Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	(1) Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of GCI Liberty, Inc. and its controlled subsidiaries, as well as other equity securities and equity method investments (collectively, “GCI Liberty”, the “Company”, “us”, “we” and “our”). All significant intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements. GCI Liberty is made up of its wholly-owned subsidiary, GCI Holdings, LLC (“GCI Holdings”), a controlling interest in Evite, Inc. and non-controlling interests in Liberty Broadband Corporation ("Liberty Broadband"), Charter Communications, Inc. ("Charter"), and LendingTree, Inc. ("LendingTree"). These assets (other than GCI Holdings) were contributed by Liberty Interactive Corporation, now known as Qurate Retail, Inc. ("Qurate Retail"), in exchange for, among other things, a controlling interest in GCI Liberty, which was subsequently split-off (the "Holdco Split-Off"). The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results for the periods presented have been included. The results of operations for any interim period are not necessarily indicative of results for the full year. Additionally, certain prior period amounts have been reclassified for comparability with current period presentation. 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 at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. In December 2019, Chinese officials reported a novel coronavirus outbreak (“COVID-19”). COVID-19 has since spread through China and internationally. On March 11, 2020, the World Health Organization assessed COVID-19 as a global pandemic, causing many countries throughout the world to take aggressive actions, including imposing travel restrictions and stay-at-home orders, closing public attractions and restaurants, and mandating social distancing practices, which has caused a significant disruption to most sectors of the economy. COVID-19 has not had a material impact on GCI Liberty’s operating results for the three and six months ended June 30, 2020, however, management has increased certain estimates, including but not limited to, allowance for doubtful accounts. Other than these changes, we are not presently aware of any events or circumstances arising from the COVID-19 pandemic that would require us to update our estimates or judgments or revise the carrying value of our assets or liabilities. Our estimates may change, however, as new events occur and additional information is obtained, and any such changes will be recognized in the consolidated financial statements. Actual results could differ from estimates, and any such differences may be material to our financial statements. The Company, through its ownership of interests in subsidiaries and other companies, is primarily engaged in providing a full range of wireless, data, video, voice, and managed services to residential customers, businesses, governmental entities, and educational and medical institutions primarily in Alaska. The Company holds investments that are accounted for using the equity method. The Company does not control the decision making process or business management practices of these affiliates. Accordingly, the Company relies on management of these affiliates to provide it with accurate financial information prepared in accordance with GAAP that the Company uses in the application of the equity method. In addition, the Company relies on audit reports that are provided by the affiliates’ independent auditors on the financial statements of such affiliates. The Company is not aware, however, of any errors in or possible misstatements of the financial information provided by its equity affiliates that would have a material effect on its condensed consolidated financial statements. On August 6, 2020, GCI Liberty and Liberty Broadband entered into a definitive merger agreement under which Liberty Broadband agreed to acquire all of the outstanding shares of GCI Liberty in a stock-for-stock merger (the “Combination”). Under the terms of the merger agreement each holder of Series A and B common stock of GCI Liberty will receive 0.58 of a share of Series C common stock and Series B common Stock, respectively, of Liberty Broadband. Additionally, holders of a share of Series A Cumulative Redeemable Preferred Stock of GCI Liberty will receive one share of Series A Cumulative Redeemable Preferred Stock with mirror terms to be issued by Liberty Broadband. The Combination was recommended to the Company’s Board of Directors for approval by a special committee composed solely of independent, disinterested directors and advised by independent financial and legal advisors. The closing of the Combination is subject to certain customary conditions, including: (i) the adoption of the merger agreement by holders of a majority of the aggregate voting power of the GCI Liberty outstanding stock entitled to vote thereon not owned by John C. Malone and certain other persons, (ii) the adoption of the merger