Blue Peter

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

History
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)

In 2008, 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)

Other information
Ace, who left Earth in 1987, wore two Blue Peter badges on her jacket; one standard blue badge, one silver. (TV: Remembrance of the Daleks) One of them had been awarded for heroic achievement. (PROSE: Cat's Cradle: Time's Crucible)
 * 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)

Overview
In real life, Blue Peter has had a longtime association with Doctor Who. It was used on many occasions to promote the series and upcoming episodes, monsters and special events, including the debuts of Peter Davison and Sylvester McCoy, who spoke about taking up the role of the Doctor. Historically, the series has proven valuable for not only featuring contemporary interviews with actors and behind-the-scenes personnel from the series, but for also providing glimpses into production history.

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.

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. The design for the Abzorbaloff from 2006's Love & Monsters originated in a Blue Peter "design your own monster" competition. Contrary to rumour, the Krotons did not originate in a 1967 competition; a design-a-monster competition was held, but the winning design did not appear on the show.

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. 

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.
