Radio in Colombia started in the early 1920s when a group of radio amateurs and enthusiasts brought the first receivers to the country,[1] mostly in order to listen broadcasts from Europe and the United States. Broadcasting started in September 1929, with state-owned HJN, predecessor of Radiodifusora Nacional de Colombia, and privately run La Voz de Barranquilla (HKD).[2] [3]
As of 2011, Colombia has three major national radio networks: state-run Radiodifusora Nacional de Colombia and private networks Caracol Radio and RCN Radio, with hundreds of affiliates. These networks appeared in the 1940s.[4]
There are other national networks, including Cadena Super, Todelar, Organización Radial Olímpica, and Colmundo, among others.
