Organization, Consolidation and Presentation of Financial Statements [Abstract]
Presentation	Presentation—All references to Tribune Media Company or Tribune Company in the accompanying unaudited condensed consolidated financial statements encompass the historical operations of Tribune Media Company and its subsidiaries (collectively, the “Company”). The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial reporting. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the fiscal year ended December 28, 2014 included in the Company’s Annual Report on Form 10-K. In the opinion of management, the financial statements contain all adjustments necessary to present fairly the financial position of the Company as of March 29, 2015 and the results of operations and cash flows for the three months ended March 29, 2015 and March 30, 2014. All adjustments reflected in the accompanying unaudited condensed consolidated financial statements which management believes necessary to present fairly the financial position, results of operations and cash flows, have been reflected and are of a normal recurring nature. Results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. Beginning in fiscal 2015, the Television and Entertainment reportable segment includes the Company’s Zap2it.com entertainment website business, which was previously included in the Digital and Data reportable segment. Certain previously reported amounts have been reclassified to conform to the current presentation; the impact of this reclassification was immaterial. In addition, the accompanying unaudited condensed consolidated financial statements reflect the spin-off of the Company’s principal publishing operations into an independent company which occurred on August 4, 2014, as further described below. On April 16, 2015, the Company’s Board of Directors (the “Board”) approved the change of the Company’s fiscal year end from the last Sunday in December of each year to December 31 of each year and to change the Company’s fiscal quarter end to the last calendar day of each quarter. This change in fiscal year end will be effective with the Company’s second fiscal quarter, which will now end on June 30, 2015. No other significant accounting policies and estimates have changed from those detailed in Note 1 to the Company’s audited consolidated financial statements for the fiscal year ended December 28, 2014.
Changes in Presentation and Reclassifications	The historical results of operations for Tribune Publishing have been reclassified to discontinued operations for all periods presented herein (see Note 2). Unless indicated otherwise, the information in the notes to the accompanying unaudited condensed consolidated financial statements relates to the Company’s continuing operations.
Use of Estimates	Use of Estimates—The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates.
New Accounting Standards	New Accounting Standards—In April 2015, the FASB issued an Accounting Standards Update (“ASU”) No. 2015-05, “Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40).” The amendments in ASU 2015-05 provide guidance to customers about whether a cloud computing arrangement includes a software license. The amendments in ASU 2015-05 are effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. The amendments in ASU 2015-05 may be applied either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. The Company is currently evaluating adoption methods and the impact of adopting ASU 2015-05 on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, “Interest — Imputation of Interest (Subtopic 835-30).” The amendments in ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments. The amendments in ASU 2015-03 should be applied on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. Upon transition, the Company is required to comply with applicable disclosures for the change in accounting principle. The amendments in ASU 2015-03 are effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The Company will be adopting ASU 2015-03 on the first day of the 2016 fiscal year. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements — Going Concern (Subtopic 205-40).” The amendments in ASU 2014-15 require the management of all entities, in connection with preparing financial statements for each annual and interim reporting period, to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The amendments in ASU 2014-15 are effective for the annual period ending after December 15, 2016 and for annual periods and interim periods thereafter. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” The amendments in ASU 2014-09 create Topic 606, Revenue from Contracts with Customers, and supersede the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments in ASU 2014-09 are effective for annual periods beginning after December 15, 2016, including interim periods within that reporting period. However, in April 2015, the FASB issued an exposure draft of a proposed ASU that would delay by one year the effective date of ASU 2014-09 and allow early adoption as of the original public entity effective date. If finalized, the Company could elect to adopt the provisions of ASU 2014-09 starting with the annual period beginning after December 15, 2017. The amendments in ASU 2014-09 may be applied either retrospectively to each prior period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09 at the date of initial application. The Company is currently evaluating adoption methods and the impact of adopting ASU 2014-09 on its consolidated financial statements. In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” The amendments in ASU 2014-08 change the criteria for reporting discontinued operations for all entities. The amendments also require new disclosures about discontinued operations and disposals of components of an entity that do not qualify for discontinued operations reporting. The amendments in ASU 2014-08 should be applied prospectively to all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. The Company adopted ASU 2014-08 effective on the first day of the 2015 fiscal year. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements.
Interest Expense Allocated to Discontinued Operations	Interest expense associated with the Company’s outstanding debt was allocated to discontinued operations based on the ratio of the $275 million cash dividend received from Tribune Publishing to the total outstanding indebtedness under the outstanding credit facilities in effect in each respective period prior to the Publishing Spin-off and totaled $3 million for three months ended March 30, 2014
Amortization of Broadcast Rights Contract Intangible Assets and Liabilities	These intangible liabilities are reclassified as a reduction of broadcast rights assets in the Company’s unaudited condensed consolidated balance sheet as the programming becomes available for broadcast and subsequently amortized as a reduction of programming expenses in the unaudited condensed consolidated statement of operations in accordance with the Company’s methodology for amortizing the related broadcast rights.
Amortization of Basis Difference Relating to Equity Method Investment Fresh-Start Adjustments	The Company amortizes the differences between the fair values and the investees’ carrying values of the identifiable intangible assets subject to amortization and records the amortization (the “amortization of basis difference”) as a reduction of income on equity investments, net in its unaudited condensed consolidated statements of operations.
