The iPod is a line of portable media players and multi-purpose pocket computers designed and marketed by Apple Inc. The first line was released on October 23, 2001. The most recent iPod redesigns were announced on September 12, 2012. There are three current versions of the iPod: the ultra-compact iPod Shuffle, the compact iPod Nano and the touchscreen iPod Touch. Like other digital music players, iPods can serve as external data storage devices. The devices are controlled by the Samsung ARM and the Apple A5 CPUs. While the iPhone and iPad have essentially the same media player capabilities as the iPod line, they are generally treated as separate products. During the middle of 2010, iPhone sales overtook those of the iPod.
