Infocom was a software company that was founded in 1979 by Massachusetts Institute of Technology staff and students led by Dave Lebling, Marc Blank, Albert Vezza, and Joel Berez. They became famous for their text adventures such as the Zork series.
In 1986, Activision purchased Infocom. They closed the Infocom division in 1989, but released the graphic adventure game Return to Zork in 1993 under the Infocom name.
