Expensive Typewriter, written and improved between 1961 and 1962 by Steve Piner and L. Peter Deutsch, was a text editing program that ran on a DEC PDP-1 computer at MIT. Since it could drive an IBM Selectric typewriter (a letter-quality printer), it may be considered the first word processing program, but the term "word processing" itself was only introduced, by IBM's Böblingen Laboratory in the late 1960s.
