How did Hasbro come to acquire Parker Brothers and the rights to Monopoly?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Hasbro came to own Parker Brothers—and with it the Monopoly franchise—through a chain of corporate acquisitions culminating in Hasbro’s 1991 purchase of Tonka Corporation, which at that time included the Parker Brothers unit; after the deal Hasbro consolidated Parker Brothers into its Milton Bradley division and absorbed the Monopoly trademarks and publishing rights [1] [2] [3]. Key antecedents include Parker Brothers’ earlier sales to General Mills in 1968 and subsequent corporate restructurings that left the company bundled with Kenner and Tonka before Hasbro’s bid [4] [5] [6].
1. From a Salem game maker to corporate asset: Parker Brothers’ ownership trail
Parker Brothers began as an independent game company in 1883 and rose to prominence with titles such as Monopoly, but its independent era ended when General Mills bought the firm in 1968; General Mills later merged Parker with its Kenner toy unit, creating Kenner Parker Toys, which was acquired by Tonka in 1987—placing Parker Brothers inside a chain of consumer‑products owners long before Hasbro entered the picture [3] [4] [5].
2. Hasbro’s strategic play: acquiring Tonka to buy brands, not factories
Hasbro’s 1991 acquisition of Tonka was a strategic deal to add iconic toy and game lines—including Tonka trucks, Kenner’s properties and Parker Brothers’ catalog (Monopoly among them)—to Hasbro’s portfolio; contemporary accounts and company histories report the purchase price in the roughly half‑billion dollar range, though sources cite slightly different figures ($486 million and about $516 million) for the transaction [2] [3] [6] [1].
3. How Monopoly’s rights moved with Parker Brothers
Monopoly’s commercial rights had been held by Parker Brothers since the mid‑1930s after the company entered into agreements with Charles Darrow and others to publish the game, and those rights transferred to Hasbro automatically when Parker Brothers became part of Hasbro’s corporate structure via the Tonka acquisition; legal history shows Parker (and its parent companies) defended the MONOPOLY trademark over decades, and Hasbro inherited those registrations and litigation responsibilities [7] [8].
4. Post‑acquisition consolidation and brand fate
After the 1991 deal Hasbro merged Parker Brothers into its larger games group—pairing it operationally with Milton Bradley, moving production and later consolidating brands under the Hasbro Games/Hasbro Gaming umbrella—and over time retired the Parker trade name while continuing to publish classic titles such as Monopoly under Hasbro’s corporate brand [1] [3] [9].
5. Competing narratives and what the sources show (and don’t)
Public histories and encyclopedias consistently report that Hasbro acquired Parker Brothers via the Tonka purchase in 1991 and that Monopoly’s rights moved with that acquisition, but they differ on precise purchase‑price figures and emphasize slightly different corporate steps—some sources list $486 million while others report around $516 million—so the record supports the acquisition chain while leaving minor financial details variably reported across accounts [2] [3] [6] [1].
