Gang Busters was a famous radio program that was first heard in 1936 and aired until 1957. Its creator, Phillips H. Lord, worked with J. Edgar Hoover to bring closed FBI cases to the listening public. All scripts were based on actual police records and had to be okayed by the Bureau first.
The radio show was originally titled G-men. It began on July 20, 1935 under the sponsorship of Chevrolet. The name was changed to Gang Busters on January 15, 1936. Palmolive Soap was the new sponsor for the Wednesday night CBS show.
The sound effects of police sirens, Tommy guns, and screeching tires that opened the show were dramatic. They inspired the expression "coming on like Gang Busters".
