VisiCalc, the first #spreadsheet, was the first program that every business not only needed, but instantly knew that it needed! I recall businesspeople in computer stores saying, “I want a #VisiCalc.”

The clerks explained that VisiCalc was a program, and you needed an Apple to run it on. (Bricklin and Frankston wrote VisiCalc on an #Apple because that’s what they happened to have.) “Yeah, yeah, fine, whatever it takes, but I gotta have a VisiCalc.” (j p)
