Keynote is a presentation software application developed as a part of the iWork productivity suite (which also includes Pages and Numbers) by Apple Inc. Released in August 2007, the latest version, Keynote 4, runs on Mac OS X 10.4 Tiger and 10.5 Leopard only.
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.
In the fall of 2007, Apple released Keynote 4.0 in iWork 08, along with Pages 3.0 and the new Numbers 1.0 spreadsheet application.
Lawrence Lessig and Aaron Swartz frequently use Keynote for pitching using a technique referred to as "slides as chorus" or the Lessig Method. The presenter speaks fluently and never refers to the slides or reads from them. Each slide contains either a simple graphic or a very short string of text, sometimes a single word. While speaking, the slides are advanced in sync with what is being said, so there can be several slides displayed per sentence.
