Microsoft PowerPoint is a presentation software application developed by the software company Microsoft. It is a standalone application, as well as part of the Microsoft Office suite of applications. It is currently available for both Mac and Windows.

PowerPoint was originally developed for the Macintosh Platform, which is owned by Apple. It was first developed in 1984 and was called "Presentation" at the time. Then, in 1987 its name was changed to "PowerPoint" to avoid trademark conflicts with another existing product. The company that did the initial development was called Forethought Inc. and it was bought out by Microsoft in the August of 1987. Henceforth it was known as the Microsoft Graphics Business Unit. The development of the then newly renamed PowerPoint has continued in to present times.

PowerPoint is used extensively in offices, schools, seminars and anywhere where a slideshow presentation is to be made. It has become the de facto digital slideshow making and editing application even though other major companies have similar applications such as Keynotes from Apple.
