Infocom is one of the early developers and publishers of interactive fiction (aka text adventure games) including the phenomenally popular and influential Zork series of games as well as many others, including Planetfall, Hitchhiker's Guide to the Galaxy, and Leather Goddesses of Phobos, among many others. They were acquired by Activision after a failed business venture into productivity software (a database called Cornerstone) left them heavily in debt.
