Newer iOS devices have less reliance on iTunes in order to function, though it can still be used to back up the contents of mobile devices, as well as to share files with personal computers. Until the release of iOS 5 in 2011, all iPhones, iPod Touches and iPads required iTunes for activation and updating mobile apps. In 2005, however, Apple expanded on the core features with support for digital video, podcasts, e-books, and mobile apps purchased from the iOS App Store (the last of which it discontinued in 2017). Originally announced by CEO Steve Jobs on January 9, 2001, iTunes' original and main focus was music, with a library offering organization, collection, and storage of users' music collections. Options for sound optimizations exist, as well as ways to wirelessly share the iTunes library. It is used to purchase, play, download, and organize digital multimedia, on personal computers running the macOS and Windows operating systems, and can be used to rip songs from CDs, as well as play content with the use of dynamic, smart playlists.
ITunes ( / ˈ aɪ t( j) uː n z/) is a media player, media library, Internet radio broadcaster, mobile device management utility, and the client app for the iTunes Store, developed by Apple Inc.
