Deutschlandradio, with a 40% share, is the largest of the ROC’s four shareholders. It was born on the same day: 1 January 1994. As the ROC’s majority shareholder, Deutschlandradio can draw on the programmes of four ensembles for its stations. Deutschlandfunk Kultur and Deutschlandfunk work together closely with the ROC’s two orchestras and two choirs, recording about 60 concerts a year that are broadcast live or pre-recorded.

Both of the broadcasters are also available as long-term production partners for CD recordings, often recording unknown repertoire by composers whose works have been unjustly forgotten or suppressed.
