The iPod is a brand of portable media players designed and marketed by Apple Computer and launched in 2001. Devices in the iPod range are primarily music players, designed around a central scroll wheel (although the iPod shuffle has buttons only). The full-sized model stores media on an internal hard drive, while the smaller iPod nano and iPod shuffle use flash memory. Like many digital audio players, iPods can also serve as external data storage devices. Apple chose to focus its development on the iPod's simple user interface and its ease of use, rather than on technical capability.

As of October 2005, the lineup consists of the 5th generation iPod that plays videos; the smaller iPod nano; and the display-less iPod shuffle. These models were updated in September 2006.
