In the late 1940s, CBS chairman William S. Paley, a fan of the Philip Marlowe radio serial, asked his programming chief, Hubell Robinson, to develop a hardboiled Western series, a show about a "Philip Marlowe of the Old West". Macdonnell and Meston wanted to create a radio Western for adults, in contrast to the prevailing juvenile fare such as The Lone Ranger and The Cisco Kid. Gunsmoke was set in Dodge City, Kansas, during the thriving cattle days of the 1870s. Dunning, "The show drew critical acclaim for unprecedented realism."
Tales of the Texas Rangers is a 20th century Western old-time radio and television police procedural drama which originally aired on NBC Radio from 1950 to 1952 and later on CBS Television from 1955 to 1958. Film star Joel McCrea voiced the radio version as the fictitious Texas Ranger Jace Pearson, who uses the latest scientific techniques to identify criminals. His faithful horse, Charcoal (or "Charky"), helps Pearson to track down the culprits. The radio shows, some of which are available on the Internet, are reenactments of actual Texas Ranger cases.
