National Barn Dance, broadcast by WLS-AM in Chicago, Illinois starting in 1924, was one of the first American country music radio
programs and a direct precursor of the Grand Ole Opry. National Barn Dance also set the stage for other similar programs, in part because the clear-channel signal
of WLS could be received throughout most of the Midwest and even beyond in the late evening and nighttime hours, making much of the United States (and Canada) a
potential audience. The program was well received and thus widely imitated. National Barn Dance ended its broadcast in 1968.
