Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. ORGANIZATION Basis of Preparation of Unaudited Consolidated Financial Statements Mediacom Broadband LLC (“Mediacom Broadband,” and collectively with its subsidiaries, “we,” “our” or “us”) is a Delaware limited liability company wholly-owned by Mediacom Communications Corporation (“MCC”). MCC is involved in the acquisition and operation of cable systems serving smaller cities and towns in the United States, and its cable systems are owned and operated through our operating subsidiaries and those of Mediacom LLC, a New York limited liability company wholly-owned by MCC. As limited liability companies, we and Mediacom LLC are not subject to income taxes and, as such, are included in the consolidated federal and state income tax returns of MCC, a C corporation. Our principal operating subsidiaries conduct all of our consolidated operations and own substantially all of our consolidated assets. Our operating subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to make funds available to us. We have prepared these unaudited consolidated financial statements in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of management, such statements include all adjustments, consisting of normal recurring accruals and adjustments, necessary for a fair statement of our consolidated results of operations, financial position, and cash flows for the interim periods presented. The accounting policies followed during such interim periods reported are in conformity with generally accepted accounting principles in the United States of America and are consistent with those applied during annual periods. For a summary of our accounting policies and other information, refer to our Annual Report on Form 10-K Mediacom Broadband Corporation (“Broadband Corporation”), a Delaware corporation wholly-owned by us, co-issued, jointly and severally with us, public debt securities. Broadband Corporation has no operations, revenues or cash flows and has no assets, liabilities or stockholders’ equity on its balance sheet, other than a one-hundred dollar receivable from an affiliate and the same dollar amount of common stock. Therefore, separate financial statements have not been presented for this entity. Franchise fees imposed by local governmental authorities are collected on a monthly basis from our customers and are periodically remitted to the local governmental authorities. Because franchise fees are our obligation, we present them on a gross basis within revenues with a corresponding operating expense. Franchise fees reported on a gross basis amounted to $5.8 million and $5.4 million for the three months ended September 30, 2016 and 2015, respectively, and $17.6 million and $17.2 million for the nine months ended September 30, 2016 and 2015, respectively. Reclassifications Certain reclassifications have been made to prior year amounts to conform to the current year presentation.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	2. RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09 - Revenue from Contracts with Customers Financial Reporting by Cable Television Companies Revenue from Contracts with Customers, In August 2014, the FASB issued new guidance that requires management to assess the Company’s ability to continue as a going concern and to provide related disclosures in certain circumstances. This guidance is effective for interim and fiscal years ending after December 15, 2016, with early adoption permitted. We do not expect this guidance will have a material impact on our financial position, operations or cash flows. In April 2015 (as amended in August 2015), the FASB issued ASU No. 2015-03 (and ASU 2015-15) - Interest—Imputation of Interest Simplifying the Presentation of Debt Issuance Costs In April 2015, the FASB issued ASU 2015-05 - Intangibles—Goodwill and Other—Internal-Use Software In February 2016, the FASB issued ASU 2016-02 - Leases In August 2016, the FASB issued ASU 2016-15 – Statement of Cash Flows Statement of Cash Flows

Fair Value Disclosures [Abstract]
Fair Value	3. FAIR VALUE The tables below set forth our financial assets and liabilities measured at fair value on a recurring basis using a market-based approach. Our financial assets and liabilities, all of which represent interest rate exchange agreements (which we refer to as “interest rate swaps”) have been categorized according to the three-level fair value hierarchy established by Accounting Standards Codification (“ASC”) No. 820 — Fair Value Measurement • Level 1 — Quoted market prices in active markets for identical assets or liabilities. • Level 2 — Observable market based inputs or unobservable inputs that are corroborated by market data. • Level 3 — Unobservable inputs that are not corroborated by market data. Fair Value as of September 30, 2016 Level 1 Level 2 Level 3 Total Assets Interest rate exchange agreements $ — $ — $ — $ — Liabilities Interest rate exchange agreements $ — $ 6,190 $ — $ 6,190 Fair Value as of December 31, 2015 Level 1 Level 2 Level 3 Total Assets Interest rate exchange agreements $ — $ 1,818 $ — $ 1,818 Liabilities Interest rate exchange agreements $ — $ 3,695 $ — $ 3,695 The fair value of our interest rate swaps represents the estimated amount that we would receive or pay to terminate such agreements, taking into account projected interest rates, based on quoted London Interbank Offered Rate (“LIBOR”) futures and the remaining time to maturity. While our interest rate swaps are subject to contractual terms that provide for the net settlement of transactions with counterparties, we do not offset assets and liabilities under these agreements for financial statement presentation purposes, and assets and liabilities are reported on a gross basis. As of September 30, 2016, we recorded a current liability in accounts payable, accrued expenses and other current liabilities of $3.2 million, a long-term liability in other non-current liabilities of $3.0 million and no current or long-term assets. As of December 31, 2015, we recorded a long-term asset of $1.8 million, a current liability in accounts payable, accrued expenses and other current liabilities of $3.7 million, and no current assets or long-term liabilities. As a result of the changes in the mark-to-market valuations on our interest rate swaps, we recorded a net gain on derivatives of $4.4 million and a net loss of $4.9 million for the three months ended September 30, 2016 and 2015, respectively, and a net loss on derivatives of $4.3 million and a net gain on derivatives of $1.2 million for the nine months ended September 30, 2016 and 2015, respectively.

