Notice”) under its existing Amended and Restated Credit Agreement, dated as of April 11, 2012, as further amended, restated, supplemented or otherwise modified from time to time (the “Credit Agreement”). The Notice established a new tranche of Term G Loan commitments (the “Term G Loans”) in an aggregate principal amount of $3.5 billion that was fully drawn on September 12, 2014. Charter intended to use the proceeds of the Term G Loans to fund the closing of the transactions contemplated by the Comcast Transactions Agreement and placed the proceeds into escrow pending such closing pursuant to an Escrow Credit Agreement among CCO Safari, LLC (“CCO Safari”), an indirect subsidiary of Charter, as borrower, Bank of America, N.A., as administrative agent (the "Escrow Agent”), and the lenders party thereto (the “Escrow Credit Agreement”) and an Escrow Agreement, dated as of September 12, 2014 (the “Escrow Agreement”), between CCO Safari and the Escrow Agent. As part of the establishment of the Escrow Credit Agreement and Escrow Agreement, Charter Operating assigned all of its obligations with respect to the Term G Loans and transferred all of the proceeds from the Term G Loans to CCO Safari who then assumed all obligations of Charter Operating under the Term G Loans.
	Pursuant to the provisions of the Escrow Agreement, Charter notified the Escrow Agent on April 27, 2015 that as a result of the termination of the Comcast Transactions Agreement, the escrow release conditions could not be satisfied and directed the Escrow Agent to release the escrowed funds and repay the Term G Loans. Under the Escrow Credit Agreement, the repayment price was equal to 99.5% of the principal amount outstanding under the loans, plus accrued and unpaid interest from the last interest payment date for the loans, but not including, the date of repayment. In addition, effective on termination of the Comcast Transactions Agreement, the remaining committed facilities of $1.4 billion of senior secured incremental term loans and the Company's option to activate $500 million of a senior secured incremental revolver were automatically terminated.
	In November 2014, CCOH Safari, LLC (“CCOH Safari”), an indirect subsidiary of Charter, issued $1.5 billion aggregate principal amount of 5.50% senior notes due 2022 and $2.0 billion aggregate principal amount of 5.75% senior notes due 2024 (collectively, the "CCOH Safari Notes"). Charter intended to use the proceeds to fund the closing of the transactions contemplated by the Comcast Transactions Agreement and placed the proceeds into escrow pending such closing pursuant to an Escrow Agreement, dated as of November 5, 2014 (the “CCOH Safari Escrow Agreement”), by and among U.S. Bank National Association (the “CCOH Safari Escrow Agent”), The Bank of New York Mellon Trust Company, N. A. (the “CCOH Safari Trustee”), and CCOH Safari.
	Under the CCOH Safari Escrow Agreement, upon Charter’s notification to the CCOH Safari Escrow Agent and the CCOH Safari Trustee that the Comcast Transactions Agreement had been terminated, the CCOH Safari Notes were subject to a special redemption. The special redemption price is equal to 100% of the initial issue price of the CCOH Safari Notes, plus accrued and unpaid interest from the issue date of the CCOH Safari Notes, up to, but not including, the date of such special redemption. On April 24, 2015, CCOH Safari notified the CCOH Safari Escrow Agent and the CCOH Safari Trustee that the Comcast Transactions Agreement had been terminated, that the CCOH Safari Notes were subject to a special redemption and directed the CCOH Safari Escrow Agent to disburse the proceeds and redeem the CCOH Safari Notes pursuant to the terms of the CCOH Safari Escrow Agreement.
	Bright House Transaction
	As previously announced, on March 31, 2015, the Company entered into a definitive Contribution Agreement (the “Bright House Contribution Agreement”) with Advance/Newhouse Partnership (“A/N”), A/NPC Holdings LLC, CCH I, LLC ("New Charter"), an indirect subsidiary of the Company, and Charter Communications Holdings, LLC (“Charter Holdings”), the Company's wholly owned subsidiary, pursuant to which Charter would become the owner of the membership interests in Bright House Networks, LLC (“Bright House”) and any other assets (other than certain excluded assets) primarily related to Bright House (the “Bright House Transaction”). In connection with the Bright House Contribution Agreement, the Company also entered into an amended and restated Stockholders Agreement (the “Bright House Stockholders Agreement”) with Liberty Broadband Corporation (“Liberty”) and A/N, which Bright House Stockholders Agreement would replace the Company's existing stockholders agreement with Liberty, as amended October 14, 2014.
	The transaction contemplated by the Bright House Contribution Agreement is subject to completion of certain regulatory approvals, the approval of certain matters related to the Bright House Transaction by Charter’s stockholders, and other customary closing conditions. As announced by Charter on April 24, 2015, the Comcast Transactions Agreement was terminated by Comcast, and the closing of the Comcast Transactions had been a condition to the Bright House Contribution Agreement. As a result, the parties to the Bright House Stockholders’ Agreement are to consider and negotiate for a period of 30 days in good faith, amendments to the terms of the Bright House Transaction agreements that may be desirable to consummate the Bright House Transaction. No party is under any obligation to reach such an agreement and the Bright House Contribution Agreement and the Bright House Stockholders Agreement may be terminated by either party at any time within a 30 day period immediately following the expiration of the 30 day negotiation period.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Accounting for Derivative Instruments and Hedging Activities	Accounting for Derivative Instruments and Hedging Activities
	The Company uses interest rate derivative instruments to manage its interest costs and reduce the Company’s exposure to increases in floating interest rates. The Company manages its exposure to fluctuations in interest rates by maintaining a mix of fixed and variable rate debt. Using interest rate derivative instruments, the Company agrees to exchange, at specified intervals through 2017, the difference between fixed and variable interest amounts calculated by reference to agreed-upon notional principal amounts. The Company does not hold or issue derivative instruments for speculative trading purposes.
	The effect of interest rate derivatives on the Company’s condensed consolidated balance sheets is presented in the table below:
		March 31, 2015			December 31, 2014
	Accrued interest	$	—		$	2
	Other long-term liabilities	$	21		$	16
	Accumulated other comprehensive loss	$	(19	)	$	(22	)
	The Company holds interest rate derivative instruments not designated as hedges which are marked to fair value, with the impact recorded as a gain or loss on derivative instruments, net in the Company's condensed consolidated statements of operations. While these interest rate derivative instruments are not designated as cash flow hedges for accounting purposes, management continues to believe such instruments are closely correlated with the respective debt, thus managing associated risk. These interest rate derivative instruments were de-designated in 2013 and the balance that remains in accumulated other comprehensive loss for these interest rate derivative instruments is being amortized over the respective lives of the contracts and recorded as a loss within loss on derivative instruments, net in the Company's condensed consolidated statements of operations. The estimated net amount of existing losses that are reported in accumulated other comprehensive loss as of March 31, 2015 that is expected to be reclassified into earnings within the next twelve months is approximately $8 million.
	The effects of interest rate derivative instruments on the Company’s condensed consolidated statements of operations is presented in the table below.
		Three Months Ended March 31,
		2015			2014
	Loss on derivative instruments, net:
	Change in fair value of interest rate derivative instruments not designated as cash flow hedges	$	(3	)	$	4
	Loss reclassified from accumulated other comprehensive loss into earnings as a result of cash flow hedge discontinuance	(3		)	(6		)
		$	(6	)	$	(2	)
	As of March 31, 2015 and December 31, 2014, the Company had $1.1 billion and $1.4 billion, respectively, in notional amounts of interest rate derivative instruments outstanding. The notional amounts of interest rate instruments do not represent amounts exchanged by the parties and, thus, are not a measure of exposure to credit loss. The amounts exchanged were determined by reference to the notional amount and the other terms of the contracts.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	The accounting guidance establishes a three-level hierarchy for disclosure of fair value measurements, based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date, as follows:
	•	Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.
	•	Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
	•	Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value measurement.
	Financial Assets and Liabilities
	The Company has estimated the fair value of its financial instruments as of March 31, 2015 and December 31, 2014 using available market information or other appropriate valuation methodologies. Considerable judgment, however, is required in interpreting market data to develop the estimates of fair value. Accordingly, the estimates presented in the accompanying condensed consolidated financial statements are not necessarily indicative of the amounts the Company would realize in a current market exchange.
	The carrying amounts of cash and cash equivalents, receivables, payables and other current assets and liabilities approximate fair value because of the short maturity of those instruments.
