The Doctor derived the name from Pete Tyler, that universe's version of Rose Tyler's father, who in her universe had died in 1987. Time ran ahead in this universe, compared to the Doctor's universe, so that when it was 2007 in the Doctor's universe it was simultaneously three years later in Pete's World. (TV: Doomsday)
In this reality, all of Pete's "daft little plans" and get-rich-quick schemes worked out, effectively making him a rich and successful businessman.
Great Britain was a People's Republic with a President as head of state, instead of a monarch. Army blockades and nightly curfews were in place for lower-income areas of London. (TV: Rise of the Cybermen) Canticum was a county in the place of Kent, and there was the French Channel instead of the English Channel. (PROSE: The Turning of the Tide)
John Lumic's Cybus Industries had a high profile internationally. It created the EarPods; owned Vitex, Pete Tyler's nutritional drink company; owned International Electromatics as a front organisation; and had created CybusNet, the world's premier global information system. Secretly, Lumic had them also create the first Cybermen.
Even though the Doctor apparently did not exist in this world, or at least didn't travel to Earth in this world, the Torchwood Institute nevertheless existed (TV: Rise of the Cybermen) and Jack Harkness lived in the 21st century. (AUDIO: Poker Face) It was operating publicly, with reports it issued being mentioned in the news. The planet also had a Bio-Convention, whereby Geneva had to approve any creation of new life forms. (TV: Rise of the Cybermen)
Europe contained the nation of New Germany (TV: Rise of the Cybermen) and South America was unified in a South American State; in 2004 it lost 265,000 people across its borders and south, implied to be due to Cyberman experiments. (WC: Tardisode 5)
Torchwood was infiltrated by Cybermen, who used its technology to cross dimensions. The Institute was taken over by the People's Republic when the full scale of its activities were discovered; (TV: Doomsday) Rose Tyler later joined it. They later went on to work at creating other ways of dimensional travel. (TV: Journey's End) Due to said mass dimensional travel, ambient temperatures began to rise on Earth; three years on, the ice caps were melting. (TV: Doomsday)
The war against the Cybermen eventually became a global conflict, resulting in the Cybermen being successfully sealed in their factories. However, debate raged about whether or not the Cybermen (as former humans) could be saved, and this gave the Cyber-race time to cross realities. By 2010, as a result of the war, at least five million humans from Pete's World were converted into Cybermen. (TV: Doomsday)
Pete's World had a higher level of technological advancement in general. Such advancements included moving and speaking advertisements, and the EarPod devices which downloaded information straight into human brains. Even the Cyberman technology itself was created by humans, without any apparent use of Mondas technology.
Zeppelins served as a common means of transportation, with one soldier implying that the richest of the city tended to own them.
Automotive and engineering companies such as Mercedes-Benz and Volvo also existed in this universe, with vehicles such as the Mercedes-Benz Actros truck and Volvo BM 425 C hauler being used by Cybus Industries and its subsidiaries. (TV: Rise of the Cybermen / The Age of Steel)
Peter Tyler, unlike his counterpart, had not died in 1987. Both versions had married Jackie, though this couple did not have children; instead they had a dog named Rose. This version of Pete had made a fortune from his company, Vitex, a health drink company which Cybus owned and for which Pete himself acted as spokesman. (TV: Rise of the Cybermen) This version of Jackie underwent cyber-conversion and died. (TV: The Age of Steel) Pete later met and fell in love with the Jackie Tyler of the Doctor's universe. (TV: Doomsday)
Ricky, Mickey Smith's counterpart, led the anti-Cybus Industries activists known as the Preachers with Jake Simmonds, another Preacher. After Ricky died, Mickey decided to stay behind and take his place. (TV: Rise of the Cybermen/The Age of Steel)
