Apple Computer, Inc was incorporated in early 1977, and within a few months the two-man company, consisting of Wozniak and his partner, Steve Jobs, released a second machine, the Apple II. The company's early strength was in software: with an open architecture platform, the Apple II won popularity among business customers for running the first office spreadsheet program, called VisiCalc. The Apple II also sported a color screen and hard disk drives, as opposed to the then-popular tape drives and grayscale displays. Yet even as the first platform with a useful office app, Apple was still the third-place computer maker, trailing Tandy and Commodore.
