Dave Lebling and Marc Blank were students at MIT's Laboratory for Computer Science when they discovered Crowther and Woods' Adventure.[45] Together with Tim Anderson and Bruce Daniels they began to develop a similar game, Zork, which also started life on a PDP-10 minicomputer and was distributed across the ARPANET. On graduation the students, together with their group leader Albert Vezza, decided to form a company to market Zork for home computers,[45] and on 22 June 1979 Tim Anderson, Joel Berez, Marc Blank, Mike Broos, Scott Cutler, Stu Galley, Dave Lebling, J. C. R. Licklider, Chris Reeve, and Albert Vezza incorporated Infocom.[46]
The developers faced the same difficulties as Scott Adams in porting Zork to microcomputers: The PDP-10 version, which would reach a megabyte in size, was enormous for the time, and the Apple II and the TRS-80, the potential targets, each had only 16 kb of RAM. They solved this problem by breaking up the game into three episodes, and developing ZIL (Zork Implementation Language), which could function on any computer by using Infocom's Z-machine, the first virtual machine used in a commercial product,[47] as an intermediary.
In November 1980 the new Zork I: The Great Underground Empire was made available for the PDP-11; One month later, it was released for the TRS-80, with more than 1,500 copies sold between that date and September 1981. That same year, Bruce Daniels finalized the Apple II version and more than 6,000 additional copies were sold. Zork I would go on to sell over a million copies.
The company continued developing text adventure games even as it opened a department for the development of professional software, a department which would never be profitable. High-quality games, with massive, intelligent plots, unequaled syntax analyzers, and meticulous documentation as integral parts of the game, succeeded in all genres.
The writer Douglas Adams produced two games with Infocom, the first based on his popular Hitchhiker's Guide to the Galaxy series and a lesser known adventure game called Bureaucracy, inspired by the difficulties he encountered in moving houses.
With the power of microcomputers increasing and the demand for graphics (which it refused to include in its games until 1987), Infocom saw sales decline and in 1989, having been swallowed up by Activision in 1986, the Infocom division had shrunk to a mere ten employees, compared to 100 at its peak. Although later titles were marketed under the Infocom brand, the Infocom division was shut down, and games developed after 1989 would have no link with the original team.
The demise of Infocom signalled the end of the commercial age of Interactive Fiction, and text parsers were rarely seen in games after 1989. Despite this, the low barrier to entry has ensured that a vibrant and creative community of IF authors continues to thrive on the Internet, using languages such as Inform, which generates files that can be read by Infocom's own Z-machine.
