Microsoft

Microsoft is a leading global vendor of computer software; hardware for computer, mobile and gaming systems; and cloud services. Microsoft’s corporate headquarters is located in Redmond, Wash., and it has offices in more than 60 countries.

Microsoft’s roots go back at least as far as 1975, when the first commercially available personal computer appeared on the cover of Popular Electronics magazine. The Altair 8800 was a rudimentary system, but it found a market for home-based computers and created a new demand for software to use with these systems.
