Deutschlandradio (DLR or DRadio) is a national German public radio broadcaster. It operates four national networks:
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 Deutschlandfunk Kultur is the result of a merger of West Berlin's RIAS station and East Berlin's DS Kultur after German reunification. Both networks that used to broadcast mainly on the AM bands have since spread throughout Germany, having been allocated many additional FM transmitters.
Dokumente und Debatten is a digital-only opt-out channel. It broadcasts coverage of the federal parliament, sports events, talk shows and shipping forecasts. Many of the talk shows are rebroadcasts of the audio portions of TV shows made by ARD, ZDF or Phoenix.  It uses digital frequencies of both Deutschlandfunk and Deutschlandfunk Kultur.
Deutschlandradio is based in Cologne, with some departments—including Deutschlandfunk Kultur—based in Berlin.
On May 1 2017, DRadio Wissen was renamed Deutschlandfunk Nova, Deutschlandradio Kultur was renamed Deutschlandfunk Kultur.
Deutschlandradio has a 40% share in Rundfunk Orchester und Chöre GmbH, a non-profit organisation which operates:
