VisiCorp is better known for VisiCalc. Launched for the Apple II in 1979, this was the first spreadsheet program for personal computers. Later, VisiCalc was supplanted by Lotus 1-2-3, as developed by MIT laureate Mitch Kapor - before 1-2-3 was outcompeted by Excel. It was very rudimentary indeed, but it was transformative and created an entirely new category of software.
