Zork was developed on MIT's ITS operating system for the PDP-6 and PDP-10 mainframe computers, between 1977 and 1978 by MIT university students Dave Lebling, Bruce Daniels, Marc Blank, and Tim Anderson. It was shared over the ARPANET, the precursor of the Internet. However, when three of the four designers of Zork formed Infocom, it was split into three text adventure games so that it could be released commercially on the personal computer hardware of the time.