agreement by holders of a majority of the aggregate voting power of the Liberty Broadband outstanding stock entitled to vote thereon not owned by John C. Malone and certain other persons, (iii) the adoption of the merger agreement by holders of a majority of the aggregate voting power of the GCI Liberty outstanding stock entitled to vote thereon, (iv) approval of the Liberty Broadband stock issuance by holders of a majority of the aggregate voting power of the Liberty Broadband outstanding stock present in person or by proxy at the stockholder meeting and entitled to vote thereon and (v) the receipt of any applicable regulatory approvals. GCI Liberty and Liberty Broadband expect the Combination to close in the first half of 2021, subject to potential COVID-19 related delays. GCI Liberty has entered into certain agreements with Qurate Retail and Liberty Media Corporation ("Liberty Media") (or its subsidiary), all of which are separate, publicly traded companies, in order to govern certain relationships between the companies. None of these entities have any stock ownership, beneficial or otherwise, in the other. These agreements include an indemnification agreement, a reorganization agreement, a services agreement, a facilities sharing agreement and a tax sharing agreement. The reorganization agreement provides for, among other things, provisions governing the relationship between GCI Liberty and Qurate Retail (for accounting purposes a related party of GCI Liberty). The tax sharing agreement provides for the allocation and indemnification of tax liabilities and benefits between Qurate Retail and GCI Liberty and other agreements related to tax matters. Pursuant to the tax sharing agreement, GCI Liberty has agreed to indemnify Qurate Retail for taxes and tax-related losses resulting from the Holdco Split-Off to the extent such taxes or tax-related losses (i) result primarily from, individually or in the aggregate, the breach of certain restrictive covenants made by GCI Liberty (applicable to actions or failures to act by GCI Liberty and its subsidiaries following the completion of the Holdco Split-Off), or (ii) result from Section 355(e) of the Internal Revenue Code applying to the Holdco Split-Off as a result of the Holdco Split-Off being part of a plan (or series of related transactions) pursuant to which one or more persons acquire, directly or indirectly, a 50-percent or greater interest (measured by vote or value) in the stock of GCI Liberty (or any successor corporation). Pursuant to the services agreement, Liberty Media provides GCI Liberty with general and administrative services including legal, tax, accounting, treasury and investor relations support. See below for a description of an amendment to the services agreement entered into in December 2019. Under the facilities sharing agreement, GCI Liberty shares office space with Liberty Media and related amenities at its corporate headquarters. GCI Liberty reimburses Liberty Media for direct, out-of-pocket expenses incurred by Liberty Media in providing these services and for costs negotiated semi-annually. Liberty Media is a related party of GCI Liberty for accounting purposes as a result of the services agreement. Under these agreements, approximately $1.9 million and $2.2 million was reimbursable to Liberty Media for the three months ended June 30, 2020 and 2019, respectively, and $4.1 million and $4.5 million was reimbursable to Liberty Media for the six months ended June 30, 2020 and 2019, respectively. In addition, Qurate Retail and GCI Liberty have agreed to indemnify each other with respect to certain potential losses in respect of the HoldCo Split-Off. See note 3 for information related to the indemnification agreement. In December 2019, the Company entered into an amendment to the services agreement with Liberty Media in connection with Liberty Media’s entry into a new employment arrangement with Gregory B. Maffei, the Company’s President and Chief Executive Officer ("CEO"). Under the amended services agreement, components of his compensation will either be paid directly to him by each of the Company, Liberty TripAdvisor Holdings, Inc., Liberty Broadband, and Qurate Retail (collectively, the “Service Companies”) or reimbursed to Liberty Media, in each case, based on allocations among Liberty Media and the Service Companies set forth in the amended services agreement, currently set at 14% for the Company.

Earnings Attributable to GCI Li

Earnings Attributable to GCI Liberty Stockholders Per Common Share	6 Months Ended
	Jun. 30, 2020
Earnings Per Share [Abstract]
Earnings Attributable to GCI Liberty Stockholders Per Common Share	(2) Basic earnings (loss) per common share ("EPS") is computed by dividing net earnings (loss) by the weighted average number of common shares outstanding ("WASO") for the period. Diluted EPS presents the dilutive effect on a per share basis of potential common shares as if they had been converted at the beginning of the periods presented.

