Boris III of Bulgaria
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.
