"The game that will consume your life"
id Software released the first episode of Doom as free shareware distributed via FTP on university servers, generating word-of-mouth on a scale that no advertising budget could have achieved and effectively demonstrating the internet as a mass distribution channel.
Doom's December 10, 1993 release was not a retail launch — it was a file posted to an FTP server at the University of Wisconsin at midnight, and to America Online simultaneously. The download traffic was so heavy that the university server was overwhelmed within hours. Players who downloaded the free first episode — "Knee Deep in the Dead" — were incentivised to share it with others, and the file moved through university networks, bulletin board systems, and early internet infrastructure at a rate that id Software had not anticipated. The registered three-episode version was sold by mail order at $40; within weeks of the shareware release, id was processing thousands of orders daily. Total Doom installations were estimated at 10 million within two years of release — a figure that no retail game of the era approached. The campaign demonstrated that the internet could distribute software at a scale and speed that made traditional retail almost irrelevant.
