With Hugh Marlowe (below) in the title role, Ellery Queen was introduced in
The Adventures of Ellery Queen on CBS Radio on June 18, 1939. Between
1939-1948, the show was broadcast alternately on CBS, NBC and ABC. The
premise was that a mystery would be dramatized but then interrupted when a
panel of celebrities would attempt to solve the mystery. The Gulf Oil Company
was the first commercial sponsor of the show.
