Bruce Artwick began the development of Flight Simulator in 1977. His company, Sublogic, initially distributed it for various personal computers.[4] In 1981, Artwick was approached by Microsoft's Alan M. Boyd who was interested in creating a "definitive game" that would graphically demonstrate the difference between older 8-bit computers, such as the Apple II, and the new 16-bit computers, such as the IBM PC, still in development. In 1982, Artwick's company licensed a version of Flight Simulator for the IBM PC to Microsoft, which marketed it as Microsoft Flight Simulator 1.00.
