''. The Doctor has attempted to repair the chameleon circuit, unsuccessfully in '' Logopolis'' (1981) and with only temporary success in '' Attack of the Cybermen'' (1985). In " Boom Town", the Doctor reveals that he has stopped trying to repair the circuit as he has become fond of its appearance. The other TARDISes that appear in the series have chameleon circuits that are fully functional. The TARDIS is famously "bigger on the inside". A much larger control room lies inside the police box, at the centre of which is a console for operating the TARDIS. In the middle of the console is a moving tubular device called a time rotor. The presence of a physically larger space contained within the police box is explained as "dimensionally transcendental", with the interior being a whole separate dimension containing an infinite number of rooms, corridors and storage spaces, all of which can change their appearance and configuration. The TARDIS also allows the Doctor and others to communicate with people who speak languages other than their own, as well as turn all written languages to English. The translation circuit has been explored in comparison with real-world machine translation, with researchers Mark Halley and Lynne Bowker concluding that "when it comes to the science of translation technology, ''Doctor Who'' gets it wrong more often than it gets it right. However, perhaps we can forgive the artistic license if we recognise that, as in other science fiction works, the presentation of some type of ubiquitous translation tool is necessary to explain to the audience how people from other countries, time periods, and even other worlds, can understand each other and indeed appear to speak (mostly) flawless English." The TARDIS is also able to generate a "perception filter" that causes people to ignore it, thinking that it is normal.


Conceptual history


Exterior design

When ''Doctor Who'' was being developed in 1963 the production staff discussed what the Doctor's time machine would look like. To keep the design within budget it was decided to make the outside resemble a police telephone box, a common piece of

staff writer, Anthony Coburn, who rewrote the programme's first episode from a draft by C. E. Webber. While there is no known precedent for this notion, a November 1960 episode of the popular radio comedy show '' Beyond Our Ken'' included a sketch featuring a time machine described as "a tall telephone box". The concept of a cloaking mechanism (later referred to as the "chameleon circuit") was devised to explain this. In the first episode, ''

'' (1963), the TARDIS is first seen hidden in a London scrapyard in 1963, and after travelling back in time (" The Cave of Skulls") to the Paleolithic era, the police box exterior persists. In a subsequent story, '' The Time Meddler'' (1965), the First Doctor explains that the TARDIS should automatically adopt a disguise, such as a howdah (a carrier on the back of an Indian elephant in the Indian Mutiny) or a rock on a beach. Accounts differ as to the origin of the police box prop. While the BBC asserts that it was constructed specially for ''Doctor Who'', it has been claimed that the box was a reused prop from the BBC television police dramas '' Z-Cars'' or ''

The dimensions and colour of the TARDIS police box props used in the series have changed many times, as a result of damage and the requirements of the show, and none of the BBC props has been a faithful replica of the original MacKenzie Trench model. Numerous details have been altered over time, including the shape of the roof, the signage, the shade of blue paint, the presence of a

Interior design

The TARDIS console room was designed for the first episode by set designer Peter Brachacki and was unusually large for a BBC production of this time. It was noted for its innovative, gleaming white "futuristic" appearance. Like the police box prop, the set design of the TARDIS interior has evolved over the years. From the inception of the show in 1963 up until the end of the " classic series" in 1989, the design of the TARDIS console room remained largely unchanged from Brachacki's original set, a brightly lit white chamber, lined with a pattern of roundels on the walls and with a central hexagonal console which contained a cylindrical "time rotor" that moved when the TARDIS was in transit. Numerous alterations were made to the central console and to the layout, but the overall concept remained constant. In Season 14 (1976–77), a dark wood-panelled "Control Room Number 2" was briefly used for a few episodes, but the white console room set was reinstated in Season 15, due to damage to the set. After the cancellation of the television show, a radically redesigned TARDIS set was used in the 1996 TV movie, heralding a move to a more

