Achievements: The spreadsheet software Lotus 1-2-3 sold $3 million in orders before it was officially released in 1983. It quickly became the No. 1 application and helped launch the era of the PC. Lotus gave IBM's new personal computer a touch of business necessity, making computers seem practical on an everyday scale. Because Lotus was written in assembly language as opposed to Pascal, Lotus 1-2-3 was considerably faster than any of its spreadsheet competitors. In addition to its speed, it was the integration of graphing and charts that put Lotus 1-2-3 ahead of its rivals.
Today: Lotus 1-2-3 reigned as king of the spreadsheets in the mid-1980s. However, due to technical issues that arose while trying to re-write the program, newer versions of the application either fell through, were delayed, or weren't much different. In the meantime, Microsoft Excel rose in popularity through-out the 1990s and eventually knocked Lotus from the lead. Lotus 1-2-3 made it onto the Windows platform eventually and continues to be sold as a part of the Lotus SmartSuite.