On the same date, MCC received the $75.0 million of capital contributions from Mediacom LLC. We recorded a loss on early extinguishment of debt of $1.2 million for the nine months ended September 30, 2016, which represented the write-off of certain unamortized financing costs as a result of the repayment of Term Loan I. Bank Credit Facility As of September 30, 2016, we maintained a $1.388 billion bank credit facility (the “credit facility”), comprising: • $368.5 million of revolving credit commitments, which expire on October 10, 2019; • $145.8 million of outstanding borrowings under Term Loan A, which mature on January 15, 2021; • $580.5 million of outstanding borrowings under Term Loan H, which mature on January 29, 2021; • $293.3 million of outstanding borrowings under Term Loan J, which mature on June 30, 2021. As of September 30, 2016, we had $223.4 million of unused revolving credit commitments, all of which were available to be borrowed and used for general corporate purposes, after giving effect to approximately $135.4 million of outstanding loans and $9.7 million of letters of credit issued thereunder to various parties as collateral. The credit facility is collateralized by our ownership interests in our operating subsidiaries and is guaranteed by us on a limited recourse basis to the extent of such ownership interests. All outstanding debt under the credit facility may be prepaid, at our option, at par any time prior to maturity. As of September 30, 2016, the credit agreement governing the credit facility (the “credit agreement”) required our operating subsidiaries to maintain a total leverage ratio (as defined in the credit agreement) of no more than 5.0 to 1.0 and an interest coverage ratio (as defined in the credit agreement) of no less than 2.0 to 1.0. For all periods through September 30, 2016, our operating subsidiaries were in compliance with all covenants under the credit agreement. Interest Rate Swaps We have entered into several interest rate exchange agreements (which we refer to as “interest rate swaps”) with various banks to fix the variable rate on a portion of our borrowings under the credit facility to reduce the potential volatility in our interest expense that may result from changes in market interest rates. Our interest rate swaps have not been designated as hedges for accounting purposes, and have been accounted for on a mark-to-market basis as of, and for the three and nine months ended, September 30, 2016 and 2015, respectively. As of September 30, 2016, we had interest rate swaps that fixed the variable portion of $600 million of borrowings at a rate of 1.5%, all of which are scheduled to expire during December 2018. As of September 30, 2016, the weighted average interest rate on outstanding borrowings under the credit facility, including the effect of our interest rate swaps, was 3.6%. Senior Notes As of September 30, 2016, we had $500 million of outstanding senior notes, comprising $200 million of 5 1 2 3 8 Deferred Financing Costs We adopted ASU 2015-03 and ASU 2015-15 as of January 1, 2016 and implemented retrospectively as of December 31, 2015. We reclassified $15.4 million of deferred financing costs from other assets, net to long-term debt, net (less current portion) as of September 30, 2016 in accordance with such guidance. We reclassified $20.2 million of deferred financing costs from other assets, net to long-term debt, net (less current portion) as of December 31, 2015 in accordance with such guidance. See Note 2. Debt Ratings MCC’s corporate credit ratings are Ba3 by Moody’s and BB by Standard and Poor’s (“S&P”), and our senior unsecured ratings are B2 by Moody’s and B+ by S&P, all with a stable outlook. There are no covenants, events of default, borrowing conditions or other terms in the credit agreement or indentures that are based on changes in our credit rating assigned by any rating agency. Fair Value The fair values of our senior notes and outstanding debt under the credit facility (which were calculated based upon unobservable inputs that are corroborated by market data that we determine to be Level 2), were as follows (dollars in thousands): September 30, December 31, 5 1 2 $ 208,000 $ 191,500 6 3 8 318,000 291,750 Total senior notes $ 526,000 $ 483,250 Bank credit facility $ 1,160,820 $ 1,317,990

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	11. GOODWILL AND OTHER INTANGIBLE ASSETS In accordance with the FASB’s ASC No. 350 — Intangibles — Goodwill and Other We last evaluated the factors surrounding our Mediacom Broadband reporting unit as of October 1, 2015 and did not believe that it was “more likely than not” that a goodwill impairment existed at that time. As such, we did not perform Step 2 of the goodwill impairment test. We last evaluated our other intangible assets as of October 1, 2015 and did not believe that it was “more likely than not” that an impairment existed at that time. Because we believe there has not been a meaningful change in the long-term fundamentals of our business during the first nine months of 2016, we determined that there has been no triggering event under ASC 350 and, as such, no interim impairment test was required for our goodwill and other intangible assets as of September 30, 2016.
