London-Sire Records was an American-based record label owned by Warner Music Group, created in August 1999 with the merging of Warner Music Group's struggling Sire Records Group and the US division of London Recordings, which WMG had acquired from Universal Music Group following their merger with PolyGram in December 1998.[2][3] Seymour Stein remained at the helm as CEO, with Peter Koepke acting as co-head. However, the binding of the two companies proved to be largely unsuccessful, and failed to produce a hit. The label was shuttered by AOL Time Warner at the end of 2001,[1] and played a role in the dissolution of AOL Time Warner's partnership in April 2003. Sire was later relaunched by Stein as an imprint of Warner Bros. Records.[2]
