Accounting Policies [Abstract]
Basis of Presentation	In the opinion of management, the accompanying unaudited interim consolidated financial statements contain all normal and recurring adjustments necessary to present fairly the consolidated financial position of Hasbro, Inc. and all majority-owned subsidiaries ("Hasbro" or the "Company") as of March 29, 2020 and March 31, 2019, and the results of its operations and cash flows and shareholders' equity for the periods then ended in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and notes thereto. Actual results could differ from those estimates.
Production Financing	Production Financing Production financing relates to financing facilities for certain of the Company's television and film productions. Beginning in the first quarter of 2020 with the acquisition of eOne, the Company funded certain of its television and film productions using production financing facilities. Production financing facilities are secured by the assets and future revenues of the individual production subsidiaries, typically have maturities of less than two years while the titles are in production, and are repaid once the production is delivered and all tax credits, broadcaster pre-sales and international sales have been received. In connection with the production of a television or film program, the Company records initial cash outflows within cash flows from operating activities due to its investment in the production and concurrently records cash inflows within cash flows from financing activities from the production financing it normally obtains. Under these facilities, certain of the Company's cash is restricted while the financing is outstanding. At March 29, 2020, $86,177 of the Company's cash was restricted by such facilities.
Investment in Productions and Acquired Content Rights	Investment in Productions and Acquired Content Rights The cost of investments in programming ("IIP") and investments in content rights ("IIC") for eOne's television and film libraries are recorded in the consolidated balance sheets at amounts considered recoverable against future revenues. These amounts are amortized to program cost amortization using a model that reflects the consumption of the asset as it is released through different exploitation windows (e.g., broadcast licenses, theatrical release and home entertainment) and the expected revenue earned in each of those stages of release over a period not exceeding 10 years. Amounts capitalized are reviewed regularly and any portion of the unamortized amount that appears not to be recoverable from future net revenues will be written off to program cost amortization during the period in which the loss becomes evident. Certain of these agreements require the Company to pay minimum guaranteed advances ("MGs") for participations and residuals. MGs are recognized in the consolidated balance sheets when a liability arises, usually on delivery of the television or film program to the Company. The current portion of MGs are recorded as Payables and Accrued Liabilities and the long-term portion are recorded as Other Liabilities. These consolidated financial statements have been prepared without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Certain information and disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations.
Recently Adopted Accounting Standards and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Standards The Company's significant accounting policies are the same as those described in Note 1 to the Company's consolidated financial statements in its 2019 Form 10-K with the exception of the accounting policies disclosed above. In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2016-13 (ASU 2016-13) Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in this update provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The standard update replaces the 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 inform credit loss estimates. For public companies, this standard is effective for annual reporting periods beginning after December 15, 2019, and early adoption was permitted. The Company adopted the standard in the first quarter of 2020 and the adoption of the standard did not have a material impact on its consolidated financial statements. In August 2018, the FASB issued Accounting Standards Update No. 2018-13 (ASU 2018-13), Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, specifically related to disclosures surrounding Level 3 asset balances, fair value measurement methods, related gains and losses and fair value hierarchy transfers. For public companies, this standard is effective for annual reporting periods beginning after December 15, 2019, and early adoption was permitted. The Company adopted the standard in the first quarter of 2020 and the adoption of the standard did not have a material impact on its consolidated financial statements. In March 2019, the FASB issued Accounting Standards Update No. 2019-02 (ASU 2019-02) Entertainment-Films-Other Assets-Film Costs (Subtopic 926-20) and Entertainment-Broadcasters-Intangibles-Goodwill and Other (Subtopic 920-350): Improvements to Accounting for Costs of Films and License Agreements for Program Materials. The amendments in this update align cost capitalization of episodic television series production costs with that of film production cost capitalization. In addition, this update addresses impairment testing procedures with regard to film groups, when a film or license agreement is expected to be monetized with other films and/or license agreements. The intention of this update is to align accounting treatment with changes in production and distribution models within the entertainment industry and to provide increased transparency of information provided to users of financial statements about produced and licensed content. For public companies, this standard is effective for annual reporting periods beginning after December 15, 2019, and early adoption was permitted. The Company adopted the standard in the first quarter of 2020 and the adoption of the standard did not have a material impact on its consolidated financial statements. Recently Issued Accounting Pronouncements In August 2018, the FASB issued Accounting Standards Update No. 2018-14 (ASU 2018-14) Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. The amendments in this update modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. For public companies, this standard is effective for annual reporting periods beginning after December 15, 2020, and early adoption is permitted. The standard relates to financial statement disclosure only and will not have an impact on the Company's consolidated statement of financial position, statements of operations and comprehensive earnings (loss) or statement of cash flows.
Revenue Recognition	Revenue Recognition Revenue is recognized when control of the promised goods or content is transferred to the customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for transferring those goods or content. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. Contract Assets and Liabilities Within our Entertainment, Licensing and Digital segment and our eOne segment the Company may receive royalty payments from licensees in advance of the licensees’ subsequent sales to their customers, or in advance of the Company’s performance obligation being satisfied. In addition, the Company may receive payments from its digital gaming business in advance of the recognition of the revenues. The Company defers revenues on these advanced payments until its performance obligation is satisfied and records the aggregate deferred revenues as liabilities. The Company records contract assets in the case of minimum guarantees that are being recognized ratably over the term of the respective license periods which varies based on sales over and above the contracts’ minimum guarantee. The current portion of contract assets were recorded in Prepaid Expenses and Other Current Assets, respectively, and the long-term portion were recorded as Other Long-Term Assets. Disaggregation of revenues The Company disaggregates its revenues from contracts with customers by segment: U.S. and Canada, International, Entertainment, Licensing and Digital, and eOne. The Company further disaggregates revenues within its International segment by major geographic region: Europe, Latin America, and Asia Pacific. Finally, the Company disaggregates its revenues by brand portfolio into five brand categories: Franchise brands, Partner brands, Hasbro gaming, Emerging brands, and TV/Film/Entertainment. We believe these collectively depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.
Leases	The Company occupies offices and uses certain equipment under various operating lease arrangements. The Company has no finance leases. These leases have remaining lease terms of 1 to 18 years, some of which include options to extend lease terms or options to terminate current lease terms at certain times, subject to notice requirements set out in the lease agreement. Payments under certain of the lease agreements may be subject to adjustment based on a consumer price index or other inflationary indices. The lease liability for such lease agreements as of the adoption date, was based on fixed payments as of the adoption date. Any adjustments to these payments based on the related indices will be recorded to expense as incurred. Leases with an expected term of 12 months or less are not capitalized. Lease expense under such leases is recorded straight line over the life of the lease. The Company capitalizes non-lease components for equipment leases, but expenses non-lease components as incurred for real estate leases.

