In 1991, Hasbro acquired Parker Bros. and thus "Monopoly". Before the Hasbro acquisition, Parker Bros. acted as a publisher only issuing two versions at a time, a regular and deluxe. Hasbro moved to create and license many other versions of "Monopoly" and sought public input in varying the game. A new wave of licensed products began in 1994, when Hasbro granted a license to USAopoly to begin publishing a San Diego Edition of "Monopoly", which has since been followed by more than a hundred more licensees including Winning Moves Games (since 1995) and Winning Solutions, Inc. (since 2000) in the United States.
