After MacWrite, Word for Macintosh never had any serious rivals, although programs such as Nisus Writer provided features such as non-continuous selection, which were not added until Word 2002 in Office XP.
Randy Wigginton was one of Apple Computer's first employees (#6), creator of MacWrite, Full Impact, and numerous other Mac applications.
When Apple stopped bundling MacWrite, ownership was transferred to Claris, so developers could not distribute it on their programs' installation floppy disks.
From the MicroSetter product line evolved the T-Script PostScript interpreter (also referred to in the industry as a Raster image processor) which converted output from popular PostScript based WYSIWYG (What You See Is What You Get) programs such as PageMaker, Microsoft Word and MacWrite to non PostScript printers which were much more economical at the time.
