Abstract

The spreadsheet and the personal computer are intrinsically bound. In the early 1980s, the spreadsheet was the first “killer app”—the software application that drove people to buy a personal computer. While specialized computers for word processing were replacing typewriters and database software captured the computing power of mainframes, the spreadsheet allowed managers to track, analyze, and model decisions, especially financial decisions, using a tool with low barriers to entry on an affordable computer.
