Visicalc (from English visible calculator ) was the first commercial spreadsheet program for personal and home computers . It was first launched in 1979 for the Apple II by Personal Software . The concept comes from Dan Bricklin , the software was developed together with Bob Frankston . For the first time, the program made it possible to carry out commercial calculations without requiring the user to have any programming knowledge. Portings also appeared later for Apple III , for Atari 400 and 800 , the Commodore PET , TRS-80 and finally for Intel-8086 -based computers from IBM.
history
On May 12, 1979, Dan Bricklin introduced a pre-release spreadsheet on the Apple II at the West Coast Computer Faire . In October 1979 the software was published under the name VisiCalc and was a selling point for the Apple calculator.
In 1983, sales of Visicalc collapsed with the release of Lotus 1-2-3 . Visicalc was later acquired by Lotus 1-2-3 and discontinued shortly afterwards.
