PowerPoint 1.0 was released in 1987 and was originally only available for the Apple Macintosh, and only in black-and-white. It generated text-and-graphics pages that a photocopier could turn into overhead transparencies.
Later in1987, PowerPoint was purchased by Microsoft Corporation for a price of $14 million. The following year saw the first Windows and DOS version. It has since been a standard part of Microsoft’s Office suite of tools. The widespread use of PowerPoint for presentation has given rise to a trend in some business circles for increasingly elaborate presentations, with extensive use of artwork, animations, and even multimedia.
