Gang Busters was an American dramatic radio program heralded as "the only national program that brings you authentic police case histories." It premiered as G-Men, sponsored by Chevrolet, on July 20, 1935. After the title was changed to Gang Busters January 15, 1936, the show had a 21-year run through November 20, 1957. Beginning with a barrage of loud sound effects â guns firing and tires squealing â this intrusive introduction led to the popular catch phrase "came on like Gang Busters."The series dramatized FBI cases, which producer-director Phillips H. Lord arranged in close association with Bureau director J. Edgar Hoover. Hoover insisted that only closed cases would be used.
