VisiCalc was the first spreadsheet program, but was not available for CP/M. SuperCalc filled this void. It was originally bundled with WordStar, and became very popular for CP/M and eventually ported over to MS-DOS. It survived into the early 90’s when Microsoft Excel became the defacto spreadsheet program.
