History
Microsoft was founded on April 4, 1975 by Bill Gates and to develop a  interpreter for the. Microsoft's current CEO is, who succeeded in 2014.

Apple and Microsoft
Microsoft and Apple have long been partners and rivals in the industry and switched places as the world's on multiple occasions.

Microsoft's first project at Apple Computer was adapting its version of BASIC, which superseded Steve Wozniak's Integer BASIC to become Applesoft BASIC for the Apple II plus computer, which was released in April 1979. In 1983, Apple co-founder Steve Jobs invited Bill Gates to preview the pre-release development of the Macintosh. In 1984, Microsoft began development on Microsoft Word 1.0 for Macintosh, which was released in the following year. After Jobs was forced out and Microsoft had released Windows 2.0 with a GUI that was similar to the Mac, Apple Computer, under CEO John Sculley, filed a in 1988 against Microsoft.

Despite the ongoing lawsuit, Apple and Microsoft announced a joint effort in September 1989 to develop alternative printing systems to Adobe Systems' PostScript, such as TrueType. The companies intended to incorporate TrueType into new imaging technologies, such as Apple's QuickDraw GX and Microsoft's. John Warnock, who was the CEO of Adobe at the time, distraughtly called it "the biggest bunch of garbage mumbo jumbo I've ever heard in my life". Adobe responded by developing Adobe Type Manager to maintain the presence of its Type 1 fonts in the desktop computer market. However, when Apple was financially struggling in 1996, Adobe teamed up with Microsoft to develop OpenType as a successor to TrueType.

After Steve Jobs returned to Apple, he negotiated an end to the lawsuits with Microsoft and agreed to cross-license technology between the two companies in exchange for Microsoft's commitment to continue developing software such as Microsoft Office for the Mac and an investment of $150 million in Apple non-voting stock. Apple also agreed to include the Microsoft Internet Explorer web browser by default with future Mac OS releases for the next 5 years. Though the joint announcement by Jobs and Gates was met with shock at Macworld Expo Boston in 1997, the investment from Microsoft helped save Apple from bankruptcy.

Macintosh Business Unit
The Macintosh Business Unit (MacBU) was established in 1997 to focus existing development teams on software for the resurgent Mac platform under Steve Jobs. In December 2002, Roz Ho was appointed as the general manager of the unit, which at the time was the largest Mac-development team outside of Apple Computer.

Apple Platform Experiences
Around early 2014, the Macintosh Business Unit was reorganized into Apple Productivity Experiences (APEX) to reflect that Apple's mobile operating platforms (iOS, and later iPadOS) had grown to surpass the Mac.

Microsoft Stores
Microsoft opened its own chain of Microsoft Stores in an effort to re-create the shopping experience and success of Apple's retail stores. However, after taking a pre-tax loss of $450 million during the COVID-19 pandemic, Microsoft announced on June 26, 2020 that it would shutter all but four of its retail stores permanently. The remaining flagship stores in ; ; and  would be converted into "experience centers".
