Spreadsheets

Harvard MBA student Dan Bricklin develops the first spreadsheet program to edit, delete, and recalculate numbers in a digital format. The result is a simple, elegant solution to an age-old problem. By the fall of 1979, Bricklin's VisiCalc spreadsheet program is available for Apple II, TRS-80, Commodore PET, and Atari 800 computers and sells for $100.
