What Happened to VisiCalc?
The 1979 spreadsheet that was the personal computer's first killer app — a landmark that Lotus 1-2-3 soon overtook.
VisiCalc, released in 1979 for the Apple II, was the first spreadsheet program and the PC's first killer app, pushing businesses to buy personal computers. As Lotus 1-2-3 took over the business market in the 1980s, VisiCalc faded and was eventually discontinued.
The first spreadsheet
VisiCalc was created by Dan Bricklin and Bob Frankston and released by their company Software Arts in 1979. It was the first electronic spreadsheet, and it let people set up a grid of numbers, type in relationships between cells, and watch results recalculate instantly — something paper and calculators could never do.
The killer app
VisiCalc is considered the personal computer's first killer app. Its usefulness was so obvious that businesses bought Apple II computers specifically to run it, and the program proved that a personal computer could be a serious business tool. It helped define the idea that software could sell hardware.
Overtaken by Lotus 1-2-3
Software Arts could not hold its lead. Competitors rose, and Lotus 1-2-3 captured the business spreadsheet market in the 1980s with a faster, more powerful package. VisiCalc's market share collapsed, and the program was discontinued.
Where VisiCalc is now
VisiCalc is no longer a working product and is long obsolete. Its place in history, though, is secure: it created an entire software category and demonstrated that a spreadsheet could make the personal computer indispensable, a legacy that shapes the productivity software we still use today.
