==History==
Keynote was first announced on January 7, 2003 by Steve Jobs at Macworld Expo in San Francisco. Jobs revealed that he had been preparing his keynote event presentations with Keynote, stating that "Using Keynote is like having a professional graphics department to create your slides." Keynote took advantage of Mac OS X graphics technologies, such as Quartz, QuickTime, and OpenGL to create presentations with anti-aliased text, dynamic effects, and cinematic transitions. It became available to the public that day for 99.Apple Unveils Keynote, Apple Computer. 2003-01-07.
