A Timeline of Spreadsheet History
1961 - Professor Richard Mattessich was the first to develop a computerized spreadsheet.
1978 - Robert Frankston & Dan Bricklin invented VisiCalc, the first spreadsheet. It came out with the Apple II computer. VisiCalc did very well in its first year because it could run. On personal computers, could perform simple math formulas, and gave immediate results.
1980 - DIF formats were invented. Data was more portable and could be shared with other programs.
1980-83 - New versions of DIF, SuperCalc, and some other programs came out to the public.
1983 - Lotus 123 was introduced. It allowed people to chart information and identify cells. For example cell A1.
1985 - Lotus 123 number 2.
1987 - New spreadsheet programs such as Excel and Corel Quattro Pro were introduced. This allowed people to add graphics. They are different because they include graphic capabilities.
2001 - Spreadsheet programs in use today are Excel, Appleworks, and Corel Quattro Pro.

Excel - Software developed and manufactured by Microsoft Corporation that allows users to organize, format, and calculate data with formulas using a spreadsheet system broken up by rows and columns. Microsoft Excel usually comes bundled with Microsoft Office and is compatible with other applications offered in the suite of products.
AppleWorks - An earlier integrated software package from Apple for the Mac and Windows. It was introduced in 1991 for the Mac as ClarisWorks (from Apple's Claris subsidiary) and included word processing, spreadsheet, database, drawing, painting and communications functions. Quite popular, a Windows version followed two years later.
Corel Quattro Pro - A Windows spreadsheet from Corel that provides advanced graphics and presentation capabilities, including goal seeking, 3D graphing and the ability to create multi-layered slide shows. It is optionally keystroke compatible with Lotus 1-2-3. Quattro Pro was originally developed by Borland, then purchased by Novell in 1994 and Corel in 1996. Quattro Pro was sold as a separate package (Corel Quattro Pro) for a while, but is now part of Corel's WordPerfect Office suites.
