History Listening to radio broadcasts from other countries having become popular in Bulgaria by the late 1920s, a group of engineers and intellectuals founded Rodno radio ("Native, or homeland, radio") on 30 March 1930 with the aim of providing Sofia with its own radio station. Broadcasting began in June the same year. On 25 January 1935, Boris III of Bulgaria signed a decree nationalising Rodno radio and making all broadcasting in Bulgaria a state-organised activity. In early 1936, a new and more powerful medium-wave transmitter sited near Sofia was joined by additional transmitting stations at Stara Zagora and Varna, giving Bulgarian National Radio countrywide coverage, and on 21 May of that year Radio Sofia began broadcasting internationally. On 1 January 1993 BNR was admitted to full active membership of the European Broadcasting Union (EBU)