Fair Value Disclosures [Abstract]
Assets and Liabilities Measured at Fair Value	(3) Assets and Liabilities Measured at Fair Value For assets and liabilities required to be reported at fair value, GAAP provides a hierarchy that prioritizes inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs, other than quoted market prices included within Level 1, are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. The Company does not have any recurring assets or liabilities measured at fair value that would be considered Level 3. The Company’s assets and liabilities measured at fair value are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2020 December 31, 2019 ​ ​ ​ Quoted ​ ​ Quoted ​ ​ ​ ​ ​ ​ prices ​ ​ ​ ​ ​ prices ​ ​ ​ ​ ​ ​ ​ in active ​ Significant ​ ​ ​ in active ​ Significant ​ ​ ​ ​ ​ markets ​ other ​ ​ ​ markets ​ other ​ ​ ​ ​ ​ for identical ​ observable ​ ​ ​ for identical ​ observable ​ ​ ​ ​ ​ assets ​ inputs ​ ​ ​ assets ​ inputs Description ​ Total ​ (Level 1) ​ (Level 2) ​ Total ​ (Level 1) ​ (Level 2) ​ ​ amounts in thousands Cash equivalents ​ $ 478,509 ​ 478,509 ​ — ​ 533,484 ​ 533,484 ​ — Equity securities ​ $ 2,732,999 ​ 2,732,999 ​ — ​ 2,600,008 ​ 2,600,008 ​ — Investment in Liberty Broadband ​ $ 5,290,841 ​ 5,290,841 ​ — ​ 5,367,242 ​ 5,367,242 ​ — Derivative instrument liability ​ $ 61,437 ​ — ​ 61,437 ​ 71,305 ​ — ​ 71,305 Indemnification obligation ​ $ 214,671 ​ — ​ 214,671 ​ 202,086 ​ — ​ 202,086 Exchangeable senior debentures ​ $ 660,963 ​ — ​ 660,963 ​ 658,839 ​ — ​ 658,839 ​ On April 29, 2019, the Company terminated its previous variable forward and entered into a new 3-year variable forward with respect to 642,850 LendingTree shares. The variable forward was executed at the LendingTree closing price on April 29, 2019 of $376.35 per share and has a floor price of zero and has a cap price of $254.00 per share. The fair value of the variable forward was derived from a Black-Scholes-Merton model using observable market data as the significant inputs. The indemnification liability is due to Liberty Interactive LLC ("LI LLC") and pertains to the ability of holders of LI LLC’s 1.75% exchangeable debentures due 2016 (the "1.75% Exchangeable Debentures") to exercise their exchange right according to the terms of the 1.75% Exchangeable Debentures on or before October 5, 2023. Such amount will equal the difference between the exchange value and par value of the 1.75% Exchangeable Debentures at the time the exchange occurs. The indemnification obligation recorded in the accompanying condensed consolidated balance sheets as of June 30, 2020 represents the fair value of the estimated exchange feature included in the 1.75% Exchangeable Debentures primarily based on observable market data as significant inputs (Level 2). As of June 30, 2020, a holder of the 1.75% Exchangeable Debentures has the ability to exchange and, accordingly, such indemnification obligation is included as a current liability in the accompanying condensed consolidated balance sheets. Realized and Unrealized Gains (Losses) on Financial Instruments, net Realized and unrealized gains (losses) on financial instruments, net are comprised of changes in the fair value of the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ Six months ended ​ ​ June 30, ​ June 30, ​ ​ 2020 2019 ​ 2020 2019 ​ ​ ​ amounts in thousands ​ Equity securities ​ $ 395,075 ​ 258,718 ​ ​ 133,941 ​ 593,038 ​ Investment in Liberty Broadband ​ 565,107 ​ 532,669 ​ ​ (76,401) ​ 1,373,928 ​ Derivative instruments ​ (37,272) ​ (47,217) ​ ​ 9,868 ​ (118,361) ​ Indemnification obligation ​ (34,925) ​ (23,031) ​ ​ (12,585) ​ (54,826) ​ Exchangeable senior debentures ​ (27,118) ​ (42,041) ​ ​ (27,948) ​ (105,081) ​ ​ ​ $ 860,867 ​ 679,098 ​ ​ 26,875 ​ 1,688,698 ​ ​ The Company has elected to account for its exchangeable senior debentures using the fair value option. Changes in the fair value of the exchangeable senior debentures recognized in the condensed consolidated statements of operations are primarily due to market factors primarily driven by changes in the fair value of the underlying shares into which the debt is exchangeable. The Company isolates the portion of the unrealized gain (loss) attributable to the change in the instrument specific credit risk and recognizes such amount in other comprehensive income. The change in the fair value of the exchangeable senior debentures attributable to changes in the instrument specific credit risk was a loss of $26.5 million and a gain $2.6 million for the three months ended June 30, 2020 and 2019, respectively, and gains of $25.8 million and $6.6 million for the six months ended June 30, 2020 and 2019, respectively. The cumulative change was a gain of $20.2 million as of June 30, 2020.

