 Externally, the Reichssender Hamburg transmitted propaganda material to listeners overseas – in particular to those living in the British Isles – and, during World War II, broadcast regular programming aimed at sapping the morale of the civilian population of the United Kingdom.Its most famous wartime broadcaster in English was William Joyce (popularly known, from his accent and speaking-manner, as "Lord Haw-Haw").The Reichssender Hamburg was the last short-wave station to remain on the air in wartime Germany.
