The iPod is a brand of portable media players designed and marketed by Apple Computer. Devices in the iPod family are designed around a central scroll wheel (except for the iPod shuffle, which uses click buttons) and 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 2006, the lineup consists of the 5th generation iPod that plays videos; the smaller, second generation iPod nano; and the display-less iPod shuffle. These models were updated in 2006.

The bundled software used for transferring music, photos and videos 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. The most recent versions have photo and video synchronization features. These features open up the possibility of playing back standard definition quality television and movies from the iPod onto a television set. In addition to the iTunes Store others sources of legal television content prepared for iPods include Google Video. Many of these services work only in the US, including iTunes.

The iPod is currently the world's best-selling digital audio player and its worldwide mainstream adoption makes it one of the most popular consumer brands. Some of Apple's design choices and proprietary actions have, however, led to criticism and legal battles.
