Microsoft PowerPoint or just PowerPoint is a presentation program by Microsoft. It is part of the Microsoft Office suite, and runs on Microsoft Windows and Apple's Mac OS X operating system.
PowerPoint is used by business people, educators, students, and trainers. From Microsoft Office 2003 to 2008 for Mac, Microsoft revised the branding to emphasize PowerPoint's place within the office suite, calling it Microsoft Office PowerPoint instead of just Microsoft PowerPoint. The current versions are Microsoft PowerPoint 2010 for Windows and Microsoft Office PowerPoint 2008 for Mac.
History
The original version of this program was created by Dennis Austin and Thomas Rudkin of Forethought, Inc.. Originally designed for the Macintosh computer, the initial release was called "Presenter". In 1987, it was renamed to "PowerPoint" due to problems with trademarks, the idea for the name coming from Robert Gaskins. In August of the same year, Forethought was bought by Microsoft for $14 million USD ($26.8 million in present-day terms, and became Microsoft's Graphics Business Unit, which continued to further develop the software.
PowerPoint changed significantly with PowerPoint 97. Prior to PowerPoint 97, presentations were linear, always proceeding from one slide to the next. PowerPoint 97 incorporated the Visual Basic for Applications (VBA) language, underlying all macro generation in Office 97, which allowed users to invoke pre-defined transitions and effects in a non-linear movie-like style without having to learn programming (or even having to be aware of the existence of VBA).
PowerPoint 2000 (and the rest of the Office 2000 suite) introduced a clipboard that could hold multiple objects at once. Another noticeable change was that the Office Assistant, whose frequent unsolicited appearances in PowerPoint 97 (as an animated paperclip) had annoyed many users, was changed to be less intrusive.
