Lotus Improv 1.0

Improv is a spreadsheet program that attempted to re-imagine how one would create and interact with spreadsheets. It was first released in 1991 for NeXT computers, and for a time became one of the NeXT's "Killer Apps". In 1993 Lotus released Improv 2.0 for Microsoft Windows. It was not marketed as a direct replacement to Lotus 1-2-3, and 1-2-3 remained dominant until both were overtaken by Microsoft Excel.
