VisicalcVisicalc was the program that turned the personal computer into a business machine. Developed by Dan Bricklin and Bob Frankston. Bricklin, while studying his MBA at Harvard came up with the idea when his professors had described to him the large blackboards divided into rows and columns that were used for production planning in companies. Visicalc was the first spreadsheet computer program, originally developed for the Apple II. Soon large companies were buying Apple II’s by the dozen, just to run Visicalc.
