Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying unaudited, interim, Consolidated Financial Statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission for quarterly reports. In the opinion of management, these financial statements contain all adjustments (consisting of only normal recurring items) necessary to present fairly the financial position of Lee Enterprises, Incorporated and its subsidiaries (the “Company”) as of December 27, 2020 and our results of operations and cash flows for the periods presented. The Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company's 2020 Annual Report on Form 10-K. Because of seasonal and other factors, the results of operations for the 13 weeks ended December 27, 2020 are not necessarily indicative of the results to be expected for the full year. References to “we”, “our”, “us” and the like throughout the Consolidated Financial Statements refer to the Company. References to “2021”, “2020” and the like refer to the fiscal years ended the last Sunday in September. The Consolidated Financial Statements include our accounts and those of our subsidiaries, all of which are wholly-owned, except for our 82.5% interest in INN Partners, L.C. (“TownNews.com”), 50% interest in TNI Partners (“TNI”) and 50% interest in Madison Newspapers, Inc. (“MNI”). Investments in TNI and MNI are accounted for using the equity method and are reported at cost, plus our share of undistributed earnings since acquisition less, for TNI, amortization of intangible assets.
COVID-19 Pandemic, Policy [Policy Text Block]	COVID-19 Pandemic With the outbreak of COVID-19 and the declaration of a pandemic by the World Health Organization on March 11, 2020, governments implemented a combination of shelter-in-place orders and other recommendations severely limiting or restricting economic activity in our local markets. Certain aspects of our operations have experienced lower revenue and profitability over the last several years and these trends are expected to continue in the future; however, the pandemic and government restrictions caused significant and immediate declines in demand for certain of our products and services, particularly in advertising revenue. The COVID-19 pandemic has had, and the Company expects that it will continue to have, a significant negative near term impact on the Company’s business and operating results. The long-term impact of the COVID-19 pandemic will depend on the length, severity and recurrence of the pandemic, the availability of antiviral medications and vaccinations, the duration and extent of government actions designed to combat the pandemic, as well as changes in consumer behavior, all of which are highly uncertain. Despite the significant negative impacts on our operating results, we have operated uninterrupted in providing local news, information and advertising in our print and digital editions.
Purchase Agreement with Berkshire Hathaway, Policy [Policy Text Block]	Purchase Agreement with Berkshire Hathaway On March 16, 2020, the Company completed the Asset and Stock Purchase Agreement (Purchase Agreement) dated as of January 29, 2020 with Berkshire Hathaway Inc., a Delaware corporation (“Berkshire”) and BH Media Group, Inc., a Delaware corporation (“BHMG”) (the “Purchase Agreement”). As part of the Purchase Agreement, the Company purchased certain assets and assumed certain liabilities of BHMG’s newspapers and related community publications business (“BH Media Newspaper Business”), excluding real estate and fixtures such as production equipment, and all of the issued and outstanding capital stock of The Buffalo News, Inc., a Delaware corporation (“Buffalo News”) for a combined purchase price of $140,000,000 (collectively, the “Transactions”). BHMG includes 30 daily newspapers and digital operations, in addition to 49 paid weekly newspapers with websites and 32 other print products. Buffalo News is a provider of local print and digital news to the Buffalo, NY area. The rationale for the acquisition was primarily the attractive nature of the various publications, businesses, and digital platforms as well as the revenue growth and operating expense synergy opportunities. The Transactions were funded pursuant to a Credit Agreement dated as of January 29, 2020 between the Company and BH Finance LLC, a Delaware limited liability company affiliated with Berkshire (the “Credit Agreement”), as described further in Note 5. Between July 2, 2018 and March 16, 2020, the Company managed the BHMG newspaper business pursuant to a Management Agreement between BHMG and the Company dated June 26, 2018 (“the Management Agreement”). In connection with the Transactions, the Management Agreement terminated on March 16, 2020. As part of the settlement of the preexisting relationship, the Company received $5,425,000 at closing. This amount represents $1,245,000 in fixed fees pro-rated under the contract and $4,180,000 in variable fees based upon the pro-rated annual target. The amount we received settled our existing contract assets balance, which totaled $3,589,000 as of December 29, 2019, and the remaining amount was reflected in Other Revenue for the 13 weeks ended March 29, 2020. The amount of variable fees was estimated based on expected BHMG financial performance through March 16, 2020. Actual financial performance through March 16, 2020 did not vary materially from the estimated amount. As such, the Company did not recognize a gain or loss as a result of the settlement of this preexisting relationship. In connection with the Transactions, the Company also entered into a 10-year term lease with BHMG.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of the Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. We evaluate these estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
Business Combinations Policy [Policy Text Block]	Business Combinations The Company accounts for acquisitions in accordance with the provisions of Accounting Standards Codification 805 “Business Combinations” (“ASC 805”), which provides guidance for recognition and measurement of identifiable assets and goodwill acquired, liabilities assumed, and any noncontrolling interest in the acquiree at fair value. In a business combination, the assets acquired, liabilities assumed and non-controlling interest in the acquiree are recorded as of the date of acquisition at their respective fair values with limited exceptions. Any excess of the purchase price (consideration transferred) over the estimated fair values of net assets acquired is recorded as goodwill. Transaction costs are expensed as incurred. The operating results of the acquired business are reflected in the Company’s Consolidated Financial Statements from the date of the acquisition.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards - Standards Adopted in 2021 In June 2016, the FASB issued a new standard to replace the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a wider array of reasonable and supportable information to inform and develop credit loss estimates. We are required to use a forward-looking expected credit loss model for both accounts receivables and other financial instruments. The new standard was adopted on September 28, 2020 using a modified retrospective approach. This standard did not have a material impact on our Consolidated Financial Statements. *Recently Issued Accounting Standards - Standards Not* Yet Adopted** In August 2018, FASB issued a new standard to amend disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The new standard will be adopted beginning September 27, 2021 using a retrospective approach. The Company is still evaluating the impacts to our financial statement disclosures.
