Microsoft PowerPoint is a presentation program developed by Microsoft. It is part of the Microsoft Office suite, and runs on Microsoft Windows and Apple's Mac OS X computer operating systems. PowerPoint is widely used by business people, educators, students, and trainers and among the most prevalent forms of persuasive technology. Beginning with Microsoft Office 2003, Microsoft revised the branding to emphasize PowerPoint's place within the office suite, calling it Microsoft Office PowerPoint instead of just Microsoft PowerPoint. The current versions are Microsoft Office PowerPoint 2007 for Windows and 2008 for Mac.
[edit] HistoryThe first version of PowerPoint was initially developed on 14 August 1984 by Robert Gaskins and Dennis Austin of Forethought, Inc. of Sunnyvale, California. The original version of this program was created by Dennis Austin and Thomas Rudkin.[1] Originally designed for the Macintosh computer, the initial release was called "Presenter". In 1987, it was renamed to "PowerPoint" due to problems with trademarks, the idea for the name coming from Robert Gaskins.[2] In August of the same year, Forethought was bought by Microsoft for $14 million USD ($26.2 million in present-day terms[3]), and became Microsoft's Graphics Business Unit, which continued to further develop the software. For most users,[weasel words] one of the most obvious changes introduced with PowerPoint 2000 (and the rest of the Office 2000 suite) was a clipboard that could hold multiple objects at once. Another noticeable change was that the Office Assistant, whose frequent unsolicited appearance in PowerPoint 97 had annoyed many users, was changed to be less intrusive.[citation needed] See also: Microsoft Office 2000 [edit] OperationPowerPoint presentations consist of a number of individual pages or "slides". The "slide" analogy is a reference to the slide projector, a device that has become obsolete with the use of PowerPoint and other presentation software. Slides may contain text, graphics, movies, and other objects, which may be arranged freely on the slide. PowerPoint, however, facilitates the use of a consistent style in a presentation using a template or "Slide Master". The presentation can be printed, displayed live on a computer, or navigated through at the command of the presenter. For larger audiences the computer display is often projected using a video projector. Slides can also form the basis of webcasts. PowerPoint provides three types of movements:
[edit] Cultural impactSupporters and critics generally agree[4][5][6] that the ease of use of presentation software can save a lot of time for people who otherwise would have used other types of visual aid—hand-drawn or mechanically typeset slides, blackboards or whiteboards, or overhead projections. Ease of use also encourages those who otherwise would not have used visual aids, or would not have given a presentation at all, to make presentations. As PowerPoint's style, animation, and multimedia abilities have become little more sophisticated, and as the application has generally made it easier to produce presentations (even to the point of having an "AutoContent Wizard" (discontinued in PowerPoint 2007) suggesting a structure for a presentation), the difference in needs and desires of presenters and audiences has become more noticeable. The benefit of PowerPoint is continually debated.[7] Its use in classroom lectures has influenced investigations of PowerPoint’s effects on student performance in comparison to lectures based on overhead projectors, traditional lectures, and online lectures. Not only is it a useful tool for introductory lectures, but it is also has many functions that allow for review games, especially in the younger grades. There are no compelling results to prove or disprove that PowerPoint is more effective for learner retention than traditional presentation methods.[8] The effect on audiences of poor PowerPoint presentations has been described as PowerPoint hell. [edit] VersionsVersions for Microsoft Windows include:
Note: There is no PowerPoint version 5.0 or 6.0, because the Windows 95 version was launched with Word 7.0. All Office 95 products have OLE 2 capacity — moving data automatically from various programs — and PowerPoint 7.0 shows that it was contemporary with Word 7.0. Versions for the Mac OS include:
Note: There is no PowerPoint 5.0, 6.0 or 7.0 for Mac. There is no version 5.0 or 6.0 because the Windows 95 version was launched with Word 7. All of the Office 95 products have OLE 2 capacity — moving data automatically from various programs — and PowerPoint 7 shows that it was contemporary with Word 7. There was no version 7.0 made for Mac to coincide with either version 7.0 for Windows or PowerPoint 97[9][10]. [edit] File formats
The binary format specification has been available from Microsoft on request, but since February 2008 the .ppt format specification can be freely downloaded.[12] In Microsoft Office 2007 the binary file formats were replaced as the default format by the new XML based Office Open XML formats, which are published as an open standard. Nevertheless, they are not complete as there are binary blobs inside of the XML files, and several pieces of behaviour are not specified but refer to the observed behaviour of specific versions of Microsoft product.
