"Hour 25" was one of the longest-running science fiction radio programs, surpassed by only "Hour of the Wolf", and surpassing "Shockwave Radio Theater"'s 28 year run. In its first years, "Hour 25" functioned almost as a science fiction "web page" for the Los Angeles area fan base, before computer technology made it much simpler to keep up-to-date on news and events in the relatively small world of science-fiction fandom. It was also one of the earliest programs to be taken seriously by both authors and publishers.
