Desktop publishing
Before the advent of desktop publishing, the only option available to most persons for producing typed (as opposed to handwritten) documents was a typewriter, which offered only a handful of typefaces (usually fixed-width) and one or two font sizes.  Indeed, one popular desktop publishing book was actually titled The Mac is not a typewriter. The ability to create WYSIWYG page layouts on screen and then print pages containing text and graphical elements at crisp 300 dpi resolution was revolutionary for both the typesetting industry and the personal computer industry. Newspapers and other print publications made the move to DTP-based programs from older layout systems in the 1980s.
