"Greatest Moments", the "2010 specials", and "My Sarah Jane" primarily consisted of interviews and clips from the series featuring no primary host.

The following table dictates the season or series in question; singular specials are not included in episode counts.

The first season was narrated by Simon Pegg (who played the Editor in "The Long Game") and produced and directed by Gillane Seaborne, airing at 7.45 pm.

The first was broadcast on the evening of the first episode, "Rose", and was narrated by David Tennant, prior to his being named as the Tenth Doctor.

Thirdly, a special DVD-only episode of the series, containing behind-the-scenes information on "The Christmas Invasion", was also made by the production team for release on the set.

The final episode, which aired on 1 October 2011, incorporated a mini-episode, Death is the Only Answer, written by a group of schoolchildren who won a contest co-sponsored by Confidential.

Initially, repeat airings of the series were the full length episodes; however, beginning with Episode 6, BBC Three broadcast fifteen-minute versions, entitled Doctor Who Confidential: Cut Down, containing only the new series-related footage were released on the Series 1 DVD box set.

Due to a wide range of schedule changes that either delayed or altered transmission of Doctor Who, the series aired at various times during its run.

The episode running length was increased to 45 minutes for the third series, with 30-minute and 15-minute versions also prepared for broadcast.

A third special commemorating the death of Elisabeth Sladen was produced by the Confidential team as well and was aired on CBBC.

On 28 September 2011, a few days prior to the broadcast of the Confidential episode to accompany season 6 finale "The Wedding of River Song", BBC controller Zai Bennett announced the cancellation of the series as a cost-cutting measure.

[6] Within 24 hours of the show being officially cancelled, pages on both Facebook and Twitter were established in an attempt to save it, both with links to an online petition that gained over 20,000 signatures within the same period,[7] and eventually garnered over 50,000.

[8] People involved with the show such as writers Neil Gaiman ("The Doctor's Wife") and Tom MacRae ("The Girl Who Waited") expressed their concern with the axing of the programme,[9] as did lead actor Matt Smith.

[8] In 2012, seventh series executive producer Caroline Skinner announced that smaller behind-the-scenes featurettes would be released on the BBC's Doctor Who website to make up for Confidential's cancellation.

The BBC Radio 7 broadcasts of Big Finish Doctor Who audio dramas are followed by a 15-minute backstage programme called Beyond the Vortex.
