How many of you have used an electronic spreadsheet,
like Microsoft Excel? Very good.
Now how many of you have run a business with a spreadsheet by hand,
like my dad did for his small printing business in Philadelphia?
A lot less. Well, that's the way it was done for hundreds of years.
In early 1978, I started working on an idea that eventually became VisiCalc.
And the next year it shipped running on something new
called an Apple II Personal Computer.
