Improv was another attempt to move beyond the basic spreadsheet model. Pioneered by an advanced technology group within Lotus in 1985, the goal was to make spreadsheets not necessarily easier to use, but easier to create. As with Javelin, Lotus developers separated the components of the spreadsheet -- the data from the cells and the formulas. Steve Jobs was an admirer, and Improv became one of the most popular applications on Next computers. A Windows version arrived in 1993, but it was just too different from what people expected from a spreadsheet. Nevertheless, a derivative of Improv called Quantrix is still used in financial environments.
