When Apple developed its forward-looking Macintosh computer in the early 1980s to combat the IBM PC, which was out-pacing the Apple II, Microsoft was one of the early believers in the new vision. Gates took a chance on Jobs' graphical users interface and agreed to be one of the early application developers. The result was Microsoft Word, which would eventually be one of the computing world's most popular applications. Gates said, "One of the most fun things we did was the Macintosh and that was so risky. People may not remember that Apple really bet the company." Of course, the collaboration on the Macintosh also led to Microsoft developing its own competing platform, Windows, which later became the source of the bitter rivalry between the two companies.
