User:Epsilon the Eternal/Doctor Who tie-in websites

Beginning with the launch of the first series of the 2005 revival of Doctor Who, the BBC began releasing tie-in websites to coincide with both Doctor Who and Torchwood, distinct from the primary Doctor Who website. These sites were also referred to as spin-off sites and fictional sites by official sources.

Nature
The websites can be sorted into three categories: websites that are based upon counterparts within the television series; websites that have no counterpart from the television series but their respective company or group is; and those that are wholly out-of-universe websites.

The tie-in websites often directly linked to a concurrent series and/or story arc of the then-ongoing television series, such as the Who is Doctor Who? website depicting Mickey Smith's life during series one of Doctor Who and the Bad Wolf website providing an out-of-universe look on the Bad Wolf story arc, providung many false theories and explanations.

Not unlike alternate reality games, the tie-in websites employed "unfiction", a type of fiction that attempts to convince its readers that it is actually reality; this was so effective the real world United Nations began taking legal action against the U.N.I.T. tie-in website and its creators, ultimately resulting in the UNIT acronym being changed. The tie-in websites also featured certain production jokes that spurred much fan speculation.

Archiving and status
As the websites were launched in the mid-2000s, they commonly utilised software such as Adobe Flash and and, which are all now defunct and/or incompatible with older content, which has resulted in much of the non-prose material to become lost media. Furthermore, the BBC failed to pursue retaining the website domains for the majority of the tie-in websites, allowing "" to purchase the domain and either put them up for sale or to host potentially malicious content. This Wiki advises you only visit these websites through the.

, one of the only websites still hosted by the BBC is Who is Doctor Who?, however the BBC's ownership of the domain is set to expire on 29 June 2023. The domain of the U.N.I.T. website is set to expire on 23 November 2023.

Series 1
Production on the websites that coincided with series one seem to go as far back as 29 June 2004, with the registering of the domain "www.whoisdoctorwho.co.uk". The domain "www.unit.org.uk" was registered on 23 November 2004, incidentally the 51st anniversary of Doctor Who. Production wise, the website created to coincide with The Christmas Invasion was clearly created during the rest of the series one websites.

According to James Goss, the website editor four fictional websites were created in 2005, evidently not counting Bad Wolf, which contained no original fiction.

Series 2
In mid 2006, the BBC released a survey about Doctor Who, to which they received many positive responses regarding the spin-off sites with many "comments and suggestions" for the future of the sites. The official response to the survey announced that new websites were being developed. One of the most positive responses about the Doctor Who website were the "games and those fictional sites", so it was decided that for 2006, the BBC would be combining the two. James Goss, the website editor, announced in Doctor Who Magazine that each week, readers would have a mission, being sent to "a vast online world of secret organisations, [...] hidden footage, and ice cream parlours", to help Mickey Smith. Goss billed Joseph Lidster as the writer and Rob Francis as the producer, who were working in association with the games company Sequence to develop series two's tie-in websites.

Series 3
When series three began broadcasting, the BBC continued to release tie-in websites, but not to the same frequency.

Series 4
No official tie-in websites were released for series four of Doctor Who, thus ending the era.
