VisiCalc introduced electronic spreadsheets to the workplace, but it was an innovative program developed by Mitch Kapor in 1983 that revealed the far-reaching capabilities of spreadsheet software. Within seven years, Kapor's original eight person company had almost 3,000 employees and revenues of over half a billion dollars a year.
