Related to iTunes: ITunes Store
iTunesSoftware for Mac and Windows from Apple that is widely used to organize media on the computer as well as on iPods, iPhones and iPads. Introduced in 2001 for Mac and two years later for Windows, due to the sheer number of PCs, more people use iTunes on Windows than they do on Macs. Apple's iTunes Store is also integrated for purchasing media, and a user's existing media collection can be added to the iTunes library as well. iTunes lets users rip CDs to the computer as well as burn CDs with content in their music library, and it also keeps the Apple device's firmware up-to-date.
Apple copy protects TV shows and movies sold on the iTunes Store, and it previously protected its music. Therefore, certain restrictions apply (for details, see FairPlay).
When Home Sharing in iTunes is turned on, users can stream their content to their Apple TV boxes for home theater viewing. Playlists can also be opened to other iTunes users on the network, and titles can be streamed from one computer to another. Originally a "share-but-not-save" feature, in 2009, Home Sharing in iTunes 9 finally enabled users to copy files across the network, not just play them. See iPod, iTunes Match, iTunes U, media player and playlist.