Yvonne Hartman did not become a Cyberman and crossed over into N-Space to survive. She said that her Jack Harkness was better looking than the one in N-space and had a vague recollection of Ianto Jones, who made bad coffee and worked in administration. (AUDIO: Poker Face)
On 1 February 2007, the Doctor's TARDIS was catapulted into Pete's World while travelling through the Time Vortex. The TARDIS was critically drained of energy by the journey and unable to replenish itself due to the incompatibility of the ambient energy of the alternate universe. The Tenth Doctor gave away 10 years of his life to recharge a still-function artron crystal which was then used to restore the TARDIS long enough to enable it to travel back to N-Space. The first Cybermen were created by John Lumic (TV: Rise of the Cybermen) and attacked Great Britain. The Doctor and his allies eventually teamed-up and destroyed the Cybermen. The Cybermen leader, their Controller (with John Lumic's brain), perished in the destruction of his cyber-factory. After meeting his parallel counterpart Ricky Smith and being inspired by his example, Mickey Smith decided to stay in the alternate universe to take the late Ricky's place and help fight the Cybermen. (TV: The Age of Steel)
Jake Simmonds and Peter Tyler crossed over into N-Space to stop the Cyberman invasion. That universe's Jackie Tyler met the other version of Pete Tyler for the first time and decided to stay with him. Mickey Smith, Pete, and Jake returned to the other world, taking Jackie and her daughter Rose with them, stranding them after the breach closed. Rose joined the parallel version of the Torchwood Institute. Jackie and Pete conceived a child and Mickey apparently took up residence with the Tylers.
Soon after joining Torchwood and several months after Jackie became pregnant, Rose began receiving what appeared to be a message from the Tenth Doctor. With the support of her family, she travelled to Dårlig Ulv Stranden in Norway, where she briefly made contact with the Doctor so they could say goodbye to each other. (TV: Doomsday)
When Davros' reality bomb, (TV: Journey's End) also known as "the Darkness", (TV: Turn Left) was detonated, dimensions in "the whole of reality" started to collapse. (TV: Journey's End) Rose subsequently returned to the Doctor's universe. (TV: The Stolen Earth) After defeating the Daleks and preventing the reality bomb from detonating, the Tenth Doctor returned Rose and Jackie to the parallel Earth. Also left behind was the Meta-Crisis Tenth Doctor. Due to the disarming of the reality bomb by Donna Noble, the Darkness never occurred at all and this universe was saved from destruction. (TV: Journey's End)
The Cybermen from this universe survived, and later joined the Alliance. This universe, and indeed every universe, was, as the Cyber-Leader put it, "deleted" as a result of total event collapse. (TV: The Pandorica Opens) After reality was rebooted, the collapsed universes such as Pete's World were reinstated. (TV: The Big Bang)
Behind the scenes Edit
Creatures and Demons Edit
REF: Doctor Who: Creatures and Demons, a non-narrative source, theorised that Pete's World split from the universe occupying N-Space when Queen Victoria still went to Torchwood House in 1879. The Werewolf attacked the house and Queen Victoria was killed in this event.
Cybus Industries website Edit
Cybus Industries had a tie-in website, no longer hosted by the BBC as of July 2013.
The website had a collection of the CEO of Cybus Industries, John Lumic's, thoughts. He mentioned that living in an airship had its "disadvantages", such as if a dissident Cybus executive "accidentally" fell into the Grand Canyon, which in Pete's World was in the United States of Mexico, then they couldn't vote against Lumic again. Lumic corrected himself by saying, "I'm sorry, did I say disadvantages? I meant to say advantages."
The article also mentioned Lumic's dismissal of "unimportant" pressure group like the Preachers in Great Britain, or the Free Information Collectives in New Germany and "Czechoslovenia™", saying that such groups "should simply be ignored".
The website featured an interview with Lumic. When asked what the "best" decision he made was, Lumic answered with, "Assassinating the Prime Minister of the United States of Mexico". When asked the "best" and "worst" things about the BBC, Lumic simply responded that he abolished the BBC after Cybusnet became the sole global information provider.
