IBM LOTUS 123 PC
This included the IBM PC when it launched in 1981, where it quickly became another best-seller, with an estimated 300,000 sales in the first six months on the market. VisiCalc's runaway success on the Apple led to direct bug compatible ports to other platforms, including the Atari 8-bit family, Commodore PET and many others. The application was so compelling that there were numerous stories of people buying Apple II's to run the program. Compared to earlier programs, VisiCalc allowed one to easily construct free-form calculation systems for practically any purpose, the limitations being primarily memory and speed related. VisiCalc was launched in 1979 on the Apple II and immediately became a best-seller. IBM purchased Lotus and continued sales, only officially ending sales in 2013. As the early 1990s ended, 1-2-3 was in the number three position, and never recovered. None of these companies had seriously considered the graphical user interface in the DOS era, and responded slowly to Microsoft's own products, Excel and Word. It was not until the acceptance of Windows 3.0 started to grow that the market began to change. 1-2-3 quickly overtook VisiCalc, as well as MultiPlan and SuperCalc, two VisiCalc competitors.ฤก-2-3 was the de-facto standard throughout the 1980s and into the 1990s, part of a triumvirate of products that included dBASE and Word Perfect to build a complete small business platform. Lotus' solution was marketed as a three-in-one solution, handing spreadsheet calculations, charting and database functionality - thus the name "1-2-3". With IBMs entry into the market, VisiCalc was slow to respond, and when they did they launched what was essentially a straight port of their existing system in spite of the greatly expanded hardware capabilities. The first spreadsheet, Visicalc, had helped launch the Apple II as one of the earliest personal computers in business use. It was the IBM PC's first " killer application" its huge popularity in the mid-1980s contributed significantly to the success of the IBM PC in the corporate environment.
