The iPod nano is a portable media player with a video camera designed and marketed by Apple. The first generation of the iPod nano was introduced in 2005.[1] It uses flash memory, like the iPod Shuffle, but with a 2.2 inch (diagonal) QVGA display and the "click wheel" found on the iPod Classic. The iPod nano has gone through five models, or generations, since its introduction. The fifth generation (current) supports video recording, a microphone for voice memos, and a slightly larger screen than that of the previous generation.
