VisiCalc /vi'zi-calk/

(application, tool, business, history)The first spreadsheetprogram, conceived in 1978 by Dan Bricklin, while he was anMBA student at Harvard Business School. Inspired by ademonstration given by Douglas Engelbart of apoint-and-click user interface, Bricklin set out to designan application that would combine the intuitiveness ofpencil and paper calculations with the power of aprogrammable pocket calculator.

Bricklin's design was based on the (paper) financialspreadsheet, a kind of document already used in businessplanning. (Some of Bricklin's notes for VisiCalc werescribbled on the back of a spreadsheet pad.) VisiCalc wasprobably not the first application to use a spreadsheet model,but it did have a number of original features, all of whichcontinue to be fundamental to spreadsheet software. Theseinclude point-and-type editing, range replication, andformulas that update automatically with changes to othercells.

VisiCalc is widely credited with creating the sudden demandfor desktop computers that helped fuel the microcomputerboom of the early 1980s. Thousands of business people withlittle or no technical expertise found that they could useVisiCalc to create sophisticated financial programs. Thismakes VisiCalc one of the first killer apps.
