Document Summary
Programs to manipulate spreadsheets were among the first applications to earn the title killer app, since they demonstrated that computers could be used effectively by those who were not expert computer scientists. The first successful spreadsheet program was visicalc, invented by dan bricklin and bob frankston (harvard business school) in 1978. Visicalc provided automation for common paper-based accounting practices, as do all spreadsheet programs that came after it. Therefore accountants and other financial officers were familiar with the user interface and found it natural to enter data and formulas and interpret the output that was presented. Soon others found the simplicity of working with rows and columns of data convenient for many diverse applications, and spreadsheet programs grew in popularity. Today spreadsheet software is a part of every collection of productivity tools. Some examples of spreadsheet software are excel (from microsoft), quattro pro (from. Corel), lotus 1-2-3 (from ibm), and calc (from openoffice. org).
