Deutschlandradio (DLR or DRadio) is a national German public radio broadcaster. It operates four national networks: Deutschlandfunk: mainly news and information, Deutschlandfunk Kultur: culture in a broader sense, Deutschlandfunk Nova: aimed at young adults, mainly spoken-word, Dokumente und Debatten: opt-out channel, often for special event. Deutschlandfunk was originally a West German news radio targeting listeners within West Germany as well as in neighbouring countries, East Germany and the rest of the communist block, whereas Deutschlandradio Kultur is the result of a merger of West Berlin's RIAS station and East Berlin's DS Kultur after German reunification.
