Marketing maverick Steve Stoute tells Lydia Moynihan how a pair of Ray-Bans changed his life—and the way brands tap culture. The music exec-turned-ad king spills on selling 10 million "Men in Black" soundtracks, only to watch Will Smith’s shades outsell them by a mile. Now, he's flipping the script with UnitedMasters, helping artists own their music while schooling legacy brands on how not to get left behind. #stevestoute #marketing #tech
