iTunes was developed from SoundJam MP by Mac software firm Casady & Greene. Apple bought the copyright for SoundJam MP and hired three programmers who created SoundJam, Bill Kinkade, Jeff Robin, and Dave Heller. The first release of iTunes is quite alike to SoundJam MP, adding CD burning capabilities and a better user interface. Apple later added a number of major features to subsequent versions of iTunes.





The music player has evolved over time: from the ability to view iTunes music library to the ability to play video in various formats, from the introduction of iTunes store to the addition of Podcast, as well as the launch of iTunes on other operating systems and the release of Apple Music, it has truly revolutionized the way people listening to music and entertaining the digital goods.





Today, iTunes enables users to manage media content, create playlists, synchronize media content with iOS devices including the iPhone and iPad, streaming Internet radio, purchase music, films, television shows, audiobooks and applications via the iTunes Store. Voices from many people, however, suggests that iTunes should be replaced by other Service, as AirPlay 2 already available on third-party devices.
