Spreadsheet
In 1969, a program called LANPAR was created. It was like a digital table that could do math on big computers shared by many people. They named it LANPAR because those words meant something special. Then, in 1979, a similar program called VisiCalc was made for smaller computers. This helped make the Apple II computer really popular. Before Windows became common, a program called Lotus 1-2-3 was the most popular for working with these digital tables. But now, Microsoft Excel is the most used one on Windows and Mac computers. These digital table programs are now found in programs that help people do work in offices. In 2006, Google made their own digital table program that you can use on the internet. It's called Google Sheets and is part of Google Drive.
