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 PowerPoint
Although PowerPoint by this point had become part of the integrated Microsoft Office product, its development remained in Silicon Valley. Succeeding versions of PowerPoint introduced important changes, particularly version 12.0 (2007) which had a very different shared Office "ribbon" user interface, and a new shared Office XML-based file format. This marked the 20th anniversary of PowerPoint, and Microsoft held an event to commemorate that anniversary at its Silicon Valley Campus for the PowerPoint team there. Special guests were Robert Gaskins, Dennis Austin, and Thomas Rudkin, and the featured speaker was Jeff Raikes, all from PowerPoint 1.0 days, 20 years before.