Pursuant to Amendment No. 2, lenders have agreed to, among other things, extend the maturity date of the original term loan in an aggregate principal amount of $1.0 billion (the “Margin Loan”) to December 29, 2021 and provide commitments for a new delayed draw term loan facility in an aggregate principal amount of $300.0 million ("Delayed Draw Term Loan Facility"). This facility also provides a revolving credit facility in an aggregate principal amount of up to $200.0 million (the “Revolving Credit Facility”) and the original loan credit facility under the Margin Loan (the “Term Loan Facility”, and, together with the Revolving Credit Facility and the Delayed Draw Term Loan Facility, the "Margin Loan Facility" and the loans thereunder, the "Loans"). The Loans will mature on December 29, 2021 (the “Maturity Date”) and accrue interest at a rate equal to the 3-month LIBOR rate plus a per annum spread of 1.85%, subject to certain conditions and exceptions. Undrawn revolving commitments shall be available to Broadband Holdco from November 25, 2019 to but excluding the earlier of (i) the date that is one month prior to the Maturity Date and (ii) the date of the termination of such revolving commitments pursuant to the terms of the Margin Loan Agreement. The obligations under the Margin Loan Facility are secured by first priority liens on the shares of Liberty Broadband owned by Broadband Holdco and certain other cash collateral provided by Broadband Holdco. 42,681,842 shares of Liberty Broadband Series C common stock with a value of $5.3 billion were pledged by Broadband Holdco as collateral for the Loans as of June 30, 2020. On December 27, 2019, Broadband Holdco borrowed $100.0 million under the Revolving Credit Facility and $300.0 million under the Delayed Draw Term Loan Facility. As of June 30, 2020, $1,300.0 million in borrowings were outstanding under the Margin Loan Facility. Exchangeable Senior Debentures On June 18, 2018, GCI Liberty issued 1.75% exchangeable senior debentures due 2046 ("Exchangeable Senior Debentures"). Upon an exchange of debentures, GCI Liberty, at its option, may deliver Charter Class A common stock, cash or a combination of Charter Class A common stock and cash. Initially, 2.6989 shares of Charter Class A common stock are attributable to each $1,000 principal amount of debentures, representing an initial exchange price of approximately $370.52 for each share of Charter Class A common stock. A total of 1,288,051 shares of Charter Class A common stock are attributable to the debentures. Interest is payable quarterly on March 31, June 30, September 30 and December 31 of each year. The debentures may be redeemed by GCI Liberty, in whole or in part, on or after October 5, 2023. Holders of debentures also have the right to require GCI Liberty to purchase their debentures on October 5, 2023. The redemption and purchase price will generally equal 100% of the adjusted principal amount of the debentures plus accrued and unpaid interest. The Company has elected to account for the debentures using the fair value option. See note 3 for information related to unrealized gains (losses) on debt measured at fair value. As of June 30, 2020, the holders of the debentures will have the ability to exchange their debentures for the period from July 1, 2020 through at least September 30, 2020 given that the trading value of the reference shares exceeded 130% of the par value for twenty thirty Senior Notes On June 6, 2019, GCI, LLC, a wholly owned subsidiary of the Company, issued $325.0 million of 6.625% Senior Notes due 2024 at par ("2024 Notes"). The 2024 Notes are unsecured and the net proceeds were used to fund the redemption of $325.0 million aggregate outstanding principal amount of GCI, LLC’s 6.75% Senior Notes due 2021. Interest on the 2024 Notes and GCI, LLC’s 6.875% Senior Notes due 2025 (collectively, the “Senior Notes”), is payable semi-annually in arrears. The Senior Notes are redeemable at the Company’s option, in whole or in part, at a redemption price defined in the respective