Microsoft PowerPoint (full name Microsoft Office PowerPoint) is a ubiquitous presentation program developed for the Microsoft Windows and Mac OS computer operating systems. Being widely used by businesspeople, educators, and trainers, it is among the most prevalent forms of persuasion technology.
In Microsoft Office PowerPoint, as in most other presentation software, text, graphics, movies, and other objects are positioned on individual pages or "slides". The "slide" analogy is a reference to the slide projector, a device which has become somewhat obsolete due to the use of PowerPoint and other presentation software. Slides can be printed, or (more often) displayed on-screen and navigated through at the command of the presenter. Slides can also form the basis of webcasts.
