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 (“ASC 350”), the amortization of goodwill and indefinite-lived intangible assets is prohibited and requires such assets to be tested annually for impairment, or more frequently if impairment indicators arise. We have determined that our goodwill and franchise rights are indefinite-lived assets and therefore not amortizable. 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.

The entire disclosure for the aggregate amount of goodwill and a description of intangible assets, which may include (a) for amortizable intangible assets (also referred to as finite-lived intangible assets), the carrying amount, the amount of any significant residual value, and the weighted-average amortization period, (b) for intangible assets not subject to amortization (also referred to as indefinite-lived intangible assets), the carrying amount, and (c) the amount of research and development assets acquired and written off in the period, including the line item in the income statement in which the amounts written off are aggregated, if not readily apparent from the income statement. Also discloses (a) for amortizable intangibles assets in total and by major class, the gross carrying amount and accumulated amortization, the total amortization expense for the period, and the estimated aggregate amortization expense for each of the five succeeding fiscal years, (b) for intangible assets not subject to amortization the carrying amount in total and by major class, and (c) for goodwill, in total and for each reportable segment, the changes in the carrying amount of goodwill during the period (including the aggregate amount of goodwill acquired, the aggregate amount of impairment losses recognized, and the amount of goodwill included in the gain (loss) on disposal of a reporting unit). If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final. May also disclose the nature and amount of any significant adjustments made to a previous estimate of an impairment loss.
