Inspired by "Colossal Cave", Marc Blank and Dave Lebling created what was to become the first Infocom game, "Zork", in 1977 at MIT's Laboratory for Computer Science. Despite the development of a revolutionary virtual memory system that allowed games to be much larger than the average personal computer's normal capacity, the enormous mainframe-developed game had to be split into three roughly equal parts. "Zork I" was released originally for the TRS-80 in 1980. Infocom was founded on June 22, 1979; the founding members were Tim Anderson, Joel Berez, Marc Blank, Mike Broos, Scott Cutler, Stu Galley, Dave Lebling, J. C. R. Licklider, Chris Reeve, and Al Vezza.
