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.
Office Assistant
First introduced in Microsoft Office 97, the Office Assistant was codenamed TFC during development. It appeared when the program determined the user could be assisted with using Office wizards, searching help, or advising users on using Office features more effectively. It also presented tips and keyboard shortcuts. For example, typing an address followed by "Dear" would cause the Assistant to appear with the message, ""It looks like you're writing a letter. Would you like help?"".
