Microsoft Works originated as MouseWorks, an integrated spreadsheet, word processor and database program, designed for the Macintosh by ex-Apple employee Don Williams and Rupert Lissner. Works was smaller, less expensive, and had fewer features than Microsoft Office and other major office suites available at the time. Because of its low cost ($40 retail, or as low as $2 OEM), companies frequently pre-installed Works on their low-cost machines. Works was available as a standalone program, and as part of a namesake home productivity suite. Later versions had a calendar application and a dictionary while older releases included a terminal emulator. Its core functionality included a word processor, a spreadsheet and a database management system. Microsoft Works was a productivity software suite developed by Microsoft, sold from 1987 to 2009.
