Beginning in the late 1920s, a distinctive style first called "old-timey" or "hillbilly" music began to be broadcast and recorded in the rural South and Midwest; early artists included the Carter Family, Charlie Poole and his North Carolina Ramblers, and Jimmie Rodgers. The performance and dissemination of this music was regional at first, but the population shifts caused by World War II spread it more widely. After the war, there was increased interest in specialty styles, including what had been known as "race" and "hillbilly" music; these styles were renamed to "rhythm and blues" and "country and western", respectively. Major labels had some success promoting two kinds of country acts: Southern novelty performers like Tex Williams and singers like Frankie Laine, who mixed pop and country in a conventionally sentimental style. This period also saw the rise of Hank Williams, a white country singer who had learned the blues from a black street musician named Tee-Tot, in northwest Alabama. Before his death in 1953, Hank Williams recorded eleven singles that sold at least a million copies each and pioneered the Nashville sound.
