iTunes is Apple's media player used for music, audiobooks, podcasts, and recently added music videos, television shows, and movies. Built on the QuickTime foundation, iTunes is compatible with all QuickTime encoded media.

As of October 2005, iTunes has captured more than 80% market share of digital audio players in markets supported on both the Mac OS and Windows platforms.

The iTunes Store (originally the iTunes Music Store) was launched and integrated into version 4.0 of iTunes in April of 2003, enabling customers both on Mac and Windows platforms to purchase audio files, encrypted with Apple's Fairplay technology, over the internet for individual use. The release of the iTunes Music Store delivered a more reasonable solution to obtaining digital audio files legally over the internet.
