The IBM Selectric typewriter (occasionally known as the IBM Golfball typewriter) is an influential electric typewriter design. It was introduced in 1961.
Instead of a "basket" of pivoting typebars the Selectric had a pivoting type element (frequently called a "typeball") that could be changed so as to display different fonts in the same document, resurrecting a capacity that had been pioneered by the unsuccessful Blickensderfer typewriter sixty years before. The Selectric also replaced the traditional typewriter's moving carriage with a paper roller ("platen") that stayed stationary while the typeball and ribbon mechanism moved from side to side.
Selectrics and their descendants eventually captured 75 percent of the United States market for electric typewriters.

In 1964 IBM brought out the MT/ST (Magnetic Tape/Selectric Typewriter), which combined the features of the Selectric with a magnetic tape drive. Magnetic tape was the first reusable storage medium for typed information. With this, for the first time, typed material could be edited without having to retype the whole text or chop up a coded copy. On the tape, information could be stored, replayed (that is, retyped automatically from the stored information), corrected, reprinted as many times as needed, and then erased and reused for other projects. This development marked the beginning of word processing as it is known today.
It also introduced word processing as a definite idea and concept. The term was first used in IBM's marketing of the MT/ST as a "word processing" machine. It was a translation of the German word textverabeitung, coined in the late 1950s by Ulrich Steinhilper, an IBM engineer. He used it as a more precise term for what was done by the act of typing. IBM redefined it "to describe electronic ways of handling a standard set of office activities -- composing, revising, printing, and filing written documents."
Since the invention of the MT/ST, advances in technology have made word processing systems less expensive to produce, leading to intensified competition among developers and an increase in the development rate of new packages.
In 1969 IBM introduced MagCards, magnetic cards that were slipped into a box attached to the typewriter and recorded text as it was typed on paper. The cards could then be used to recall and reprint text. These were useful mostly to companies which sent out large numbers of form letters. However, only about one page-worth of text could be stored on each card.
