Microsoft Office
Microsoft Office is a family of client software, server software, and services developed by Microsoft. It was first announced by Bill Gates on August 1, 1988, at COMDEX in Las Vegas. Initially a marketing term for an office suite (bundled set of productivity applications), the first version of Office contained Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. Over the years, Office applications have grown substantially closer with shared features such as a common spell checker, OLE data integration and Visual Basic for Applications scripting language. Microsoft also positions Office as a development platform for line-of-business software under the Office Business Applications brand. On July 10, 2012, Softpedia reported that Office is used by over a billion people worldwide.

Microsoft has changed its sales approach in the past years with the introduction of Office 365 in 2011 (June 28). It abandoned the traditional one-time purchase in favor of a regular (monthly or yearly) subscription for many of its offerings, all including the Office 365 label. In addition to the regular Office applications, Office 365 includes cloud-based tools (software as a service), and is sold as a monthly or annual subscription.
