iPod is a brand of portable digital media player designed and marketed by Apple Computer. Devices in the iPod family provide a simple user interface designed around a central scroll wheel (with the exception of the iPod shuffle). Most iPod models store media on a built-in hard drive, while the smaller iPod shuffle and iPod nano use flash memory. Like most digital audio players, an iPod can serve as an external data storage device when connected to a computer.

As of January 2006, the lineup consists of the fifth-generation iPod which can play videos, the iPod nano which has a color screen, and the iPod shuffle; all three iterations were released in 2005. The iPod is currently the world's best-selling digital audio player.
