Microsoft Word is a word processing application of Microsoft Corporation. It was originally written by richard brodie in 1983 for IBM computers running DOS. Subsequent versions can be run on Apple Macintosh (1984), SCO UNIX and Microsoft Windows (1989) and become a part of Microsoft Office. The first generation of Word developed by MS-DOS computer was released at the end of 1983, but the response was poor, and its sales volume lagged behind that of rival products such as WordPerfect. Nevertheless, in the Macintosh system, Word won wide acceptance after the release of 1985, especially the second release of Word 3.0 1 for Macintosh two years later. Like other Mac software, Word for Mac is a real (what you see is what you get) editor.