The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable.

Contract Assets and Liabilities

Within our Entertainment, Licensing and Digital segment and our eOne segment the Company may receive royalty payments from licensees in advance of the licensees’ subsequent sales to their customers, or in advance of the Company’s performance obligation being satisfied. In addition, the Company may receive payments from its digital gaming business in advance of the recognition of the revenues. The Company defers revenues on these advanced payments until its performance obligation is satisfied and records the aggregate deferred revenues as liabilities. The Company records contract assets in the case of minimum guarantees that are being recognized ratably over the term of the respective license periods which varies based on sales over and above the contracts’ minimum guarantee. The current portion of contract assets were recorded in Prepaid Expenses and Other Current Assets, respectively, and the long-term portion were recorded as Other Long-Term Assets.

The Company disaggregates its revenues from contracts with customers by segment: U.S. and Canada, International, Entertainment, Licensing and Digital, and eOne. The Company further disaggregates revenues within its International segment by major geographic region: Europe, Latin America, and Asia Pacific. Finally, the Company disaggregates its revenues by brand portfolio into five brand categories: Franchise brands, Partner brands, Hasbro gaming, Emerging brands, and TV/Film/Entertainment. We believe these collectively depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.

The Company occupies offices and uses certain equipment under various operating lease arrangements. The Company has no finance leases. These leases have remaining lease terms of 1 to 18 years, some of which include options to extend lease terms or options to terminate current lease terms at certain times, subject to notice requirements set out in the lease agreement.

The lease liability for such lease agreements as of the adoption date, was based on fixed payments as of the adoption date. Any adjustments to these payments based on the related indices will be recorded to expense as incurred. Leases with an expected term of 12 months or less are not capitalized. Lease expense under such leases is recorded straight line over the life of the lease. The Company capitalizes non-lease components for equipment leases, but expenses non-lease components as incurred for real estate leases.
