Zork was one of the first adventure games, after ADVENT.

The first version of Zork was written 1977-1979 on a PDP-10 computer by [Tim Anderson]?, [Marc Blank]?, [Bruce Daniels]?, and [Dave Lebling]? in a programming language called MDL?. All the programmers came from the [Dynamic Modelling Group]? at the [MIT Artificial Intelligence Lab]?.

Originally "Zork" was a name that any unfinished program around MIT got. When the game was finished the implementors called it Dungeon?, but people went on calling it Zork, so the name stuck.

The company [Personal Software]? produced a version of Zork I (about the first third of the original Zork) for the Apple II and TRS-80 personal computers in 1980. They had plans to release Zork II as well, but never got that far.

Finally Infocom, a company started by the above and others to produce adventure games brought out versions of Zork for most popular computers.

The Zork series of games introduced grues and zorkmids.

Zork and its relatives fit into a category known as interactive fiction.
