Microsoft Word is named for its primary function related to text processing, while Excel and PowerPoint have names that reflect their intended use and branding strategy. Excel, derived from the verb "to excel," suggests high performance and superiority in spreadsheet tasks. PowerPoint evokes imagery of effective presentations, with "power" indicating strength and impact. The evolution of word processing began with programs like WordStar and Word Perfect, leading to Microsoft Word's dominance in the market. Similarly, the spreadsheet category started with VisiCalc and progressed through various iterations before Excel emerged, originally designed for Macintosh before transitioning to Windows. Brand names in software are carefully selected to avoid conflicts and convey positive associations with the product.
