Hasbro is an American toy and game company and is the second-largest toy maker in the world, second only to the toy giant Mattel. The company's corporate headquarters are located in Pawtucket, Rhode Island.
Only one known Star Trek-related product was produced directly by Hasbro which was the Star Trek Game that was released in 1974. In 2011, Hasbro released four Mr. Potato Head toy versions of Kirk, Kor, Spock, and Uhura under their PPW Toys brand.
Hasbro is currently the parent company of such brands as Milton Bradley, Parker Brothers, South Bend, Palitoy, Tiger Electronics, Wizards of the Coast, and Galoob. They have licensed several of these properties to other companies (notably USAopoly and Fundex) which have produced Star Trek-themed versions of their games.
