Until the release of iOS 5 in 2011, all iPhones, iPod Touches and iPads required iTunes for activation and updating mobile apps. Starting in 2005, Apple expanded on the core music features with support for digital video, podcasts, e-books, and mobile apps purchased from the iOS App Store. 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. Developed by Apple Inc., 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 software program that acts as a media player, media library, mobile device management utility, and the client app for the iTunes Store.
