“Freshen up your formulas and pamper those pivot tables—International Spreadsheet Day is Oct. 17.
On this day in 1979, a computer program called VisiCalc first shipped for the Apple II, marking the birth of the electronic spreadsheet. A few years later, Lotus 1-2-3 for the IBM PC had its moment, and then Microsoft Excel became the dominant spreadsheet program, which it remains today.
The spreadsheet was the original killer app—the thing that convinced many people to buy a computer for the first time. Conceived as a simple scratchpad, the now-ubiquitous tool is used to compile everything from grocery lists to multinational company accounts. Its incredible flexibility makes it both powerful and dangerous, loved and loathed in equal measure.”
Love to know if you were ever a VisiCalc user. 🙂
