Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Other Information	Basis of Presentation and Other Information The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X for interim financial information. All normal recurring adjustments considered necessary for a fair presentation have been included. Certain disclosures normally included in annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) have been omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes contained in our Annual Report on Form 10-K for the year ended December 31, 2020. The preparation of the unaudited interim consolidated financial statements requires management of the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingencies at the date of the unaudited interim condensed consolidated financial statements. These estimates are inherently subject to judgment and actual results could differ. Adoption of New Accounting Principles There have been no material developments related to recently issued accounting standards, including the expected dates of adoption and estimated effects on the Company's unaudited condensed consolidated financial statements and note disclosures, from those disclosed in the Company's 2020 Annual Report on Form 10-K, that would be expected to impact the Company.

Discontinued Operations

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On August 26, 2020, Sprint Corporation ("Sprint"), an indirect subsidiary of T-Mobile US, Inc., ("T-Mobile"), on behalf of and as the direct or indirect owner of Sprint PCS, delivered notice to the Company exercising its option to purchase the assets and operations of our Wireless operations for 90% of the “Entire Business Value” (as defined under our affiliate agreement and determined pursuant to the appraisal process set forth therein). Shortly thereafter, the Company committed to a plan to sell the discontinued Wireless operations. The final and binding appraisal process that determined the transaction price was completed on February 1, 2021. Expected sale proceeds are $1.95 billion based upon the appraisal process and other agreements between the parties. The closing of the sale is now expected to occur in the third quarter of 2021, subject to execution of the definitive asset purchase agreement, securing required regulatory approvals and customary closing conditions. The Company and T-Mobile submitted required regulatory filings to the Department of Justice (DOJ), the Federal Communications Commission (FCC), and the Public Service Commission of West Virginia (PSCWV), in March 2021. The premerger notification waiting period under the Hart-Scott Rodino Antitrust Improvements Act of 1976, as amended, expired on April 26, 2021, without the DOJ’s Antitrust Division or the Federal Trade Commission taking any action in connection with the proposed transaction thus allowing the parties to consummate the transaction upon receipt of pending regulatory approvals from the FCC and the PSCWV. The assets and liabilities that are expected to transfer in the sale are presented as held for sale within our unaudited condensed consolidated balance sheets, and discontinued operations within our unaudited condensed consolidated statements of comprehensive income. This disposal group excludes the accounts receivable and certain current liabilities generated by our Wireless operations because they are expected to be settled separately from the sale. Such accounts receivable totaled $49.4 million and $51.7 million at March 31, 2021 and December 31, 2020, respectively, and such current liabilities totaled $4.9 million and $6.1 million at March 31, 2021 and December 31, 2020, respectively. Our identification of assets and liabilities held for sale could change based on the terms of the final asset purchase agreement. The transaction is structured as an asset sale for income tax purposes. As a result, no current or deferred tax assets or liabilities are included within the disposal group. While our long-term debt does not transfer in the sale, its provisions require us to repay all of the debt upon consummation of the sale. Our debt is therefore presented outside of the disposal group as a current liability at December 31, 2020. Our related interest rate swap liabilities are also presented outside of the disposal group as a current liability at December 31, 2020, because management intends to settle them at consummation. Because repayment of the debt is contractually triggered by the sale, the related interest expense is presented within discontinued operations under the relevant authoritative guidance. The carrying amounts of the major classes of assets and liabilities, which are classified as held for sale in the consolidated balance sheets, are as follows: (in thousands) March 31, December 31, ASSETS Inventory $ 3,651 $ 5,746 Prepaid expenses and other 42,942 47,003 Property, plant and equipment, net 299,246 299,647 Intangible assets, net 166,103 176,459 Goodwill 146,383 146,383 Operating lease right-of-use assets 420,410 421,586 Deferred charges and other assets 38,793 36,470 Current assets held for sale $ 1,117,528 $ 1,133,294 LIABILITIES Current operating lease liabilities $ 398,340 $ 409,887 Accrued liabilities and other 10,775 8,770 Asset retirement obligations 33,974 33,545 Current liabilities held for sale $ 443,089 $ 452,202 Income from discontinued operations, net of tax in the consolidated statements of comprehensive income consist of the following: (in thousands) Three Months Ended Revenue: 2021 2020 Service revenue and other $ 100,674 $ 91,388 Equipment revenue 6,399 12,750 Total revenue 107,073 104,138 Operating expenses: Cost of services 19,427 33,439 Cost of goods sold 6,221 12,528 Selling, general and administrative 10,702 8,930 Restructuring expense 211 — Depreciation and amortization — 24,826 Total operating expenses 36,561 79,723 Operating income 70,512 24,415 Other (expense) income: Interest expense (4,384) (6,228) Income before income taxes 66,128 18,187 Income tax expense 17,656 5,057 Income from discontinued operations, net of tax $ 48,472 $ 13,130 Under the relevant authoritative guidance, consummation of the sale will trigger or accelerate the recognition of certain expense related to contingent deal advisory fees, severance costs, recognition of our interest rate swap losses in net income, and loss on debt extinguishment. Our estimate of the related range of reasonably possible expense extends from $0 if the sale is not consummated to $36 million.

