Drama is also broadcast, notably in The 7th Dimension segment. A long-running segment continued from Radio 7, the block airs speculative fiction, science fiction, fantasy and horror stories presented by Nicholas Briggs. The segment contains programmes including Doctor Who audio dramas starring Paul McGann as the Eighth Doctor, as well as programmes imported from overseas including American broadcasts "The Twilight Zone" and "Garrison Keillor's Radio Show" as well as Stuart McLean's "Vinyl Cafe" from Canada. The 7th Dimension was originally broadcast daily, but has now been reduced to weekends-only. With increasing repeats of old Radio 4 documentaries, interviews and "educational/cultural" programmes, some listeners are concerned that the station's original mandate to provide comedy, drama and entertainment is being increasingly sidelined.
