The first two episodes of the show were made by independent production company
Celador. Their contract to produce the show expired after the broadcast of the second episode on 27 December 1992 and was not renewed, leaving the BBC to produce the show themselves from 1994 to 2001. The shows carried a strong BBC theme, most notably throughout the mid-90s where the set was supposedly the BBC archive, and the opening titles consisted of a mysterious figure entering the
BBC Television Centre and retrieving archive footage from a safe. ==Transmissions==
