VisiCalc and the Rise of the PC Spreadsheet

The big computer mainframes of the 1960s and even the minicomputers of the time were not accessible enough to provide the type of direct experience needed to play with the numbers by making multiple changes and producing various scenarios that would make the spreadsheets so valuable later on. It was the microprocessor-enabled PCs that made possible the successive lineage of major digital spreadsheet applications – VisiCalc, Lotus 1-2-3, Microsoft’s Excel, and Google Sheets that transformed modern organizational practices.

A First Pre-VisiCalc Attempt at Electronic Spreadsheets

Despite the increasing processing power of the mainframes and minis, and new interactivity due to timesharing and the use of keyboards and cathode ray screens, the use of computerized spreadsheets never increased significantly until the introduction of the personal computer. It was only after the spreadsheet idea was rediscovered in the context of the microprocessing leap made in the next decade that Mattesich’s ideas would be acknowledged.
