Keynote is a presentation software application developed as a part of the iWork productivity suite by Apple Inc. Keynote 5 was announced on January 6, 2009 and is the most recent version. It adds new themes, transitions and animations, and the ability to control the slideshow with an iPhone or iPod touch through the Keynote Remote application which is available for purchase on the iTunes Store.
Keynote began as a software program for Apple CEO Steve Jobs to use in creating the presentations for Macworld Conference and Expo and other Apple keynote events. The program was first sold publicly as Keynote 1.0 in 2003, competing against existing presentation software, most notably Microsoft PowerPoint. In addition, Keynote includes truly three-dimensional transitions, such as a rotating cube or a simple flip of the slide.
In 2005 Apple began selling Keynote 2.0 in conjunction with Pages, a new word processing and page layout application, in a software package called iWork. At the Macworld Conference & Expo 2006, Apple released iWork '06 with updated versions of Keynote 3.0 and Pages 2.0. In addition to official HD compatibility, Keynote 3 added new features, including group scaling, 3D charts, multi-column text boxes, auto bullets in any text field, image adjustments, and free form masking tools.
