Ipods are 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. The random-play capability of the iPod shuffle is reflected in its name. Like many digital audio players, iPods can also serve as external data storage devices. Apple focused its development on the iPod's unique user interface and its ease of use, rather than on technical capability.

As of October 2005, the lineup consists of the video-capable fifth generation iPod; the smaller iPod nano; and the display-less iPod shuffle. These models were updated in September 2006.

The bundled software used for transferring music is called iTunes. As a jukebox application, iTunes stores a comprehensive library of music on the user's computer and can play, burn, and rip music from a CD. It can also sync photos and videos.

The iPod is currently the world's best-selling range of digital audio players and its worldwide mainstream adoption makes it one of the most popular consumer brands, to the point that the name “iPod” has become a generic term for any .mp3 player. Some of Apple's design choices and proprietary actions have, however, led to criticism and legal battles.
