"The Aqua GUI made its debut in Mac OS X's Developer Preview 3 ("DP3"), demonstrated at the February 2000 MacWorld Expo in Tokyo. Aqua's first appearance in a commercial product was in iMovie 2, in which the buttons and the scroll bar acquired the Mac OS X Aqua look. It next proceeded to the Mac OS X Public Beta in autumn of 2000 before ending up in iTunes in January 2001."
