VisiCalc /vi'zi-calk/

<application, tool, business, history> The first spreadsheet program, conceived in 1978 by Dan Bricklin, while he was an MBA student at Harvard Business School. Inspired by a demonstration given by Douglas Engelbart of a point-and-click user interface, Bricklin set out to design an application that would combine the intuitiveness of pencil and paper calculations with the power of a programmable pocket calculator. Bricklin's design was based on the (paper) financial spreadsheet, a kind of document already used in business planning. (Some of Bricklin's notes for VisiCalc were scribbled on the back of a spreadsheet pad.) VisiCalc was probably not the first application to use a spreadsheet model, but it did have a number of original features, all of which continue to be fundamental to spreadsheet software. These include point-and-type editing, range replication, and formulas that update automatically with changes to other cells. VisiCalc is widely credited with creating the sudden demand for desktop computers that helped fuel the microcomputer boom of the early 1980s. Thousands of business people with little or no technical expertise found that they could use VisiCalc to create sophisticated financial programs. This makes VisiCalc one of the first killer apps.

VisiCalc

VisiCalc ("visible calculator") is the first spreadsheet computer program for personal computers, originally released for Apple II by VisiCorp on October 17, 1979. It is considered the killer application for the Apple II, turning the microcomputer from a hobby for computer enthusiasts into a serious business tool, and then prompting IBM to introduce the IBM PC two years later. More than 700,000 copies were sold in six years, and up to 1 million copies over its history.

Initially developed for the Apple II computer using a 6502 assembler running on the Multics time sharing system, VisiCalc was ported to numerous platforms, both 8-bit and some of the early 16-bit systems. To do this, the company developed porting platforms that produced bug compatible versions. The company took the same approach when the IBM PC was launched, producing a product that was essentially identical to the original 8-bit Apple II version. Sales were initially brisk, with about 300,000 copies sold.

VisiCalc uses the A1 notation in formulas.

When Lotus 1-2-3 was launched in 1983, taking full advantage of the expanded memory and screen of the PC, VisiCalc sales ended almost overnight. Sales declined so rapidly that the company was soon insolvent. Lotus Development purchased the company in 1985, and immediately ended sales of VisiCalc and the company's other products.