	The Company's restricted cash and cash equivalents are primarily invested in money market funds and 90-day or less commercial paper. The money market funds are valued at the closing price reported by the fund sponsor from an actively traded exchange and commercial paper is valued at cost plus the accretion of the discount on a yield to maturity basis, which approximates fair value. The money market funds and commercial paper potentially subject us to concentrations of credit risk. The amount invested within any one financial instrument did not exceed $550 million during the three months ended March 31, 2015. As of March 31, 2015 and December 31, 2014, there were no significant concentrations of financial instruments in a single investee, industry or geographic location.
	The interest rate derivative instruments are valued using a present value calculation based on an implied forward LIBOR curve (adjusted for Charter Operating’s or counterparties’ credit risk). The weighted average pay rate for the Company’s currently effective interest rate derivative instruments was 1.61% and 1.87% at March 31, 2015 and December 31, 2014, respectively (exclusive of applicable spreads).
	The Company's financial instruments that are accounted for at fair value on a recurring basis are presented in the table below.

	Credit facilities		$	7,132	$	7,198	$	7,192	$	7,186
	The estimated fair value of the Company’s senior notes at March 31, 2015 and December 31, 2014 is based on quoted market prices in active markets and is classified within Level 1 of the valuation hierarchy, while the estimated fair value of the Company's credit facilities is based on quoted market prices in inactive markets and is classified within Level 2.
	Nonfinancial Assets and Liabilities
	The Company’s nonfinancial assets such as franchises, property, plant, and equipment, and other intangible assets are not measured at fair value on a recurring basis; however they are subject to fair value adjustments in certain circumstances, such as when there is evidence that an impairment may exist.  No impairments were recorded during the three months ended March 31, 2015 and 2014.

	All of Charter’s operations are held through Charter Holdco and its direct and indirect subsidiaries. Charter Holdco and the majority of its subsidiaries are generally limited liability companies that are not subject to income tax. However, certain of these limited liability companies are subject to state income tax. In addition, the indirect subsidiaries that are corporations are subject to federal and state income tax. All of the remaining taxable income, gains, losses, deductions and credits of Charter Holdco are passed through to Charter and its direct subsidiaries.
	For the three months ended March 31, 2015 and 2014, the Company recorded $35 million and $64 million of income tax expense, respectively. Income tax expense is recognized primarily through increases in deferred tax liabilities related to the Company's investment in Charter Holdco, as well as through current federal and state income tax expense and increases in the deferred tax liabilities of certain of our indirect corporate subsidiaries.
	As of March 31, 2015 and December 31, 2014, the Company had net deferred income tax liabilities of approximately $1.7 billion and $1.6 billion, respectively. Included in net deferred income tax liabilities is net current deferred tax assets of $23 million and $26 million as of March 31, 2015 and December 31, 2014, respectively, which are included in prepaid expenses and other current assets in the accompanying condensed consolidated balance sheets of the Company. Net deferred tax liabilities included approximately $236 million at March 31, 2015 and December 31, 2014, relating to certain indirect subsidiaries of Charter Holdco that file separate federal or state income tax returns.  The remainder of the Company's net deferred tax liability arose from Charter's investment in Charter Holdco, and was largely attributable to the characterization of franchises for financial reporting purposes as indefinite-lived.
	In determining the Company’s tax provision for financial reporting purposes, the Company establishes a reserve for uncertain tax positions unless such positions are determined to be “more likely than not” of being sustained upon examination, based on their technical merits. There is considerable judgment involved in making such a determination.  The Company did not have any unrecognized tax benefits as of March 31, 2015 or December 31, 2014.
	No tax years for Charter or Charter Holdco, for income tax purposes, are currently under examination by the IRS.  Tax years ending 2011 through 2014 remain subject to examination and assessment. Years prior to 2011 remain open solely for purposes of examination of Charter’s loss and credit carryforwards.

Contingencies	Contingencies
	The Company is a defendant or co-defendant in several lawsuits involving alleged infringement of various patents relating to various aspects of its businesses. Other industry participants are also defendants in certain of these cases. In the event that a court ultimately determines that the Company infringes on any intellectual property rights, the Company may be subject to substantial damages and/or an injunction that could require the Company or its vendors to modify certain products and services the Company offers to its subscribers, as well as negotiate royalty or license agreements with respect to the patents at issue. While the Company believes the lawsuits are without merit and intends to defend the actions vigorously, no assurance can be given that any adverse outcome would not be material to the Company's consolidated financial condition, results of operations, or liquidity. The Company cannot predict the outcome of any such claims nor can it reasonably estimate a range of possible loss.
