This tangent of RnB is now known as British rhythm and blues. By the 1970s, the term rhythm and blues changed again and was used as a blanket term for soul and funk. In the 1980s, a newer style of R&B developed, becoming known as Contemporary R&B. It combines elements of rhythm and blues, soul, funk, pop, hip hop and dance. Popular R&B vocalists at the end of the 20th century included Michael Jackson, Prince, R. Kelly, Stevie Wonder, Whitney Houston, and Mariah Carey.
