Dragnet ran from June 3rd,1949 to February 26th,1957 on NBC at various times and days and starred Jack Webb as Detective Sergeant Joe Friday. Various partners throughout the show's run were Sergeant Ben Romero (Barton Yarborough), Ed Jacobs (Barney Phillips), and Officer Frank Smith (Ben Alexander).
Webb was the creator/Director of the series and wanted everything to be as authentic as possible, down to the last sound effect. The stories were based on actual police files and "the names were changed to protect the innocent".
Dragnet broke a few radio taboos as well, such as dramatizing sex crimes. Children also were killed on occasion as in the episode "Twenty-Two Rifle For Christmas". The series eventually went to television and ran there for many years.
The Big Trial: Joe Friday and Ben Romero search for a hit and run driver. Originally aired April 20th, 1950.
