Introduced in 1961 by IBM, the first typewriter to use a golf ball-like type element that moved across the paper, rather than moving the paper carriage across the print mechanism. Allowing different fonts to be used by switching balls, it rapidly became one of the world's most popular typewriters. IBM always excelled in electromechanical devices. In 1991, IBM's typewriter division was spun off into Lexmark International. See typewriter.
