Joseph Goebbels was elected the Minister of National Enlightenment and Propaganda. He controlled the press, radio, cinemas, theatres and art. Books by Jews and books disagreeing with Nazism were burnt.
Goebbels organised the production of cheap radios and installed loudspeakers on every street so everyone could hear Hitler's live speeches at all times.
Nazis held party rallies in Nuremberg every year. They had a different theme every time.
Leni Riefenstahl recorded the 1934 Nuremberg Rally of 'Unity and Strength' and made a film 'Triumph of the Will' promoting the cult.
