Blue Peter

Blue Peter was a popular BBC children's television programme.

Faction Paradox attacked the Blue Peter garden in 1996. This caused a far more intense psychological reaction than any direct assault on the people's psyche. (PROSE: Interference - Book Two)

In 2006, an alien ship crashed into the Thames. Blue Peter presenter Matt Baker did a feature on how to make an alien ship cake. (TV: Aliens of London) Following the feature, a BBC internal memo questioned whether it was appropriate to promote the creation of "space confectionary" for children, stating that it could be seen as pandering to incoming Prime Minister Joseph Green - the former Chairman of the Parliamentary Commission on the Monitoring of Sugar Standards in Exported Confectionary.

In the 2000s, Maria Jackson watched an episode in which the presenters Gethin Jones and Konnie Huq promoted the Bane's Bubble Shock! soft drink. (TV: Invasion of the Bane)

Overview
The actor Sophie Aldred, had won two Blue Peter badges in her youth and was entitled to wear them on-screen, according to the BBC's strict regulations regarding the use of Blue Peter badges. (BBC DVD: The Horns of Nimon)

For many years, the series also had another connection to the franchise in the form of co-host Peter Purves, who appeared on Blue Peter for many years after his tenure playing Steven Taylor in Seasons 2 and 3.

Doctor Who Magazine explored the programme and its vast connections to Doctor Who in its 334th issue.

Clips from missing episodes
A 1973 instalment of Blue Peter marking the tenth anniversary of Doctor Who included many excerpts from the William Hartnell and Patrick Troughton eras; due to the BBC's then-ongoing practice of junking old episodes, these clips are in many cases the last surviving remnants of these episodes. These include such significant moments as the death of Katarina in The Daleks' Master Plan (which was aired on Blue Peter primarily because it featured then-co-host Peter Purves during his tenure as companion), and the regeneration of the First Doctor into the Second from The Tenth Planet.

These clips survived beyond their initial Blue Peter broadcast thanks to long-time showrunner Biddy Baxter's staunch policy of archiving every episode of Blue Peter.

Design a monster competitions
Blue Peter has run contests over the years involving Doctor Who.

A design-a-monster competition was held on Blue Peter in 1967. Among some 250,000 entries, three winners were selected: the Hypnotron (by Paul Worrall), the Steel Octopus (by Karen Dag), the Aqua Man (by Stephen Thompson). While they did not appear on Doctor Who, prop versions of the three monsters were constructed. Contrary to rumour, the Krotons did not originate in this competition. (REF: The Doctors: The Archive)

The design for the Abzorbaloff from 2006's Love & Monsters originated in a Blue Peter "design your own monster" competition, won by nine-year-old William Grantham.

TARDIS design competition
In late 2009-early 2010, a Blue Peter contest invited viewers to submit designs for a new TARDIS control console to be featured in an upcoming episode. On 17th February 2010, Matt Smith chose twelve-year-old Susannah Leah's design as the winner; it was announced that Neil Gaiman's episode in Series 5 would feature this design in some way. However, the episode's funding ran out of money and it was pushed back to Series 6, when it appeared as The Doctor's Wife and featured Leah's design as the Junk TARDIS console. 

Impact on casting
Blue Peter directly influenced the casting of one character on Doctor Who. In 2006, a viewer contest was held for under-14s, with the prize being a chance to appear in an upcoming episode. The winner, John Bell, not only appeared in TV: Utopia, but in a significant role as Creet, a young boy Martha Jones befriends who later is transformed into a Toclafane.

Other information and trivia
When two Dalek props were stolen, Blue Peter ran an appeal to bring them back. They were returned within twenty-four hours.
