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.
