Keynote (event)

The Apple Keynote event (also known as the "Stevenote" and Apple Event) is a presentation that Apple gives to the press, usually two to three times a year. Apple will typically announce new products and provide other updates about the company's business.

One more thing
At a typical "Stevenote", Steve Jobs would often begin to leave the stage after his main presentation, but then walk back and announce "one more thing". Examples of such surprise product announcements include: color iMacs in 1999, the iPod Shuffle in 2005, FaceTime for iPhone in 2010, and iTunes Match in 2011.

Trivia

 * Apple will tend to announce new software at WWDC and new hardware at other events.
 * The last keynote that Steve Jobs presented was on June 6, 2011, where he announced iCloud, OS X Lion, and iOS 5.
 * This role has largely been assumed by new CEO Tim Cook after Jobs' death. An example is the March 7th, 2012 keynote where Apple announced the iPad 3.