Revenue from Contracts with Cus

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Our Broadband segment provides broadband data, video and voice services to residential and commercial customers in portions of Virginia, West Virginia, Maryland, Pennsylvania and Kentucky, via fiber optic, hybrid fiber coaxial cable, and fixed wireless networks. The Broadband segment also provides voice and DSL telephone services to customers in Virginia’s Shenandoah County and portions of adjacent counties as a Rural Local Exchange Carrier (“RLEC”). These contracts are generally cancellable at the customer’s discretion without penalty at any time. We allocate the total transaction price in these transactions based upon the standalone selling price of each distinct good or service. We generally recognize these revenues over time as customers simultaneously receive and consume the benefits of the service, with the exception of equipment sales and home wiring, which are recognized as revenue at a point in time when control transfers and when installation is complete, respectively. Installation fees, charged upfront without transfer of commensurate goods or services to the customer, are allocated to services and are recognized ratably over the longer of the contract term or the period in which the unrecognized fee remains material to the contract, which we estimate to be about one year. Additionally, the Company incurs commission and installation costs related to in-house and third-party vendors which are capitalized and amortized over the expected weighted average customer life which is approximately five years. Our Broadband segment also provides Ethernet and Wavelength fiber optic services to commercial fiber customers under capacity agreements, and the related revenue is recognized over time. In some cases, non-refundable upfront fees are charged for connecting commercial fiber customers to our fiber network. Those amounts are recognized ratably over the longer of the contract term or the period in which the unrecognized fee remains material to the respective contract. A related contract liability of $2.8 million was recognized at March 31, 2021, which we expect to recognize into revenue at the rate of approximately $0.8 million per year. The Broadband segment also leases dedicated fiber optic strands to customers as part of “dark fiber” agreements, which are accounted for as leases under ASC 842, Leases. Our Tower segment leases space on owned cell towers to our Wireless and Broadband segments, and to other wireless carriers. Revenue from these leases is accounted for under ASC 842. Refer to Note 14, Segment Reporting , for a summary of these revenue streams. Below is a summary of the Broadband segment's capitalized contract acquisition and fulfillment costs: Three Months Ended (in thousands) 2021 2020 Beginning Balance $ 14,669 $ 11,005 Contract payments 1,805 1,685 Contract amortization (1,259) (1,027) Ending Balance $ 15,215 $ 11,663

The Company holds the related investments in a rabbi trust as a source of funding for future payments under the plan. The SERP’s investments were designated as trading securities and will be liquidated and paid out to the participants upon retirement. The benefit obligation to participants is always equal to the value of the SERP assets under ASC 710, Compensation . Changes to the investments' fair value are presented in Other income (expense), while the reciprocal changes in the liability are presented in selling, general and administrative expense. At March 31, 2021, an additional $0.8 million of SERP investments were presented as prepaid expenses and other (current assets) as we intend to liquidate certain investments to pay the current portion of our SERP obligation. Cost Method Investments : Our investment in CoBank’s Class A common stock represented substantially all of our cost method investments with a balance of $10.0 million and $9.8 million at March 31, 2021 and December 31, 2020, respectively. We recognized approximately $1.0 million of patronage income in Other income (expense) in both the three months ended March 31, 2021 and 2020. Historically, approximately 75% of the patronage distributions were collected in cash and 25% in equity. Equity Method Investments: At March 31, 2021, the Company had a 20.0% ownership interest in Valley Network Partnership (“ValleyNet”). The Company and ValleyNet purchase capacity on one another’s fiber network. We recognized revenue of $0.2 million from providing service to ValleyNet during both of the three months ended March 31, 2021 and 2020, respectively. We recognized Cost of service of $0.5 million and $0.8 million for the use of ValleyNet’s network during the three months ended March 31, 2021 and 2020, respectively.

