Bulgarian National Radio (Bulgarian: Българско национално радио, Bŭlgarsko natsionalno radio; abbreviated to БНР, BNR) is Bulgaria's national radio broadcasting organization. It operates two national and seven regional channels, as well as an international service – Radio Bulgaria – which broadcasts in 11 languages.
On 26 May 2008 RPTS of Kostinbrod in Bulgaria started the country's first regular broadcasts in digital format, using Digital Radio Mondiale (DRM). This signal is also used as the audio channel accompanying BNT's testcard.
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 nationalizing Rodno radio and making all broadcasting in Bulgaria a state-organized 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.
Public service broadcasting in Bulgaria, including BNR, is financed mainly through a state subsidy. The subsidy has to be spent on the preparation, creation and the transmission of the national and regional programmes. Its volume is determined annually on the basis of the average programme production costs per hour approved by the Council of Ministers, regardless of the programme type.
