History
1999: Seagram buyout of PolyGram and unit formation
On December 10, 1998, the Seagram Company acquired PolyGram for $10.6 billion and merged its music label unit with that of MCA Music, forming Universal Music Group.
In 1999, following the formation of Universal Music Group, 14 recording labels, including Island Records, Def Jam Recordings, and Mercury Records, merged to form Island Def Jam Music Group. Although Island Def Jam Music Group consolidated the labels, they continued to operate as separate, autonomous labels. Lyor Cohen was named the unit’s president.
Island Def Jam Music Group was one of four newly established Universal Music label groups, along with the Universal Motown Republic Group, Verve Label Group, and Interscope Geffen A&M Records.
In the United Kingdom, Island Records operated under Universal’s Island Records Group, while Def Jam UK was established and distributed by Mercury, which also managed its artists under the same banner.