The $2.1 million acquisition price was allocated as follows: $1.1 million of property, plant and equipment; $0.4 million to subscriber relationships; and $0.6 million of goodwill. We remitted $1.89 million of the acquisition price at closing. During the third quarter of 2020, the Company completed the purchase of certain indefinite-lived CBRS spectrum licenses for an aggregate cost of $16.1 million, within our Broadband segment. Spectrum licenses in the CBRS band are issued by the Federal Communications Commission (“FCC”) and provide us priority access rights over general access users other than incumbents, in that specific band, in accordance with the FCC’s three-tier CBRS band spectrum sharing framework to utilize designated radio frequency spectrum within specific geographic service areas to provide wireless communication services. For the three months ended March 31, 2021 and 2020, amortization expense was approximately $0.2 million and $0.2 million, respectively.

Leases [Abstract]
Leases	Leases We lease various telecommunications sites, warehouses, retail stores, and office facilities for use in our business. These agreements include fixed rental payments as well as variable rental payments, such as those based on relevant inflation indices. The accounting lease term includes optional renewal periods that we are reasonably certain to exercise based on our assessment of relevant contractual and economic factors. The related lease payments are discounted at lease commencement using the Company's incremental borrowing rate in order to measure the lease liability and ROU asset. The incremental borrowing rate is determined using a portfolio approach based on the rate of interest that the Company would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. The Company uses the observable unsecured borrowing rate and risk-adjusts that rate to approximate a collateralized rate. At March 31, 2021, our operating leases had a weighted average remaining lease term of 22 years and a weighted average discount rate of 4.5%. Our finance leases had a weighted average remaining lease term of 14 years and a weighted average discount rate of 5.2%. During each of the three months ended March 31, 2021 and 2020, we recognized $1.4 million of operating lease expense. We recognized $0.2 million and $0.1 million of interest and depreciation expense on finance leases during the three months ended March 31, 2021 and 2020, respectively. Operating lease expense is presented in cost of service or selling, general and administrative expense based on the use of the relevant facility. Variable lease payments and short-term lease expense were both immaterial. We remitted $1.5 million and $1.0 million of operating lease payments during the three months ended March 31, 2021 and 2020, respectively. We also obtained $2.7 million and $0.3 million of leased assets in exchange for new operating lease liabilities recognized during the three months ended March 31, 2021 and 2020, respectively.

Debt Disclosure [Abstract]
Debt	Debt Our syndicated Credit Agreement includes a $75 million, five-year undrawn revolving credit facility, as well as the following term loans: (in thousands) March 31, December 31, Term loan A-1 $ 222,154 $ 229,437 Term loan A-2 467,234 468,481 689,388 697,918 Less: unamortized loan fees 8,857 9,455 Total debt, net of unamortized loan fees $ 680,531 $ 688,463 Term Loan A-1 bears interest at one-month LIBOR plus a margin of 1.50%, while Term Loan A-2 bears interest at one-month LIBOR plus a margin of 1.75%. LIBOR resets monthly. Our cash payments for interest were $3.9 million and $5.8 million during the three months ended March 31, 2021 and 2020, respectively. As shown below, as of March 31, 2021, the Company was in compliance with the financial covenants in its credit agreements. Actual Covenant Requirement Total leverage ratio 1.8 3.25 or Lower Debt service coverage ratio 7.4 2.0 or Higher Minimum liquidity balance (in millions) $ 304.2 $25.0 or Higher Rate quotations provided by a group of banks that sustain LIBOR will no longer be required after 2021. As a result, it is uncertain whether LIBOR will continue to be quoted after 2021. Our term loans and interest rate swaps identify LIBOR as a reference rate and mature after 2021. Alternative reference rates that replace LIBOR may not yield the same or similar economic results over the terms of the financial instruments. The transition from LIBOR could result in us paying higher or lower interest rates on our current LIBOR-indexed term loans, affect the fair value of the derivative instruments we hold, or affect our ability to effectively use interest rate swaps to manage interest rate risk. Our Credit Agreement includes provisions that provide for the identification of a LIBOR replacement rate. Due to the uncertainty regarding the transition from LIBOR-indexed financial instruments, including when it will happen, and the manner in which an alternative reference rate will apply, we cannot yet reasonably estimate the expected financial impact of the LIBOR transition. As discussed in Note 2, Discontinued Operations , the terms of our long term debt agreements require us to repay all of our debt upon consummation of the sale of our Wireless operations, which is expected to occur during the third quarter of 2021. Management also intends to settle the related interest rate swaps upon consummation. Both are therefore presented outside of the disposal group as a current liability at March 31, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	Derivatives and Hedging The Company's interest rate swaps are pay-fixed (1.16%), receive-variable (one month LIBOR) that hedged approximately 40% of outstanding debt with outstanding notional amounts totaling $275.3 million and $328.7 million as of March 31, 2021 and 2020, respectively. The fair value of these instruments was estimated using an income approach and observable market inputs. The hedge was determined to be highly effective and therefore all of the change in its fair value was recognized through other comprehensive income.
