Then in 2001, the major label Universal Music (then a division of Vivendi Universal) bought eMusic.com for USD 24.6 million. In November 2003, the service was purchased from VU Net USA by a New York-based Private Equity arm of JDS Capital Management, Inc. Following a contentious period during which information disseminated by the company was limited, it was relaunched in 2004. Relaunch was soon followed by a new format for the eMusic site, significant increase in both editorial and music content and an eventual price increase for most subscription levels.
