Radio broadcasting was the cheapest form of entertainment, and it provided the public with far better entertainment than most people were accustomed to. As a result, its popularity grew rapidly in the late 1920s and early 1930s, and by 1934, 60 percent of the nation's households had radios.

Chandu, the Magician

Chandu the Magician is an American supernatural radio drama which originally aired from 1931–1936. A revival on a different network took place 12 years later, airing from 1948–1950. The series was created by Harry A. Earnshaw (1878–1953) and Raymond R. Morgan. The two series starred Frank Chandler, also known as Chandu, an American who had learned mystical arts, such as astral projection, which he used to fight criminals and villains, including the evil Baron Roxor.
