June

 * 25 - Donna Noble chose to take a job with H.C. Clements, rejecting her mother's suggestion that she work for another firm. An alternate timeline version of herself had been hit by a lorry a few blocks away to stop her making the other decision and altering the timeline. Rose Tyler travelled back in time from approximately two years in the future - and from the alternate timeline - to ask the alternate-Donna to pass a message on to the Tenth Doctor when she "died". (DW: The Runaway Bride, Turn Left)
 * The Tenth Doctor landed in Torchwood Tower with Rose and Jackie Tyler after tracking the ghost shifts, and was taken prisoner by Torchwood One.

Rose Tyler stumbled upon a Void Ship, discovered Mickey, back from Pete's World, and the two of them witnessed four Daleks emerging from the ship. (DW: Army of Ghosts)
 * Cybermen encountered Daleks; they fought, destroying Torchwood One. The Cybermen upgraded Torchwood staff to fight the Daleks. The Daleks identified themselves as the Cult of Skaro and used Mickey's DNA print to release millions of Daleks from the Genesis Ark to attack all life on Earth. The Tenth Doctor opened the gateway to the Void, letting the void stuff-covered Daleks and Cybermen be sucked into it (apart from the Cult, who emergency temporal shifted), before sealing itself. Rose, Jackie and Mickey were trapped in Pete's World, with no way back to their own universe, where Rose was declared dead.

After being attacked by Roboforms at the wedding reception, the Tenth Doctor, Donna and Lance went to H.C. Clements' basement. There, they travelled to a Torchwood base on the Thames Barrier. The Empress of the Racnoss force fed Lance Huon energy to awaken her children, killing him. She also sent her Webstar to attack London, but the Doctor killed the children by draining the Thames into them and the British military, ordered by "Mr Saxon", blew up the webstar. (DW: The Runaway Bride)

(DW: The Hand of Fear, School Reunion) The Doctor repaired K9 Mark III and K9 scanned the intelligence-enhancing oil in the school children's chips of Krillitane origin. The Doctor learnt they were using the children to find the Skasis Paradigm. K9 destroyed the Krillitanes, along with himself and the oil, but the Doctor gave Sarah Jane a new model, K9 Mark IV. Mickey joined the Tenth Doctor and Rose in the TARDIS. (DW: School Reunion) The Doctor had hidden several gifts for Sarah Jane inside a panel in K9 Mark IV: sonic lipstick and a wristwatch for detecting alien life. (WEB: Sarah Jane Smith website, SJA: Invasion of the Bane)
 * The events with the Sycorax on Christmas 2006 happened on "Christmas just gone" from the timeframe of this story.


 * Around this time the discovery of a bizarre message encoded as Easter eggs on seventeen different DVD releases caused a flurry of interest on the internet due to the message's cryptic nature. The message, which appeared to have been shot on film many years earlier, depicted a man with glasses conducting what appeared to be a one-sided conversation with an unknown person; he was occasionally interrupted by a young black woman. Among those interested in the message was London video store employee Larry Nightingale. Larry Nightingale began intensively studying the message, much to the annoyance of his sister, Kathy Nightingale. The Tenth Doctor and Martha Jones, following information provided to them by Sally Sparrow, investigated the Wester Drumlins estate near London, where by choice or accident they were touched by the Weeping Angels and transported to 1969; the TARDIS remained behind and was later taken into custody by London police. Sally Sparrow received a bizarre message addressed to her from the Doctor in 1969 while investigating Wester Drumlins. Sparrow learnt of the Weeping Angels, her friend Kathy Nightingale was transported back to 1920 and a policeman named Billy Shipton was sent back to 1969. Sparrow encountered an elderly Shipton, who died soon after revealing he was responsible for adding the cryptic message from the Doctor to a number of DVDs. The Easter egg mystery was solved when Sally realised the one-sided conversation was from the Doctor and directed at her. Ultimately, Sparrow stopped the Weeping Angels from capturing the Doctor's TARDIS and with the help of Larry Nightingale, sent the vessel back to 1969. After this Sally and Larry took over the DVD rental store where Larry worked, turning it into a bookstore, but Sally remained distant from Larry as she awaited the final resolution of her involvement with the time-travelling Doctor. (DW: Blink)
 * Professor Mallingan and his team of scientists began draining the power of the icy planet Asharoth hoping it would put an end to global warming on Earth. The Tenth Doctor came across Mallingan's plans and enlisted the help of one of his scientists to destroy his lab, saving Asharoth. (DWA: Cold War)

June

December

 * 24 - As a consequence of never joining H.C. Clements, the Tenth Doctor never met Donna and he died after thwarting the Empress of the Racnoss' plans. Rose Tyler, travelling between dimensions, ended up in this alternate timeline and arrived soon after the Doctor's corpse had been retrieved by UNIT. (DW: Turn Left)
 * While the Empress of the Racnoss died the same way, the TARDIS had no-one left to pilot it, let alone park it on the Cardiff Rift, so Mr Saxon would have remained as Professor Yana on Utopia.

February

 * 02 - The TARDIS fell into a parallel universe dubbed "Pete's World", where it almost died. With twenty-four hours before the TARDIS could return to its home universe, Rose discovered a living version of her dad, Pete Tyler alive and a successful businessman. Tto meet her "father", Rose snuck with the Tenth Doctor into the birthday party of a parallel version of her mother. The President of Great Britain forbade the use of John Lumic's new cybernetic lifeform, but Lumic ignored him. Mickey, mistaken for his parallel self Ricky Smith, was taken by the Preachers, who fought Lumic. The cybernetic life, dubbed Cybermen, attacked Jackie Tyler's birthday party, killing most of those inside, including the President. (DW: Rise of the Cybermen)
 * The Doctor and Rose escaped the Cyberman attack with the Preachers, Mickey and Pete, infiltrated the Cyberman factory, where every Londoner in EarPods was being upgraded, including Pete's wife, Jackie. After a Cyberman whose emotional inhibitor was broken died of shock, the Doctor sent a signal that deactivated every one of them. Mickey and Jake destroyed the transmitter controls so the hypnotised EarPod bearers could escape. Mickey also sent the Doctor the codes to break the inhibitor controls, destroying the Cybermen, and the survivors of the resistance escaped the burning factory in a zeppelin. (DW: The Age of Steel)
 * 03 - With the TARDIS cells charged, the Doctor and Rose returned to their universe. Mickey stayed behind, taking his deceased counterpart's place in shutting down more Cyberman factories. (DW: The Age of Steel)

The concept of The Companion Chronicles was to feature companions and original actors who previously had not performed their original characters due to their Doctors (specifically the first four) unavailability to the Big Finish range. The Beautiful People was an exception as it featured Lalla Ward who had been portraying Romana II for Big Finish for several years at this point, though never before in an adventure with the Fourth Doctor.

The award winner was determined by an Internet poll, and the award ultimately went to Stargate Atlantis.

Initially denied by the BBC, this was later confirmed (with the BBC including her in a cinema trailer distributed prior to the season premiere in 2008). Piper filmed scenes for four episodes, and a brief piece of footage that would be added to two others.
