Description Launched in 1990, Microsoft Powerpoint is the most popular presentation application in the world. Released as part of the Microsoft Office software package, the application is the de facto standard for presentations. Allowing the user to create dynamic, animated slides, the tool is intuitive and allows for text, images and graphics to be added. The tool benefits from being consistent with Word and Excel in terms of layout and toolbars. The tool also allows the user to incorporate Visual Basic code so that user defined macros can be implemented to allow for non-linear slide transitions. Microsoft have reported that Powerpoint has been installed on over 1 billion computers, emphasising its huge market dominance.

Technical Details PPT is a binary file format that was used by all Microsoft Powerpoint releases between 1997 - 2003. This has been superseded by Microsoft's open source XML based file formats initially released with Office 2007. The latest version of Microsoft Powerpoint, Powerpoint 2010, allows the user to undertake advanced editing such as embedding video within slides. The XML based file format results in a more efficiently compressed file, thus saving the user storage space.

Description Files with a .key extension are created by Apple's "Keynote" application which forms part of Apple's iWork office suite, a set of applications which run on the Mac OS X and iOS operating systems, and also includes Numbers (for spreadsheets) and Pages (for word processing).

Keynote began life in 2002 as an internal Apple tool developed for Steve Jobs to help him present at MacWorld. The first version was made available to the public in 2003 as Keynote 1.0 and was designed to compete with Microsoft's Powerpoint presentation software which formed part of Microsoft Office.

Designed to let users easily create, play and share presentations, Keynote contains most of the features found in modern presentation software, such as a slide navigator, the ability to add tables, shapes and charts to slides and a powerful media browser which allows users to drag and drop music from from iTunes, and photos from iPhoto and Aperture into their slides.

Keynote contains a large number of pre-designed themes to let users select common presentation formats, and powerful graphics tools to manipulate embedded images and provide advanced 3D transitions between slides (powered by OpenGL). The major Keynote releases are summarised below:

Technical Details Official file format specifications for iWork Keynote files are not published by Apple, but it is still possible to look at a developer document Apple released for iWork '05 file formats.

A .key file is actually a compressed ZIP file comprised of a number of other different files combined that together make up a .key file. The most recent version of Keynote saves files with an "Index" directory containing Apple's proprietary IWA file format, a "Metadata" directory with .plist files, a "Data" directory with image assets (e.g. backgrounds and photos used in slides) and one or more jpg files for allowing quick previews.

Files created by Keynote in iWork cannot be opened by programs other than iWork.
