IBM Selectric
The IBM Selectric (a portmanteau of "selective" and "electric") was a highly successful line of electric typewriters introduced by IBM on 31 July 1961.
Instead of the "basket" of individual typebars that swung up to strike the ribbon and page in a typical typewriter of the period, the Selectric had a chrome-plated plastic "element" (frequently called a "typeball", or less formally, a "golf ball") that rotated and tilted to the correct position before striking the paper. The element could be easily interchanged to use different fonts within the same document typed on the same typewriter, resurrecting a capability which had been pioneered by typewriters such as the Hammond and Blickensderfer in the late 19th century.
The Selectric also replaced the traditional typewriter's horizontally moving carriage with a roller (platen) that turned to advance the paper vertically while the typeball and ribbon mechanism moved horizontally across the paper. The Selectric mechanism was notable for using internal mechanical binary coding and two mechanical digital-to-analog converters, called whiffletree linkages, to select the character to be typed.
The three models of Selectric eventually captured 75 percent of the United States market for electric typewriters used in business. By the Selectric's 25th anniversary, in 1986, a total of more than 13 million machines had been made and sold.
By the 1970s and 1980s, the typewriter market had matured under the market dominance of large companies in Europe and the United States. Eventually the Selectric would face direct major competition from electronic typewriters designed and manufactured in Asia, including Brother Industries and Silver Seiko Ltd. of Japan.
IBM replaced the Selectric line with the IBM Wheelwriter in 1984, and spun off its typewriter business to the newly formed Lexmark in 1991.
The Selectric typewriter was introduced on 31 July 1961. Its industrial design is credited to influential American designer Eliot Noyes. Noyes had worked on a number of design projects for IBM; prior to his work on the Selectric, he had been commissioned in 1956 by Thomas J. Watson Jr. to create IBM's first house style: these influential efforts, in which Noyes collaborated with Paul Rand, Marcel Breuer, and Charles Eames, have been referred to as the first "house style" program in American business.
The Selectric remained unchanged until 1971 when the Selectric II was introduced. The original design was thereafter referred to as the Selectric I. These machines used the same 88-character typing elements. However they differed from each other in many respects:
