ETO: Laws against German Jews keep growing, this time banning them from owning wireless radios. They face harsh measures if caught with one, whether or not they are tuning in to BBC broadcasts from London.
German Jews are forbidden to own radios
Joseph Goebbels, head of the Ministry of Public Enlightenment and Propaganda, knew that radio was the most powerful and effective method of putting over any message the regime desired. The public had to leave home to go to the cinema while some simply did not read a newspaper. According to Goebbels, "What the press has been in the Nineteenth Century, radio will be for the Twentieth Century."
The problem for the Nazis was that radio could be an equally effective tool for the Allies. Therefore, measures would have to be taken to purge German radio of influence opposed to the Reich. In regard to the Jews, the easiest way to do that was to simply deny them possession of a radio with yet another law against German Jews.
By April 1941, Jews in all Nazi-occupied territory were ordered to forfeit all wireless radios, in an effort to deny them access to news from the Allies and Dutch government-in-exile broadcasts from London. Although death or deportation (which would likely lead to death) faced those that dared not comply, many took to concealing radio sets behind wall panels and such in order to listen to BBC broadcasts free of Nazi propaganda.
