Dragnet follows Los Angeles Police Sergeant Joe Friday, played by series creator Jack Webb, as he works real-case-inspired investigations with the clipped, just-the-facts narration that became instantly iconic. Airing from 1949 to 1957, it's often credited as the show that invented the police procedural, prized for its stark sound design, terse dialogue, and documentary-style realism. Friday's partner changed more than once over the run—Barton Yarborough's Sgt. Ben Romero held the role in the early years until his sudden death, after which Ben Alexander's Officer Frank Smith took over for most of the seasons that followed. For modern listeners, it's a fascinating listen back to the show that set the template for every cop drama since.
