Summary of Significant Accounting Policies (Policies)	Jun. 30, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation — The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The interim financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto included in our 2015 Annual Report on Form 10-K. In management's opinion, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the interim periods have been made. Results of operations are not necessarily indicative of the results that may be expected for future interim periods or for the full year. Certain amounts in prior periods have been reclassified to conform to the current period's presentation.
Nature of Operations	Nature of Operations — We are a diverse media enterprise with a portfolio of television, radio and digital media brands. All of our media businesses provide content and advertising services via digital platforms, including the Internet, smartphones and tablets. Our media businesses are organized into the following reportable business segments: television, radio, digital, and syndication and other. Additional information for our business segments is presented in the Condensed Notes to Consolidated Financial Statements. On April 1, 2015, we distributed our newspaper business to our shareholders in a tax-free spin-off. See Note 17 for information on the spin-off.
Use of Estimates	Use of Estimates — Preparing financial statements in accordance with accounting principles generally accepted in the United States of America requires us to make a variety of decisions that affect the reported amounts and the related disclosures. Such decisions include the selection of accounting principles that reflect the economic substance of the underlying transactions and the assumptions on which to base accounting estimates. In reaching such decisions, we apply judgment based on our understanding and analysis of the relevant circumstances, including our historical experience, actuarial studies and other assumptions. Our financial statements include estimates and assumptions used in accounting for our defined benefit pension plans; the periods over which long-lived assets are depreciated or amortized; the fair value of long-lived assets, goodwill and indefinite lived assets; the liability for uncertain tax positions and valuation allowances against deferred income tax assets; the fair value of assets acquired and liabilities assumed in business combinations; and self-insured risks. While we re-evaluate our estimates and assumptions on an ongoing basis, actual results could differ from those estimated at the time of preparation of the financial statements.
Revenue Recognition	Revenue Recognition — We recognize revenue when persuasive evidence of a sales arrangement exists, delivery occurs or services are rendered, the sales price is fixed or determinable and collectability is reasonably assured. When a sales arrangement contains multiple elements, such as the sale of advertising and other services, we allocate revenue to each element based upon its relative fair value. We report revenue net of sales and other taxes collected from our customers. Our primary sources of revenue are from the sale of broadcast and digital advertising, as well as retransmission fees received from cable operators and satellite carriers. The revenue recognition policies for each source of revenue are described in our 2015 Annual Report on Form 10-K.
Share-Based Compensation	Share-Based Compensation — We have a Long-Term Incentive Plan (the “Plan”) which is described more fully in our Annual Report on Form 10-K for the year ended December 31, 2015. The Plan provides for the award of incentive and nonqualified stock options, stock appreciation rights, restricted stock units (RSUs), unrestricted Class A Common shares and performance units to key employees and non-employee directors. Share-based compensation costs totaled $2.2 million and $5.2 million for the second quarter of 2016 and 2015, respectively. Year-to-date share-based compensation costs totaled $7.2 million and $7.1 million in 2016 and 2015, respectively, of which $1.1 million for 2015 is included in discontinued operations.
Earnings Per Share (EPS)	Earnings Per Share (“EPS”) — Unvested awards of share-based payments with rights to receive dividends or dividend equivalents, such as our RSUs, are considered participating securities for purposes of calculating EPS. Under the two-class method, we allocate a portion of net income to these participating securities and therefore exclude that income from the calculation of EPS for common stock. We do not allocate losses to the participating securities.
Derivative Financial Instruments	Derivative Financial Instruments — It is our policy that derivative transactions are executed only to manage exposures arising in the normal course of business and not for the purpose of creating speculative positions or trading. Derivative financial instruments are utilized to manage interest rate risks. We do not hold derivative financial instruments for trading purposes. All derivatives must be recorded on the balance sheet at fair value. Each derivative is designated as a cash flow hedge or remains undesignated. Changes in the fair value of derivatives that are designated and effective as cash flow hedges are recorded in other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transactions affected earnings. These changes are offset in earnings to the extent the hedge was effective by fair value changes related to the risk being hedged on the hedged item. Changes in the fair value of undesignated hedges are recognized currently in earnings. All ineffective changes in derivative fair values are recognized currently in earnings. All designated hedges are formally documented as to the relationship with the hedged item as well as the risk-management strategy. Both at inception and on an ongoing basis, the hedging instrument is assessed as to its effectiveness, when applicable. If and when a derivative is determined not to be highly effective as a hedge, the underlying hedged transaction is no longer likely to occur, the hedge designation is removed, or the derivative is terminated, the hedge accounting discussed above is discontinued.

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
