In the late 1970s and early 1980s electronic spreadsheet programs became important tools for computer-assisted reporting.
Two of the first programs were VisiCalc and Lotus 1-2-3.
The introduction of VisiCalc came in 1979.
Lotus 1-2-3‘s original release date was 32 years ago today, on January 26, 1983.
Another spreadsheet you may have heard of, Microsoft’s Excel, appeared two years later.
The following video describes Lotus 1-2-3 and its early success with the IBM personal computer.
“Credit for the invention of the spreadsheet goes to Dan Bricklin and Bob Frankston, who created VisiCalc for the Apple II. VisiCalc required 32k of memory to run. A chart from a roundup of spreadsheets in the 1982 Personal Computing magazine lists eighteen spreadsheets. Most ran on either the Apple II or on machines with the CP/M operating system.
….In January 1983, Lotus introduced Lotus 1-2-3 at a price of $495. It was immediately acknowledged to be a better product than VisiCalc.