indentures, and accrued and unpaid interest (if any) to the date of redemption. The Senior Notes are stated net of an aggregate unamortized premium of $19.4 million at June 30, 2020. Such premium is being amortized to interest expense in the accompanying condensed consolidated statements of operations. Senior Credit Facility On December 27, 2018, GCI, LLC amended and restated the Fifth Amended and Restated Credit Agreement dated as of March 9, 2018 and refinanced the revolving credit facility and term loan A with a new revolving credit facility, leaving the existing Term Loan B in place (the "Senior Credit Facility"). The Senior Credit Facility provides a $240.7 million term loan B ("Term Loan B") and a $550.0 million revolving credit facility. GCI, LLC’s Senior Credit Facility Total Leverage Ratio (as defined in the Senior Credit Facility) may not exceed 6.50 to one and the Secured Leverage Ratio (as defined in the Senior Credit Facility) may not exceed 4.00 to one. The revolving credit facility borrowings that are LIBOR loans bear interest at a per annum rate equal to the applicable LIBOR plus a margin that varies between 1.50% and 2.75% depending on the total leverage ratio. The full principal revolving credit facility included in the Senior Credit Facility will mature on December 27, 2023 or August 6, 2021 if the Term Loan B is not refinanced or repaid in full prior to such date. The interest rate for the Term Loan B is LIBOR plus 2.25%. The Term Loan B requires principal payments of 0.25% of the original principal amount on the last day of each calendar quarter with the full amount maturing on February 2, 2022. The terms of the Senior Credit Facility include customary representations and warranties, customary affirmative and negative covenants and customary events of default. At any time after the occurrence of an event of default under the Senior Credit Facility, the lenders may, among other options, declare any amounts outstanding under the Senior Credit Facility immediately due and payable and terminate any commitment to make further loans under the Senior Credit Facility. The obligations under the Senior Credit Facility are secured by a security interest on substantially all of the assets of GCI Holdings and the subsidiary guarantors, as defined in the Senior Credit Facility, and on the stock of GCI Holdings. As of June 30, 2020, there is $236.4 million outstanding under the Term Loan B, $275.0 million outstanding under the revolving portion of the Senior Credit Facility and $4.0 million in letters of credit under the Senior Credit Facility, which leaves $271.0 million available for borrowing. Wells Fargo Note Payable GCI Holdings issued a note to Wells Fargo that matures on July 15, 2029 and is payable in monthly installments of principal and interest (the "Wells Fargo Note Payable"). The interest rate is variable at one month LIBOR plus 2.25%. The note is subject to similar affirmative and negative covenants as the Senior Credit Facility. The obligations under the note are secured by a security interest and lien on the building purchased with the note. Debt Covenants GCI, LLC is subject to covenants and restrictions under its Senior Notes and Senior Credit Facility. The Company and GCI, LLC are in compliance with all debt maintenance covenants as of June 30, 2020. Fair Value of Debt The fair value of the Senior Notes was $806.0 million at June 30, 2020. Due to the variable rate nature of the Margin Loan, Senior Credit Facility and Wells Fargo Note Payable, the Company believes that the carrying amount approximates fair value at June 30, 2020.