The stories take place in and around Dodge City, Kansas, during the settlement of the American West. The central character is lawman Marshal Matt Dillon, played by William Conrad on radio and James Arness on television. When aired in the UK, the television series was initially titled Gun Law, later reverting to Gunsmoke. Wikipedia
(the teaser of the very first episode, "Matt Gets It.") John Wayne: Good evening. My name's Wayne. Some of you may have seen me before. I hope so. I've been kicking around Hollywood a long time. I've made a lot of pictures out here. All kinds. Some of them have been westerns and that's what I'm here to tell you about tonight. A western. A new television show called "Gunsmoke". When I first heard about the show "Gunsmoke", I knew there was only one man to play in it. James Arness. He's a young fellow, and maybe new to some of you. But I've worked with him and I predict he'll be a big star. And now I'm proud to present "Gunsmoke".
