| Subsequent Event                 | Subsequent EventOn April 1 2015, we closed on the issuance of $450.0 million of new 6.875% Senior Notes due 2025 at an issue price of 99.105% issued by our wholly owned subsidiary, GCI, Inc. ("2025 Notes").  The net proceeds of the offering will be used to retire our existing 2019 Notes (see Note 6(b) of our December 31, 2014 annual report on Form 10-K).  We paid closing costs totaling $7.7 million in connection with the offering, which will be recorded as deferred loan costs and will be amortized over the term of the 2025 Notes.  We expect to record a $27.7 million loss on extinguishment of debt on our Consolidated Statements of Operations in the second quarter of 2015. |
