VisiCalc

    It made Apple a serious platform for doing business.
  • Dan Bricklin, an MBA student, had an “Aha” moment when he noticed his professor teaching “What-if”.
    Every time one or more variables changed, the professor had to erase and write equations.
    He felt that the process can be done easily with an interactive electronic spreadsheet.
  • Bob Frankston had worked on business oriented programs (e.g. report generators) on the mainframe computers.
  • Dan and Bob founded Software Arts to develop VisiCalc.

VisiCalc was challenged by SuperCalc and numerous other programs that offered improvements.

    (a) Spread sheet
    (b) Graphs
    (c) Data Management.