Depiction of time travel

The production team conceived of the TARDIS travelling by dematerialising at one point and rematerialising elsewhere, although sometimes in the series it is shown also to be capable of conventional space travel. In the 2006 Christmas special, " The Runaway Bride", the Doctor remarks that for a spaceship, the TARDIS does remarkably little flying. The ability to travel simply by fading into and out of different locations became one of the trademarks of the show, allowing for a great deal of versatility in setting and storytelling without a large expense in special effects. The distinctive accompanying sound effect – a cyclic wheezing, groaning noise – was originally created in the BBC Radiophonic Workshop by sound technician Brian Hodgson by recording on tape the sound of his mother's house key scraping up and down the strings of an old piano. Hodgson then re-recorded the sound by changing the tape speed up and down and splicing the altered sounds together. When employed in the series, the sound is usually synchronised with the flashing light on top of the police box, or the fade-in and fade-out effects of a TARDIS. Writer Patrick Ness has described the ship's distinctive dematerialisation noise as "a kind of haunted grinding sound", while the ''

The sound of the Doctor's TARDIS featured in the final scene of the '' Torchwood'' episode " End of Days" (2007). As Torchwood Three's hub is situated at a rift of temporal energy, the Doctor often appears on Roald Dahl Plass directly above it in order to recharge the TARDIS. In the episode, Jack Harkness hears the tell-tale sound of the engines, smiles and afterwards is nowhere to be found; the scene picks up in the

Former companion Sarah Jane Smith has a diagram of the TARDIS in her attic, as shown in '' The Sarah Jane Adventures'' episode " Invasion of the Bane" (2007). In the two-part serial '' The Temptation of Sarah Jane Smith'' (2008), Sarah Jane becomes trapped in 1951 and briefly mistakes an actual police public call box for the Doctor's TARDIS (the moment is even heralded by the Doctor's musical cue, frequently used in the revived series). It makes a full appearance in '' The Wedding of Sarah Jane Smith'' (2009), in which the Doctor briefly welcomes Sarah Jane's three adolescent companions into the control room. It then serves as a backdrop for the farewell scene between Sarah Jane and the Tenth Doctor, which echoed nearly word-for-word her final exchange with the Fourth Doctor aboard the TARDIS in 1976. It reappears in '' Death of the Doctor'' (2010), where it is stolen by the Shansheeth who try to use it as an immortality machine, and transports Sarah Jane, Jo Grant and their adolescent companions ( Rani Chandra, Clyde Langer and Santiago Jones).


Theatrical films

The TARDIS appears in the two film productions, '' Dr. Who and the Daleks'' (1965) and '' Daleks' Invasion Earth 2150 A.D.'' (1966). In both films the Doctor, played by Peter Cushing, is an eccentric scientist who invented the TARDIS himself.


Cultural impact


Merchandising

As one of the most recognisable images connected with ''Doctor Who'', the TARDIS has appeared on numerous items of merchandise associated with the programme. TARDIS scale models of various sizes have been manufactured to accompany other ''Doctor Who'' dolls and action figures, some with sound effects included. Fan-built full-size models of the police box are also common. There have been TARDIS-shaped video games, play tents for children, toy boxes, cookie jars, book ends, key chains, and even a police-box-shaped bottle for a TARDIS bubble bath. The 1993 VHS release of '' The Trial of a Time Lord'' was contained in a special-edition tin shaped like the TARDIS. With the 2005 series revival, a variety of TARDIS-shaped merchandise has been produced, including a TARDIS coin box, TARDIS figure toy set, a TARDIS that detects the ring signal from a mobile phone and flashes when an incoming call is detected, TARDIS-shaped wardrobes and DVD cabinets, and a USB hub in the shape of the TARDIS. The complete 2005 season DVD box set, released in November 2005, was issued in packaging that resembled the TARDIS. One of the original-model TARDISes used in the television series' production in the 1970s was sold at auction in December 2005 for £10,800.


BBC trademark

In 1996 the BBC applied to the UK Intellectual Property Office to register the TARDIS as a

Legacy police boxes

A number of legacy police boxes are still standing on streets around the United Kingdom. Although now no longer used for their original function, many have been repurposed as coffee kiosks, and are often affectionately referred to as TARDISes. A police box in the Somerton area of Newport in South Wales is known as the Somerton TARDIS.
