SoundJam MP, developed by Bill Kincaid and released by Casady & Greene in 1999, was renamed iTunes when Apple purchased it in 2000. Robbin, Kincaid, and Dave Heller moved to Apple as part of the acquisition, where they continue to work today as the software’s original developers. They simplified SoundJam’s user interface, added the ability to burn CDs, and removed its recording feature and skin support. On January 9, 2001, iTunes 1.0 was released at Macworld San Francisco. Macintosh users immediately began poking through iTunes’s resource fork, where they discovered numerous strings and other resources that indicated iTunes was a re-engineered SoundJam MP. Casady & Greene ceased distribution of SoundJam MP on June 1, 2001 at the request of the developers.
A version of iTunes was shipped with cell phones from Motorola, which included the ability to sync music from an iTunes library to the cellphone, as well as a similar interface between both platforms. Since the release of the iPhone, Apple has stopped distributing iTunes with other manufacturers’ phones. In the absence of support from Apple, Nokia has released a Mac application called Nokia Multimedia Transfer that supports transferring data from iTunes and iPhoto onto some Nokia devices. Palm however reverse engineered iTunes to allow its Pre device to sync directly with iTunes. It did this by fooling iTunes into thinking the device was an iPod.
In late March 2010, Apple released version 9.1, which has support for the iPad and its iBooks application.
In late June 2010, Apple released version 9.2, which brought support for the new iPhone 4, as well as any iDevices running iOS 4, included support for the new iPhone and iPod Touch version of the iBooks app.
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.