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	(9) GCI Liberty has granted to certain directors, employees and employees of its subsidiaries, restricted shares (“RSAs”), restricted stock units (“RSUs”) and options to purchase shares of GCI Liberty’s common stock (collectively, "Awards"). The Company measures the cost of employee services received in exchange for an equity classified Award (such as stock options, RSAs and RSUs) based on the grant-date fair value (“GDFV”) of the Award, and recognizes that cost over the period during which the employee is required to provide service (usually the vesting period of the Award). The Company measures the cost of employee services received in exchange for a liability classified Award based on the current fair value of the Award, and remeasures the fair value of the Award at each reporting date. Included in selling, general and administrative expenses in the accompanying condensed consolidated statements of operations are $4.4 million and $6.8 million of stock-based compensation during the three months ended June 30, 2020, and 2019, respectively, and $6.9 million and $12.4 million during the six months ended June 30, 2020 and 2019, respectively . During the six months ended June 30, 2020, and in connection with our CEO’s new employment agreement, GCI Liberty granted to our CEO 359 thousand options to purchase shares of GCI Liberty Series A common stock as part of our CEO’s upfront term award detailed in his employment agreement. Such options had a GDFV of $16.60 per share and vest on December 31, 2023. Also during the six months ended June 30, 2020, GCI Liberty granted to our CEO 148 thousand options to purchase shares of GCI Liberty Series A common stock in conjunction with our CEO’s annual awards as detailed in his employment agreement. Such options had a GDFV of $13.21 per share and vest on December 31, 2020. Also during the six months ended June 30, 2020, GCI Liberty granted 3 thousand time-based RSUs of GCI Liberty Series A common stock to our CEO. The RSUs had a GDFV of $59.80 per share and cliff vest on December 10, 2020. This RSU grant was issued in lieu of our CEO receiving 50% of his remaining base salary for the last three quarters of calendar year 2020, and he has waived his right to receive the other 50%, in each case, in light of the ongoing financial impact of COVID-19. The Company has calculated the GDFV for all of its equity classified Awards and any subsequent remeasurement of its liability classified Awards using the Black-Scholes-Merton Model. The Company estimates the expected term of the Awards based on historical exercise and forfeiture data. The volatility used in the calculation for Awards is based on the historical volatility of GCI Liberty’s stock and the implied volatility of publicly traded GCI Liberty options. The Company uses a zero dividend rate and the risk-free rate for Treasury Bonds with a term similar to that of the subject options. GCI Liberty-Outstanding Awards The following table presents the number and weighted average exercise price ("WAEP") of Awards to purchase GCI Liberty common stock granted to certain officers, employees and directors of the Company, as well as the weighted average remaining life and aggregate intrinsic value of the Awards. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Series A ​ ​ ​ ​ ​ ​ ​ Weighted ​ Aggregate ​ ​ ​ ​ ​ ​ ​ average ​ intrinsic ​ ​ Awards ​ ​ ​ ​ remaining ​ value ​ (000's) WAEP life (millions) Outstanding at January 1, 2020 604 ​ $ 48.67 ​ Granted 513 ​ $ 67.10 ​ Exercised (29) ​ $ 36.94 ​ Forfeited/Cancelled — ​ $ — ​ Outstanding at June 30, 2020 1,088 ​ $ 57.70 5.2 years ​ $ 15 Exercisable at June 30, 2020 393 ​ $ 47.28 3.7 years ​ $ 9 ​ There were no changes to outstanding options of GCI Liberty Series B common stock during the six months ended June 30, 2020. As of June 30, 2020, the total unrecognized compensation cost related to unvested options and RSA/RSUs was approximately $8.0 million and $16.4 million, respectively. Such amounts will be recognized in the Company’s consolidated statements of operations over a weighted average period of approximately 2.3 years and 2.0 years, respectively. As of June 30, 2020, GCI Liberty had 429 thousand RSUs outstanding. As of June 30, 2020, GCI Liberty reserved for issuance upon exercise of outstanding stock options approximately 1.1 million shares of GCI Liberty Series A common stock and 1.2 million shares of GCI Liberty Series B common stock.

