The iPod nano has seen quite a few aesthetic and feature changes since it first launched in 2005. It began with a simple rectangular design with clickwheel controls and a small color screen, then evolved into a square-like shape with video support with the 3rd generation in 2007, and returned to its rectangular roots with the 4th generation in 2008, and finally the addition of a built-in camera with video recording in 2009. Now Apple has taken a drastic new approach with the 2010 iPod nano, which for the first time ditches the traditional clickwheel in exchange for a multitouch display and trims the size and shape of the device down substantially.
in 2005, Cupertino adopted a "special assignment" to help the US Department of Energy in developing a top-secret iPod which had a special but hidden function.
Released in late 2001, about eight months after the arrival of iTunes, the original Apple iPod music player featured a mini version of the game Breakout.
