Apple Events

Keynotes are presentations Apple Inc. gives to announce new products or services to the world. Recently, they have been in March, June or July, and September for iPad announcements, WWDC (for iOS, and formerly iPad, announcements), and a Special Event (iPad or iPod touch announcements) respectively. They were sometimes called Stevenotes as Steve Jobs was the person who presented the announcements. That name has since dissipated because of his passing.
