2000s

On Earth, the 2000s, or the 00s were the first decade of the 21st century.

The 2000s brought an increasing number of widely seen alien encounters. This led to widespread knowledge of alien life. Following the public revelation of alien life in the late 2000s suicide rates doubled. (TW: Children of Earth: Day One)

Behind the scenes

 * The first half of the decade saw several "false alarms" of new Doctor Who TV and film productions.
 * Meanwhile, BBC Books continued its prolific lines of Doctor Who novels.
 * Telos Publishing obtained the licence to produce original novellas based upon Doctor Who.
 * Bernice Summerfield, no longer the star of her own Virgin Publishing novels, was featured in numerous novels, short stories and audio dramas produced by Big Finish.
 * The BBC experiments with new media, producing several Doctor Who webcasts consisting of original stories featuring original series cast members. In 2003, a webcast entitled Scream of the Shalka introduces Richard E. Grant as the voice of the Ninth Doctor.
 * In late 2003, BBC Wales announces that it will be producing a new live-action Doctor Who series, with Christopher Eccleston as the Ninth Doctor (the Richard Grant version of the character is abandoned). The series debuts in the spring of 2005 and almost instantly reinstates Doctor Who as a national institution.
 * BBC Books discontinues its line of Eighth Doctor and Past Doctor novels in favor of a new line of hardcover fiction featuring the Ninth (and later the Tenth) Doctor.
 * Big Finish Productions obtained the licence to publish the Short Trips book series.
 * After one season, Eccleston leaves Doctor Who and David Tennant is introduced as the Tenth Doctor.
 * Two spin-off series are launched: Torchwood and The Sarah Jane Adventures.
 * In 2008, Tennant announces his departure from Doctor Who. Matt Smith, a largely unknown actor is cast as the Eleventh Doctor at the age of 26; he later debuts in 2010.
 * After four extremely successful seasons under the watch of Russell T Davies, Doctor Who goes on partial hiatus for 2009, producing a number of specials in lieu of a full season. This is to allow Davies to hand over production duties to Steven Moffat, and also pave the way for Tennant's departure.
