 The synthesis of music styles that evolved into what is now called rhythm and blues, previously labeled "race music" by the record companies, found a broad youth audience in the postwar years and helped to catalyze changes in racial relations in American society.By 1948, RCA Victor was marketing black music under the name "Blues and Rhythm".In 1949, Jerry Wexler, a reporter for "Billboard" magazine, reversed the words and coined the name “Rhythm and Blues” to replace the term “Race Music" for the magazine’s black music chart.