Segment Reporting [Abstract]
Information About the Company's Operating Segments	(11) The Company, through its interests in subsidiaries and other companies, is primarily engaged in the broadband communications services industry. The Company identifies its reportable segments as (A) those consolidated companies that represent 10% or more of its consolidated annual revenue, annual Adjusted OIBDA (as defined below) or total assets and (B) those equity method affiliates whose share of earnings represent 10% or more of the Company’s annual pre-tax earnings. The Company evaluates performance and makes decisions about allocating resources to its operating segments based on financial measures such as revenue, Adjusted OIBDA (as defined below), and subscriber metrics. For the three and six months ended June 30, 2020, the Company has identified the following subsidiary as a reportable segment: ● GCI Holdings - provides a full range of wireless, data, video, voice, and managed services to residential, businesses, governmental entities, and educational and medical institutions primarily in Alaska. For presentation purposes the Company is providing financial information for Liberty Broadband. While the Company’s equity method investment in Liberty Broadband does not meet the reportable segment threshold defined above, the Company believes that the inclusion of such information is relevant to users of these financial statements. ● Liberty Broadband - an equity method affiliate of the Company, accounted for at fair value, has a non-controlling interest in Charter, and a wholly-owned subsidiary, Skyhook Wireless, Inc. ("Skyhook"). Charter is the second largest cable operator in the United States and a leading broadband communications services company providing video, Internet and voice services. Skyhook provides a Wi-Fi based location platform focused on providing positioning technology and contextual location intelligence solutions. The Company’s operating segments are strategic business units that offer different products and services. They are managed separately because each segment requires different technologies, distribution channels and marketing strategies. The accounting policies of the consolidated subsidiaries included in the segments are the same as those described in the Company’s Summary of Significant Accounting Policies in note 2 to the accompanying consolidated financial statements to our Annual Report on Form 10-K for the year ended December 31, 2019. Performance Measures Revenue by segment from contracts with customers, classified by customer type and significant service offerings follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ Six months ended ​ June 30, ​ June 30, ​ ​ 2020 ​ 2019 ​ 2020 ​ 2019 ​ ​ amounts in thousands GCI Holdings ​ ​ ​ ​ ​ ​ ​ Consumer Revenue ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Wireless ​ $ 29,906 ​ 27,505 ​ ​ 58,264 ​ 54,997 Data ​ ​ 45,416 ​ 41,457 ​ ​ 89,710 ​ 82,635 Video ​ ​ 20,456 ​ 21,045 ​ ​ 41,214 ​ 42,061 Voice ​ ​ 3,715 ​ 4,321 ​ ​ 7,515 ​ 8,782 Business Revenue ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Wireless ​ ​ 19,616 ​ 19,393 ​ ​ 38,854 ​ 37,777 Data ​ ​ 72,928 ​ 63,733 ​ ​ 156,322 ​ 131,843 Video ​ ​ 4,427 ​ 3,988 ​ ​ 8,449 ​ 7,813 Voice ​ ​ 7,047 ​ 6,636 ​ ​ 13,463 ​ 12,840 Lease, grant, and subsidies revenue ​ ​ 19,070 ​ 22,901 ​ ​ 40,351 ​ 45,442 Total GCI Holdings ​ ​ 222,581 ​ 210,979 ​ ​ 454,142 ​ 424,190 Corporate and other ​ ​ 2,239 ​ 6,587 ​ ​ 6,477 ​ 11,112 Total ​ $ 224,820 ​ 217,566 ​ ​ 460,619 ​ 435,302 ​ Liberty Broadband revenue totaled $4.1 million and $3.7 million for the three months ended June 30, 2020 and 2019, respectively and $8.2 million and $7.2 million for the six months ended June 30, 2020 and 2019, respectively. ​ The Company had gross receivables of $286.5 million and deferred revenue of $37.3 million at June 30, 2020 from contracts with customers, which amounts exclude receivables and deferred revenue arising from leases, grants, and subsidies. Our customers generally pay for services in advance of the performance obligation and therefore these prepayments are recorded as deferred revenue. The deferred revenue is recognized as revenue in the accompanying condensed consolidated statements of operations as the services