History
Prior to working together on SoundJam MP, Jeff Robbin and Bill Kincaid had worked for Apple in the 1990s as system software engineers assigned to the Copland operating system, a project that was abandoned before completion. After the Copland project's cancellation, Robbin and Kincaid left Apple. Robbin went on to create Conflict Catcher, a classic Mac OS utility, and Kincaid worked at a startup.

Kincaid created Mac-compatible hardware and device driver support for the  line of digital audio players. He then enlisted Robbin to develop the front-end for the MP3-player software they named SoundJam MP. Dave Heller later joined them, completing the core team. The development team chose Casady & Greene to publish SoundJam MP because the company had previously published Robbin's Conflict Catcher. David Pogue wrote SoundJam MP's documentation. SoundJam MP quickly became a successful product in the Mac music player market, competing with Panic's Audion, released only a month apart.

Acquisition
In early 2000, Apple wanted to purchase MP3 player software for use with Apple's desktop computers. Apple sought meetings with both Panic and Casady & Greene. Caught up in negotiations with AOL, Panic was not able to set up a meeting with Apple. Turning instead to Casady & Greene, Apple purchased the rights to the SoundJam MP software in a deal covered by a two-year secrecy clause. Working as employees of Apple, Robbin, Kincaid and Heller continued to develop the software which would become iTunes. All three continue to work at Apple; Robbin is the lead developer of iTunes.

On January 9, 2001, Apple debuted iTunes 1.0 to the public. Curious Macintosh users immediately began poking through iTunes' resource fork, where they discovered numerous strings and other resources that indicated iTunes was a re-engineered SoundJam MP. After a request from Robbin and Kincaid, Casady & Greene ceased distribution of SoundJam MP on June 1, 2001.
