The first of the legally licensed commercial adaptations began in 1985 for the BBC Micro, Amstrad CPC and ZX Spectrum. Over the years, Monopoly has been released for different operating systems on the PC and Macintosh platforms. At the time, Parker Brothers was unaware of this distribution until a user informed them of one version that stated 'A Parker Brother game' on the title screen the company then began enforcing its copyright and trademark on Monopoly. Many unlicensed, non-commercial computer games based on Monopoly were distributed on bulletin board systems, public domain software disks and academic computer systems, and appeared as early as the late 1970s.
