iPod is a brand of portable media players designed and marketed by Apple and launched in October 2001. The line-up currently consists of the original style hard drive-based flagship iPod classic, the premium iPhone-like iPod touch, the mid-level video-capable iPod nano, and the low-end screenless iPod shuffle. Former products include the compact iPod mini (replaced by the iPod nano) and the high-end spin-off iPod photo (re-integrated into the main iPod classic line). The current iPod classic models store media on an internal hard drive, while all other current models use flash memory to enable their smaller size. Like many digital music players, iPods can also serve as external data storage devices.
