Microsoft PowerPoint 365 Online

Microsoft PowerPoint is a presentation program,[4] created by Robert Gaskins and Dennis Austin at a software company named Forethought, Inc. PowerPoint was originally designed to provide visuals for group presentations within business organizations, but has come to be very widely used in many other communication situations, both in business and beyond. The impact of this much wider use of PowerPoint has been experienced as a powerful change throughout society, with strong reactions including advice that it should be used less, should be used differently, or should be used better.
