Now being called AppleWorks, is a light version of MS Office. However, it is not meant to replace MS Office, instead just deliver light and packed with most used features office suite. Bundled with every new Macintosh computer.
Before ClarisWorks, in the days of Apple II, this wonderful office suite was called... AppleWorks for the first time.
