The success of the DOS version of Doom in 1993 and 1994 was overwhelming. The Internet of 1993 (not yet the commercial powerhouse it would later become) had been buzzing about the game. Many users had attained screen shots while others managed to find a full Doom download. The first public version of Doom was released for download on December 10, 1993. This Doom download was known as shareware, which allows users to play part of the game for free, but then requires registration for a price. Doom set a record in shareware downloads, being installed on some ten million home and office computers.
