Hardware
The iPod is a line of portable media players and multi-purpose pocket computers designed and marketed by Apple Inc. The first version was released on October 23, 2001, about ​ 8 1 ⁄ 2 months after the Macintosh version of iTunes was released. As of May 28, 2019, only the iPod Touch (7th generation) remains in production. Like other digital music players, some versions of the iPod can serve as external data storage devices . Prior to macOS 10.15, Apple's iTunes software (and other alternative software) could be used to transfer music, photos, videos, games , contact information, e-mail settings, Web bookmarks, and calendars to the devices supporting these features from computers using certain versions of Apple macOS and Microsoft Windows operating systems. Before the release of iOS 5, the iPod branding was used for the media player included with the iPhone and iPad , a combination of the Music and Videos apps on the iPod Touch. As of iOS 5, separate apps named Music and Videos are standardized across all iOS-powered products. 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.
