Online Office - Spreadsheets
Spreadsheets transformed the world of business and personal finance when VisiCalc — the first electronic spreadsheet — launched in 1979 for the Apple II. It was the original killer app that turned personal computers from hobbyist toys into serious busi ness tools. Lotus 1-2-3 followed in 1983, and Microsoft Excel dethroned them all in the late 1980s. Today, spreadsheets have moved to the cloud.
