Rhythm and blues, often abbreviated to R&B and RnB, is a genre of popular African-American music that originated in the 1940s. The term was originally used by record companies to describe recordings marketed predominantly to urban African Americans, at a time when 'urbane, rocking, jazz based music with a heavy, insistent beat' was becoming more popular. The term has subsequently had a number of shifts in meaning. In the early 1950s, the term rhythm and blues was frequently applied to blues records. Starting in the mid-1950s, after this style of music contributed to the development of rock and roll, the term 'R&B' became used to refer to music styles that developed from and incorporated electric blues, as well as gospel and soul music. By the 1970s, rhythm and blues 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'.
