iTunes is a media player by Apple.
The iTunes software allows users to purchase, download, and manage music, videos, applications, and other media.
Released in 2001, the software originally provided a media player as a way for Macintosh users to manage their digital music collections and sync them to a device, the iPod.
In 2003 Apple added the ability to buy music from the iTunes store, which the company released for Windows in the same year.
This move helped to create the widespread adoption of iPods.
