Rebroadcast in this country of original BBC radio programming is nothing new now, but in the 1970s and 80s it was fairly novel because at that time there was still some original programming being produced for radio by American public broadcasters and private outfits. There was Earplay on NPR, which were dramas based on original material and adaptations, and there was the CBS Radio Mystery Theater, a program of thrillers. Those American radio programs shut down in the 1980s, and since then very little original programming has come out of America. Britain, on the other hand, has a comparatively lively radio program production lineup, and as proof there is the sixth series of The Hitchhiker’s Guide to the Galaxy (with a cameo by renowned cosmologist Stephen Hawking no less), airing in March 2018, forty years on from the first series. Fans of the show on this side of the Atlantic are glad the BBC radio crews are still at it, and if the latest series is anywhere near as enjoyable a listen as the first series, then their efforts will have been well worthwhile.
