[[Douglas Adams]] had contributed comedy sketches for BBC radio programmes produced by [[Simon Brett]] (including ''[[The Burkiss Way]]'' and ''[[Week Ending]]'', among others). The two of them came up with an idea for a radio science-fiction comedy series in early [[1977]].
Originally to be called ''The Ends of the Earth,'' each episode would have ended with the planet Earth meeting its demise in a different way. While writing the first episode, DouglasAdams said that he needed a character who knew what was going to happen and provide a point of view. DouglasHe decided to make this character an alien, and, remembering an idea he supposedly had had while lying drunk in a field in [[Innsbruck]], [[Austria]] in [[1971]], decided that this character would be a "roving reporter" for ''The Hitchhiker's Guide to the Galaxy.'' Later recollections by his friends at the time (see ''Hitchhiker'' by M.J. Simpson) indicate that Adams first spoke openly of the idea of "hitch-hiking around the galaxy" while on Holiday in Greece, in [[1973]].

SimonBrett and DouglasAdams both later recounted different parts of the process for getting the pilot episode recorded, including having to convince the BBC that such a programme could not be recorded with a studio audience, and their desire to record in stereo sound. In fact, to win this latter argument, Hitchhiker's was briefly classified as a Drama instead of a Comedy, as Drama programmes were allowed to be recorded in stereo, and Comedy programmes were not, in 1977.
A full series of six episodes (five new episodes, plus the pilot) were commissioned on 31 August 1977. However, Douglas had in the meantime sent a copy of the Hitchhiker's pilot episode to the BBC's [[Doctor Who]] production office, and was thus commissioned to write a four part Doctor Who serial ([[The Pirate Planet]]) a few weeks later. In addition, Simon Brett had departed the BBC, and the final five episodes in the first series were produced by [[Geoffrey Perkins]].
With conflicting writing commitments, Douglas brought his friend John Lloyd in for writing assistance on what are known as "Fit the Fifth" and "Fit the Sixth." Aside from the later Infocom computer game, (and, one could argue, the movie screenplay), this is the only instance of any form of Hitchhiker's having a co-writer credit. All of the episodes, including those completed after DouglasAdams's death, are referred to as 'Fits,' after [[Lewis Carroll]]'s "[[The Hunting of the Snark]]: an Agony, in Eight Fits." Production of "Fit the Second" was done in November, 1977. The script of the last episode of the first series (later retitled "The Primary Phase") was completed in February 1978, and production (including sound mixing and effects) was completed on [[3 March]] [[1978]].
