<span class="mw-page-title-main">History of Microsoft Word</span>

The first version of Microsoft Word was developed by Charles Simonyi and Richard Brodie, former Xerox programmers hired by Bill Gates and Paul Allen in 1981. Both programmers worked on Xerox Bravo, the first WYSIWYG word processor. The first Word version, Word 1.0, was released in October 1983 for Xenix and MS-DOS; it was followed by four very similar versions that were not very successful. The first Windows version was released in 1989, with a slightly improved interface. When Windows 3.0 was released in 1990, Word became a huge commercial success. Word for Windows 1.0 was followed by Word 2.0 in 1991 and Word 6.0 in 1993. Then it was renamed to Word 95 and Word 97, Word 2000 and Word for Office XP. With the release of Word 2003, the numbering was again year-based. Since then, Windows versions include Word 2007, Word 2010, Word 2013, Word 2016, and most recently, Word for Office 365.
