Accounting Policies [Abstract]
Principles of Consolidation	The accompanying consolidated financial statements were prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, in the opinion of management, include all normal and recurring adjustments necessary to present fairly the results of the interim periods shown. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such SEC rules and regulations. Management believes that the disclosures made are adequate to make the information presented not misleading. As described below, as a result of the application of fresh start accounting and the effects of the implementation of the Company's Plan of Reorganization (as defined below), the consolidated financial statements after the Effective Date (as defined below), are not comparable with the consolidated financial statements on or before that date. The financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2019 Annual Report on Form 10-K. The Company’s reportable segments are: ▪Audio, which provides media and entertainment services via broadcast and digital delivery, and also includes the Company’s events and national syndication businesses and ▪Audio & Media Services, which provides other audio and media services, including the Company’s media representation business, Katz Media Group (“Katz Media”) and the Company's provider of scheduling and broadcast software, Radio Computing Services (“RCS”). The consolidated financial statements include the accounts of the Company and its subsidiaries. Also included in the consolidated financial statements are entities for which the Company has a controlling interest or is the primary beneficiary. Investments in companies which the Company does not control, but exercises significant influence over operating and financial policies of the company are accounted for under the equity method. All significant intercompany transactions are eliminated in the consolidation process.
Reclassifications	ReclassificationsCertain prior period amounts have been reclassified to conform to the 2020 presentation. In the first quarter of 2020, in connection with a reorganization of the Company’s management structure after the Separation and emergence from the Chapter 11 cases, the Company reevaluated the classification of certain expenses to determine whether such expenses should be included within Direct operating expenses, Selling, general & administrative (“SG&A”) expenses or Corporate expenses. As a result, certain expenses were reclassified from Corporate expenses to Direct operating or SG&A expenses. In addition, certain expenses were reclassified from SG&A expenses to Direct operating expenses. The reclassifications had no impact on the Company's Operating Income (Loss) or Net Income (Loss). Accordingly, the Company recast the corresponding amounts in the prior period to conform to the current expense classifications. The corresponding current and prior period segment disclosures were recast to reflect the current expense classifications.
New Accounting Pronouncements Recently Adopted	New Accounting Pronouncements Recently Adopted During the second quarter of 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and finalized amendments to FASB ASC Subtopic 825-15, Financial Instruments-Credit Losses ("ASC 326"). The amendments of ASU 2016-13 are intended to provide financial statement users with more decision-useful information related to expected credit losses on financial instruments and other commitments to extend credit by replacing the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to determine credit loss estimates. The amendments of ASU 2016-13 eliminate the probable initial recognition threshold and, in turn, reflect an entity’s current estimate of all expected credit losses. ASU 2016-13 does not specify the method for measuring expected credit losses, and an entity is allowed to apply methods that reasonably reflect its expectations of the credit loss estimate. Additionally, the amendments of ASU 2016-13 require that credit losses on available for sale debt securities be presented as an allowance rather than as a write-down. The Company adopted the updated guidance in the first quarter of 2020 utilizing the modified retrospective approach, which resulted in the recognition of estimated credit loss reserves against certain available-for-sale debt securities from third-parties held by the Company. Upon adoption, the Company recognized a $1.5 million cumulative-effect adjustment to opening retained earnings to reflect expected credit losses in relation to notes receivable held by the Company. In addition, the Company evaluated the potential impact of the COVID-19 pandemic on the collectability of its notes receivable from third-parties. To develop an estimate of the present value of expected cash flows of notes receivable, the Company used a probability-weighted discounted cash flow model. As a result of this analysis, the Company recognized an additional credit loss reserve against available-for-sale debt securities of $5.6 million, which was recognized within Loss on investments, net in the Company's Statement of Comprehensive Loss for the nine months ended September 30, 2020. The Company will continue to actively monitor the impact of the COVID-19 pandemic on expected credit losses. The FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). The new guidance simplifies the accounting for income taxes by eliminating certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, hybrid taxes and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. For public companies, the amendments in this ASU are effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. Early adoption is permitted in interim or annual periods with any adjustments reflected as of the beginning of the annual period that includes that interim period. Additionally, entities that elect early adoption must adopt all the amendments in the same period. Amendments are to be applied prospectively, except for certain amendments that are to be applied either retrospectively or with a modified retrospective approach through a cumulative effect adjustment recorded to retained earnings. The Company early adopted this standard, which did not have significant impact on our financial position, results of operations or cash flows. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This guidance provides temporary optional expedients and exceptions to accounting guidance on contract modifications and hedge accounting to ease entities’ financial reporting burdens as the market transitions from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The guidance was effective upon issuance and generally can be applied through December 31, 2022. The adoption of this standard did not have a significant impact on our financial position, results of operations or cash flows.
