Time Warner sold its 50 percent stake in Interscope back to Field and Iovine for $115 million in September 1995 due to controversy over gangsta rap and explicit lyrics.

Bennett, and other public figures had accused the label of releasing music that glorified violence, putting pressure on Time Warner to distance itself from Interscope.
Interscope negotiated a $10 million deal with Dr. Dre and Marion "Suge" Knight in 1992 to finance and distribute Death Row Records.
