In the 2016 British TV series The Durrells which is based on a true story, the British family moves to the Greek island of Corfu.
In the last episode just months before the start of World War II a Greek police officer enters their home and tells them he has heard reports of they possessing a radio, and he is there to seize it. Which they deny.
I searched in the internet, but didn't find any historical information about the matter.
Was possession of a radio forbidden in 1930s Greece?
