Infocom (1979)
The MIT Intellect, the Z-Machine Virtual Engine, and the Golden Age of Interactive Fiction
Incorporated on June 22, 1979, by ten MIT Computer Science staff and students in Cambridge, Massachusetts, Infocom reigned as the undisputed literary master of interactive fiction and text adventures. Leveraging their sophisticated natural language parser and cross-platform Z-Machine virtual interpreter, Infocom produced enduring literary milestones including the Zork trilogy, Douglas Adams' The Hitchhiker's Guide to the Galaxy, and Planetfall, pioneering tactile 'feelies' packaging.
MIT Hackers and the Full-Sentence Parser
Dissatisfied with the crude two-word verb-noun parser of Crowther and Woods' Colossal Cave, MIT researchers Dave Lebling and Marc Blank engineered an English parser capable of processing compound prepositions and indirect objects ('Hit the troll with the elvish sword then open chest'). The subterranean labyrinth of Zork entered gaming folklore, introducing the immortal gaming phrase: 'It is pitch black. You are likely to be eaten by a grue.'
The Z-Machine Virtual Machine and the Cornerstone Debacle
Infocom resolved the 1980s computer fragmentation crisis by inventing the Z-Machine—an early bytecode virtual machine. The game source was compiled into platform-agnostic Z-code, running identically on Apple II, Commodore 64, Atari 800, and IBM PC with minimal porting. To deter pirating, Infocom bundled lavish physical artifacts ('feelies') inside game boxes. However, catastrophic R&D losses on the 'Cornerstone' business database software forced an acquisition by Activision in 1986.
