History
German physicist and inventor Manfred von Ardenne gave a public demonstration of a television system using a cathode ray tube for both transmission (using flying-spot image scans, not a camera) and reception, at the 1931 show.
In 1933 The Volksempfänger (VE 301 W), a Nazi-sponsored radio receiver design, was introduced. Ordered by Dr. Joseph Goebbels, designed by Otto Griessing, sold by Gustav Seibt, it was presented at the tenth Berliner Funkausstellung on 18 August 1933 , its price fixed at 76 Reichsmark (RM). 100,000 units were sold during the exhibition. The importance of radio as a mass medium for the dissemination of propaganda and entertainment throughout Germany had long been clear to Goebbels. In 1938 the DKE 38 (Deutscher Kleinempfänger 38, i.e. German miniature receiver 1938) followed, the price fixed at 35 RM.
