iTunes is a digital media player software, which can be used for organizing and playing digital video and music files. iTunes is also an interface which helps manage the contents on Apple's iPod and other digital media players such as the iPad and iPhone. Also, iTunes can be connected to the iTunes Store through the Internet to download and buy music videos, music, applications, television shows, audiobooks, iPod games, podcasts, movie rentals and feature length films, and ringtones (can only be used for the iPhone). It can also be used to download apps for the iPod and iPhone.
iTunes was first introduced by Apple Inc. on the 9th of January, 2001, in San Francisco. At Apple's "Rock and Roll" keynote in September 2009, iTunes 9 was introduced. The latest version of iTunes is 9.1, which also supports the iPad.
iTunes is a software that permits the user to manage video and audio files on a personal computer. Officially, iTunes is needed to manage the audio files of an iPod, although an alternative software does exist. One may organize one’s music into playlists contained in one or more libraries, record CDs, copy files to any digital audio player, buy videos and music via its inbuilt music store, support songs onto a DVD or CD and encode the music into numerous audio formats. Also, one may add PDF files to one’s library, but it is impossible to move the PDFs to an iPhone or iPod.
iTunes may be downloaded free of cost for Windows Vista, Mac OS X v10.4+, Windows XP, and Windows 7 from Apple's website. It is also complimentary with all Macs, and some of the Dell and HP computers. Earlier versions are made available for Mac OS X v10.0-10.3, Mac OS 9 and Windows 2000.
