A popular software application developed by Microsoft, PowerPoint is widely used for creating presentations and slideshows. It allows users to design and structure slides with text, images, graphics, and multimedia elements such as videos and audio. PowerPoint presentations are commonly used in business, education, and various other settings to convey information in a visually engaging and organized manner.
History and Development
Microsoft PowerPoint, or simply PowerPoint, is a presentation program developed by Microsoft. It was originally created by Robert Gaskins, Tom Rudkin, and Dennis Austin at a software company named Forethought, Inc. It was released on April 20, 1987, initially for Macintosh computers only. Microsoft acquired PowerPoint for about $14 million three months after it appeared. This was Microsoft's first significant acquisition, and Microsoft set up a new business unit for PowerPoint in Silicon Valley where Forethought had been located. PowerPoint became a component of the Microsoft Office suite, first offered in 1989 for Macintosh and in 1990 for Windows, which bundled several Microsoft apps. Beginning with PowerPoint 4.0 (1994), PowerPoint was integrated into Microsoft Office development, and adopted shared common components and a converged user interface.
File Extensions
The files created using PowerPoint have the .ppt or .pptx file extension:
- PPT: This is the file extension used for presentations created in older versions of Microsoft PowerPoint, primarily in versions prior to PowerPoint 2007. PPT files are in a binary file format and may contain macros and embedded objects.
- PPTX: PPTX is the file extension for presentations created in newer versions of Microsoft PowerPoint, starting from PowerPoint 2007 and onwards. PPTX files are based on the Office Open XML format, which is an open and XML-based file format. PPTX files are more compact, and they are less prone to issues like macro-related security risks compared to PPT files.
