Tardisode

Tardisodes were mini-episodes which served as prologues for each episode of Series 2 of the BBC Wales version of Doctor Who. They were made available serially, with a new one debuting in the week prior to the episode to which they were attached. They were primarily meant to be seen on mobile telephones, and were released to paying phone subscribers first. As each week progressed, however, the BBC did make them available as webcasts.

Format and crew
Each Tardisode was approximately one minute in length and was optimized for quick mobile download. Though exact technical specifications are not curently known, they were of an obviously inferior technical standard to a televised episode.

They served as an early "proving ground" for two people who would later become more significant to the televised Doctor Who universe. Their lone writer was Gareth Roberts, who, at the time, had only written the interactive game, Attack of the Graske. And they were all directed by Ashley Way, who would later go on to helm several episodes of Torchwood and Matt Smith-era Doctor Who.

They did not feature the Doctor or Rose Tyler, but focused on other characters and monsters. Most served to set up elements of the episode's story line; in one case, School Reunion, the Tardisode was a direct prequel, explaining how Mickey Smith recruited the Doctor and Rose Tyler to investigate the school in question.

As no Tardisode was made for The Christmas Invasion, there were thirteen Tardisodes in all.

Current availability
The BBC chose not to include the Tardisodes with the DVD release of Series 2. They are also no longer easily accessible on the BBC's website. As of 2010, they cannot be found linked in any way to the main Doctor Who website. Instead, they exist as programmes which can be selected on a BBC media player. However, the format in which they are retained is specialized, and requires many computer users to use workaround software.

These facts render the mini-episodes legally inaccessible to most viewers at the current time. Despite their relative scarcity, however, they are not, presumably, missing episodes, as the BBC almost certainly retain them in BBC Film and Videotape Library or a similar facility at BBC Wales.

Concept future
No Tardisodes were produced beyond the 2006 series. In 2007, the BBC's annual report said that the Tardisodes "were not the hit we expected although they were popular on broadband", presumably why they were discontinued after series 2.

BBC has offered a further attempt at multimedia narrative, with "Music of the Spheres", a special mini-episode meant for consumption by a live audience at the BBC Proms.

Series 6 featured a small series titled "The Prequels", which was similar in concept.

Continuity

 * In an interview with Noel Clarke for Totally Doctor Who, he revealed that his hair was noticeably shorter during the filming of Tardisode 3 than in the episode it accompanied, "School Reunion". For this reason, to maintain continuity, he wears a hat for the duration of the TARDISODE.
 * Images of the Doctor are shown in two of the shorts. In TARDISODE 10 a drawing of him is seen on a computer; in TARDISODE 12 he appears in drawings and in an antique photograph.
 * TARDISODE 12 references Tooth and Claw and The Christmas Invasion.

Production

 * Before a TARDISODE, the time vortex is briefly seen. If the main episode is set in the past, the vortex is blue and if the main episode is set in the present or future, the vortex is red.
 * A new set was built for Tardisode 4.
 * Tardisode 8 was filmed entirely in the BBC Wales Canteen.
 * As of 2006, there is no "East London Council" as seen in 2012 in Tardisode 11, although various amalgamations of London borough councils have been proposed.
