1979– Visicalc is released by Dan Bricklin. The spreadsheet application is called the first killer app for personal computers. It turned the PC from a hobby to a business tool. Only downfall for Bricklin was he did not patent the system, therefore, clones like SuperCalc, Microsoft’s MultiPlan and Lotus 1-2-3, would show up.
