 Featuring three group members who were marketed for their individual personalities (a move unprecedented at the time) and Diana Ross's pop-friendly voice, the Supremes broke down racial barriers with rock and roll songs underpinned by R&B stylings.The group became extremely popular both domestically and abroad, becoming one of the first black musical acts to appear regularly on television programs such as "Hullabaloo", "The Hollywood Palace", "The Della Reese Show", and, most notably, "The Ed Sullivan Show", on which they made 17 appearances.The Supremes' cross-cultural success effectively paved the way for the mainstream success of contemporaneous label mates such as the Temptations, the Four Tops and the Jackson 5.
