Dragnet, “Big Rod,” aired on March 3, 1954.
Dragnet was created and produced by Jack Webb, who also starred as Sergeant Joe Friday. His goal was to create a show that was realistic, so he attended police academy classes and did ride-alongs with the Los Angeles Police Department as part of his research. The cases in the shows were based on actual cases handled by the LAPD. Dragnet was broadcast on NBC radio stations from 1949 to 1957. It overlapped with it’s TV version which ran from 1951 to 1959 in black and white, and was brought back to TV in color from 1967 to 1970.
