Množina: Lotus 1-2-3s
An electronic spreadsheet product introduced in 1983 by Lotus Development Corporation. Notable for its inclusion of graphing and data-management (database) capabilities in addition to spreadsheet functionality, Lotus 1-2-3 is important in the history of the personal computer because it was one of the first “killer apps” that convinced businesses to buy and use a PC. Lotus Development was purchased by IBM in 1995. See also killer app.