	The Company is party to lawsuits and claims that arise in the ordinary course of conducting its business, including lawsuits claiming violation of wage and hour laws. The ultimate outcome of these other legal matters pending against the Company cannot be predicted, and although such lawsuits and claims are not expected individually to have a material adverse effect on the Company’s consolidated financial condition, results of operations or liquidity, such lawsuits could have, in the aggregate, a material adverse effect on the Company’s consolidated financial condition, results of operations or liquidity. Whether or not the Company ultimately prevails in any particular lawsuit or claim, litigation can be time consuming and costly and injure the Company's reputation.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards
	In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which is a comprehensive revenue recognition standard that will supersede nearly all existing revenue recognition guidance under U.S. GAAP.  The new standard provides a single principles-based, five-step model to be applied to all contracts with customers, which steps are to (1) identify the contract(s) with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when each performance obligation is satisfied. More specifically, revenue will be recognized when promised goods or services are transferred to the customer in an amount that reflects the consideration expected in exchange for those goods or services.  ASU 2014-09 will be effective, reflecting the one-year proposed deferral, for interim and annual periods beginning after December 15, 2017 (January 1, 2018 for the Company).  Early adoption of the standard is permitted but not before the original effective date. Companies can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The Company is currently in the process of evaluating the impact that the adoption of ASU 2014-09 will have on its consolidated financial statements and the selected method of transition to the new standard.
	In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"), which requires the cost of issuing debt to no longer be recorded as a separate asset but rather to be presented on the balance sheet as a direct reduction to the carrying value of the related debt liability, similar to the presentation of debt discounts.  ASU 2015-03 will be effective for interim and annual periods beginning after December 15, 2015 (January 1, 2016 for the Company) including retrospective conforming presentation of prior periods presented.  Early adoption of the standard is permitted. While the adoption of this standard may impact the presentation on the Company’s balance sheet, it will not affect the Company’s results of operations, financial condition or cash flows.
	In April 2015, the FASB issued ASU No. 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement ("ASU 2015-05"), which provides guidance in determining whether fees for purchasing cloud computing services (or hosted software solutions) are considered internal-use software or should be considered a service contract.  The cloud computing agreement that includes a software license should be accounted for in the same manner as internal-use software if customer has contractual right to take possession of the software during the hosting period without significant penalty and it is feasible to either run the software on customer’s hardware or contract with another vendor to host the software. Arrangements that don’t meet the requirements for internal-use software should be accounted for as a service contract. ASU 2015-05 will be effective for interim and annual periods beginning after December 15, 2015 (January 1, 2016 for the Company).  Early adoption of the standard is permitted.  The Company is currently in the process of evaluating the impact that the adoption of ASU 2015-05 will have on its consolidated financial statements.

	In April 2015, CCO Holdings and CCO Holdings Capital Corp. closed on transactions in which they issued $1.15 billion aggregate principal amount of 5.125% senior unsecured notes due 2023 (the "2023 Notes"), $750 million aggregate principal amount of 5.375% senior unsecured notes due 2025 (the "2025 Notes") and $800 million aggregate principal amount of 5.875% senior notes due 2027 (the "2027 Notes" and collectively, the “Notes”). The net proceeds from the issuance of the 2023 Notes and 2025 Notes were used to finance tender offers and will be used to finance a subsequent call in which $1.0 billion aggregate principal amount of CCO Holdings' outstanding 7.250% senior notes due 2017 and $700 million aggregate principal amount of CCO Holdings' outstanding 8.125% senior notes due 2020 have and will be repurchased, as well as for general corporate purposes.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Accounting for Derivative Instruments and Hedging Activities	The Company uses interest rate derivative instruments to manage its interest costs and reduce the Company’s exposure to increases in floating interest rates. The Company manages its exposure to fluctuations in interest rates by maintaining a mix of fixed and variable rate debt. Using interest rate derivative instruments, the Company agrees to exchange, at specified intervals through 2017, the difference between fixed and variable interest amounts calculated by reference to agreed-upon notional principal amounts. The Company does not hold or issue derivative instruments for speculative trading purposes.