are provided. Changes in the contract liability balance for the Company during the three and six months ended June 30, 2020 were not materially impacted by other factors. The Company expects to recognize revenue in the future related to performance obligations that are unsatisfied (or partially unsatisfied) of approximately $148.8 million in the remainder of 2020 2021 2022 2023 2024 The Company applies certain practical expedients as permitted under ASC 606 and does not disclose information about remaining performance obligations that have original expected durations of one year or less, information about revenue remaining from usage based performance obligations that are recognized over time as-invoiced, or variable consideration allocated to wholly unsatisfied performance obligations. For segment reporting purposes, the Company defines Adjusted OIBDA as revenue less cost of sales, operating expenses, and selling, general and administrative expenses (excluding stock-based compensation). The Company believes this measure is an important indicator of the operational strength and performance of its businesses by identifying those items that are not directly a reflection of each business’ performance or indicative of ongoing business trends. In addition, this measure allows management to view operating results and perform analytical comparisons and benchmarking between businesses and identify strategies to improve performance. This measure of performance excludes depreciation and amortization, stock-based compensation, separately reported litigation settlements, insurance proceeds and restructuring and impairment charges that are included in the measurement of operating income pursuant to GAAP. Accordingly, Adjusted OIBDA should be considered in addition to, but not as a substitute for, operating income, net income, cash flow provided by operating activities and other measures of financial performance prepared in accordance with GAAP. Although GCI Liberty owns less than 100% of the outstanding shares of Liberty Broadband, 100% of the Liberty Broadband amounts are included in the tables below and subsequently eliminated in order to reconcile the account totals to the GCI Liberty condensed consolidated financial statements. Adjusted OIBDA is summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ Six months ended ​ ​ ​ June 30, ​ June 30, ​ ​ ​ 2020 ​ 2019 ​ 2020 ​ 2019 ​ ​ ​ amounts in thousands ​ GCI Holdings $ 78,045 ​ 66,121 ​ 164,440 ​ 110,592 Liberty Broadband ​ (7,407) ​ (4,174) ​ ​ (12,388) ​ (7,291) ​ Corporate and other ​ (9,832) ​ (5,511) ​ ​ (20,161) ​ (11,817) ​ ​ ​ 60,806 ​ 56,436 ​ ​ 131,891 ​ 91,484 ​ Eliminate Liberty Broadband ​ 7,407 ​ 4,174 ​ ​ 12,388 ​ 7,291 ​ ​ ​ $ 68,213 ​ ​ 60,610 ​ ​ 144,279 ​ ​ 98,775 ​ ​ Other Information ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2020 ​ ​ ​ Total ​ Investments ​ Capital ​ ​ ​ assets ​ in affiliates ​ expenditures ​ ​ ​ amounts in thousands ​ GCI Holdings $ 3,151,685 475 66,704 Liberty Broadband ​ 12,335,399 12,306,593 35 ​ Corporate and other ​ 8,781,445 166,646 678 ​ ​ ​ 24,268,529 12,473,714 67,417 ​ Eliminate Liberty Broadband ​ (12,335,399) (12,306,593) (35) ​ Consolidated ​ $ 11,933,130 167,121 67,382 ​ ​ The following table provides a reconciliation of Adjusted OIBDA to Operating income (loss) and Earnings (loss) before income taxes: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended Six months ended ​ ​ June 30, ​ June 30, ​ ​ ​ 2020 ​ 2019 ​ 2020 ​ 2019 ​ ​ ​ amounts in thousands ​ Adjusted OIBDA ​ $ 68,213 60,610 ​ ​ 144,279 98,775 ​ Stock‑based compensation ​ (4,393) (6,754) ​ ​ (6,868) (12,385) ​ Depreciation and amortization ​ (61,160) (65,891) ​ ​ (124,168) (133,569) ​ Insurance proceeds and restructuring, net ​ — (4,218) ​ ​ — (1,718) ​ Operating income (loss) ​ 2,660 (16,253) ​ ​ 13,243 (48,897) ​ Interest expense ​ (34,387) (40,386) ​ ​ (70,642) (78,004) ​ Share of earnings (loss) of affiliates, net ​ 2,238 (1,068) ​ ​ 1,531 (4,364) ​ Realized and unrealized gains (losses) on financial instruments, net ​ 860,867 679,098 ​ ​ 26,875 1,688,698 ​ Tax Sharing Agreement ​ 14,444 7,452 ​ ​ 3,911 16,533 ​ Other, net ​ (242) 11,596 ​ ​ 2,138 14,364 ​ Earnings (loss) before income taxes ​ $ 845,580 640,439 ​ ​ (22,944) 1,588,330 ​ (4) ​
