Järvi became Music Director of the New Jersey Symphony Orchestra (NJSO) in 2005, with an initial three-year contract. With the 2007 decision by the NJSO to sell its "Golden Age" collection of string instruments, there was press speculation as to whether Järvi would renew his contract with the NJSO, as he stated that their acquisition of this collection was an important factor in his decision to accept the music directorship. When asked about the possibility of leaving after 2008, he stated: "It's very possible, but I haven't thought about it yet." In October 2007, the NJSO announced that Järvi had extended his contract as music director through the 2008–2009 season. In February 2008, the orchestra announced the conclusion of Järvi's tenure as the NJSO's music director at the end of the 2008–2009 season. In March 2009, the NJSO announced that Järvi had agreed to serve as the orchestra's artistic adviser, and named him their conductor laureate, after the scheduled conclusion of his contract as music director.
