The iTunes version history begins in 1998 and continues to the present. Initially conceived as a simple music player, over time iTunes developed into a sophisticated multimedia content manager, hardware synchronization manager and e-commerce platform. The current version of iTunes enables users to manage media content, create playlists, synchronize media content with handheld devices including the iPod, iPhone and iPad, re-image and update handheld devices, stream Internet radio and purchase music, films, television shows, audiobooks and applications via the iTunes Store.
Apple based the initial release of iTunes on SoundJam MP, a program developed by Bill Kincaid and released by Casady & Greene in 1999. Apple purchased the program from Casady & Greene in 2000. At the time of the purchase, Kincaid, Jeff Robbin and Dave Heller left Casady & Greene to continue development of the program as Apple employees. At Apple, the developers simplified SoundJam's user interface, added the ability to burn CDs, and removed the program's recording feature and skin support.
Apple released version 1.0 of the program under a new name, "iTunes", on January 9, 2001, at Macworld San Francisco. Macintosh users immediately began poking through iTunes's resource fork, where they discovered numerous strings and other resources that indicated that iTunes was a re-engineered Sound Jam MP. Casady & Greene ceased distribution of SoundJam MP on June 1, 2001 at the request of the developers.
Originally a Mac OS 9-only application, iTunes began to support Mac OS X with the release of version 2.0 in October, 2001. Release 2.0 also added support for a then-new product, the iPod. Version 3 dropped Mac OS 9 support but added smart playlists and a ratings system. In April 2003, version 4.0 introduced the iTunes Store; in October, version 4.1 added support for MicrosoftWindows 2000 and Windows XP. Introduced at Macworld 2005 with the new iPod Shuffle, Version 4.7.1 introduced the ability to convert higher-bitrate songs to 128kbit/s AAC automatically, as these devices did not natively support audio encoded in AIFF or Apple Lossless formats, also improving the value proposition of the Shuffle's limited flash-only storage. Version 7.0 introduced gapless playback and Cover Flow in September 2006. In March 2007, iTunes 7.1 added support for Windows Vista, and 7.3.2 was the last Windows 2000 version.
iTunes lacked support for 64-bit versions of Windows until the 7.6 update on January 16, 2008. iTunes is currently supported under any 64-bit version of Windows, although the iTunes executable is still 32-bit. The 64-bit versions of Windows XP and Windows Server 2003 are not supported by Apple, but a workaround has been devised for both operating systems. Version 8.0 added Genius playlists, grid view, and a new default visualizer.
On September 1, 2010, Apple held their annual music press event where they unveiled an updated version: iTunes 10. The new version was available for download later that day. One major feature includes the integration of "iTunes Ping", which brings a social factor to the iTunes experience. Apple CEO Steve Jobs also announced a new logo, one without a CD in the background because of the increasing popularity of iTunes digital downloads.
In October 2012, Apple announced the launch of the iPhone 5 and iPad Mini, the refresh of the iPod and Mac lines, and the upcoming release of iTunes 11. Slated for release by the end of October, the launch was pushed back to November 29, 2012. This version included tighter integration with iCloud, and a new user interface. Users' libraries now include all media they have stored in their iCloud account, along with any media unique to the device they are using. Media stored in the cloud don't need to be downloaded before playing, allowing a larger collection to be accessible without increased disk usage. The new user interface includes a refreshed grid view, which replaces Cover Flow as the default layout method. With this change, Cover Flow is no longer available within the application. With the release of this software, the iTunes Store was redesigned to remain consistent with the new interface, and the stores available on iOS devices. The social element Ping was also removed and replaced by increased Twitter and Facebook integration. Other minor changes included disabling the sidebar by default, and slightly altering the icon to match that of the Mac App Store better.
