Infocom's Z-machine was introduced to the world in the July 1980 Creative Computing article "How to Fit a Large Program into a Small Machine" by Marc Blank and Stu Galley. The term "interactive fiction" hadn't been coined yet, so they called the genre "CFS" (Computerized Fantasy Simulation). Despite basically inventing the form, they didn't make fetch happen. https://mud.co.uk/richard/htflpism.htm
