'''''The Hitchhiker's Guide to the Galaxy''''' is a [[comedy science fiction]] franchise created by English author [[Douglas Adams]]. It originated as a radio comedy series broadcast on [[BBC Radio 4]] and was later adapted into a bestselling "trilogy" of five novels (plus a sixth by another author), a television series, a 2005 feature film, stage plays, a text adventure video game, and various other media.

The series is known for its absurd humor, satirical take on life, the universe, and everything, and iconic elements such as the electronic book "The Hitchhiker's Guide to the Galaxy" (with the words "**Don't Panic**" inscribed in large, friendly letters on the cover), the depressed robot [[Marvin the Paranoid Android]], and the answer to the Ultimate Question of Life, the Universe, and Everything: **42**.

== Overview and Plot ==

The story follows [[Arthur Dent]], an ordinary Englishman whose house (and later the entire planet Earth) is about to be demolished. Arthur is rescued by his friend [[Ford Prefect]], who turns out to be an alien researcher for the titular ''Hitchhiker's Guide to the Galaxy'', an electronic book that serves as the most popular travel guide in the universe.

Together, they embark on a series of misadventures across the galaxy, encountering bizarre characters such as:
* [[Zaphod Beeblebrox]], the two-headed, three-armed President of the Galaxy
* [[Trillian]] (Tricia McMillan), an astrophysicist
* [[Marvin the Paranoid Android]], a chronically depressed robot
* [[Slartibartfast]], a planet designer who won an award for Norway's fjords

The narrative satirizes bureaucracy, philosophy, religion, technology, and human (and alien) folly through rapid-fire wit and logical absurdity.

== History ==

The franchise began as a six-episode radio series (the "Primary Phase") broadcast on BBC Radio 4 in 1978, followed by a "Secondary Phase" in 1980. Douglas Adams adapted the first four radio episodes into the first novel, which was published in the UK on 12 October 1979 by Pan Books.

Adams described the series as a "trilogy in five parts." The books were published as follows:
* ''The Hitchhiker's Guide to the Galaxy'' (1979)
* ''The Restaurant at the End of the Universe'' (1980)
* ''Life, the Universe and Everything'' (1982)
* ''So Long, and Thanks for All the Fish'' (1984)
* ''Mostly Harmless'' (1992)

After Adams' death in 2001, [[Eoin Colfer]] wrote a sixth book, ''And Another Thing...'' (2009), with the approval of Adams' widow.

Later radio series (Tertiary, Quandary, and Quintessential Phases) adapted the remaining books in 2004–2005.

== Adaptations ==

* '''Radio''': Original BBC Radio 4 series (1978–1980, plus 2004–2005 phases)
* '''Television''': BBC Two six-episode series (1981), notable for its low-budget special effects and faithful (yet distinct) adaptation
* '''Film''': 2005 live-action film directed by Garth Jennings, starring Martin Freeman as Arthur Dent, Mos Def as Ford Prefect, Sam Rockwell as Zaphod, and Zooey Deschanel as Trillian. It received mixed reviews but introduced the story to a new audience.
* '''Stage''': Multiple theatrical adaptations starting in the early 1980s
* '''Video Game''': 1984 text adventure game by Infocom, co-designed by Adams, known for its difficulty and humor
* '''Other''': Comic books, towel merchandise (inspired by the Guide's advice that a towel is the most useful thing a hitchhiker can carry), and Towel Day (celebrated annually on 25 May)

== Themes and Style ==

The series is celebrated for its dry British wit, philosophical undertones, and critique of modern society wrapped in galactic absurdity. Famous elements include:
* The [[Babel fish]] (a universal translator)
* The Infinite Improbability Drive
* Vogon poetry (the third worst in the universe)
* The number **42** as the Answer to the Ultimate Question (though the Question itself remains unknown)

Adams' writing style features rapid dialogue, tangents, and footnotes from the Guide itself.

== Cultural Impact ==

''The Hitchhiker's Guide to the Galaxy'' has sold millions of copies worldwide and remains a cornerstone of comedic science fiction. It inspired phrases like "Don't Panic," "Mostly Harmless," and Towel Day. The work has been translated into dozens of languages and continues to influence writers, comedians, and technologists (including references in AI and space exploration contexts).

The franchise is often praised for making complex ideas accessible and entertaining while highlighting the ridiculousness of existence.
