Microsoft Office is an office suite of applications, servers, and services developed by Microsoft. It was first announced by Bill Gates on 1 August 1988, at COMDEX in Las Vegas. Initially a marketing term for a bundled set of 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 10 July 2012, Softpedia reported that Office is used by over a billion people worldwide.
Office is produced in several versions targeted towards different end-users and computing environments. The original, and most widely used version, is the desktop version, available for PCs running the Windows and macOS operating systems. The most current desktop version is Office 2016 for Windows and macOS, released on 22 September 2015 and 9 July 2015, respectively.
More recently, Microsoft developed Office Mobile, which are free-to-use versions of Office applications for mobile devices. Microsoft also produces and runs Office Online, a web-based version of core Office apps, which is included as part of a Microsoft account.

Microsoft Word is a word processor available for Windows and macOS (formerly known as OS X). Word is also included in some editions of the now discontinued Microsoft Works. The first version of Word, released in the autumn of 1983, was for the MS-DOS operating system and had the distinction of introducing the mouse to a broad population. Word 1.0 could be purchased with a bundled mouse, though none was required. Following the precedents of LisaWrite and MacWrite, Word for Macintosh attempted to add closer WYSIWYG features into its package. Word for Mac was released in 1985. Word for Mac was the first graphical version of Microsoft Word.
Its proprietary Doc format is a de facto standard, although Word 2007 deprecated this format in favor of Office Open XML, which was later standardized by Ecma International as an open format. Support for Portable Document Format (PDF) and OpenDocument (ODF) was first introduced in Word for Windows with Service Pack 2 for Word 2007.
Microsoft Excel is a spreadsheet program that originally competed with the dominant Lotus 1-2-3, and eventually outsold it. It is available for the Windows and macOS platforms. Microsoft released the first version of Excel for the Mac OS in 1985, and the first Windows version (numbered 2.05 to line up with the Mac and bundled with a standalone Windows run-time environment) in November 1987.
Microsoft PowerPoint is a presentation program for Windows and macOS. It is used to create slideshows, composed of text, graphics, and other objects, which can be displayed on-screen and shown by the presenter or printed out on transparencies or slides.
