The second series of British science fiction programme Doctor Who began on 25 December 2005 with the Christmas special "The Christmas Invasion". A regular series of thirteen episodes was broadcast weekly in 2006, starting with "New Earth" on 15 April and concluding with "Doomsday" on 8 July. In addition, two short special episodes were produced; a Children in Need special and an interactive episode, as well as thirteen minisodes titled Tardisodes. It is the second series of the revival of the show, and the twenty-eighth season overall.
It is the first series to feature David Tennant as the tenth incarnation of the Doctor, an alien Time Lord who travels through time and space in his TARDIS, which appears to be a British police box on the outside. The Doctor continues to travel with his companion Rose Tyler (Billie Piper), with whom he has grown increasingly attached. They also briefly travel with Rose's boyfriend Mickey Smith (Noel Clarke), and Rose's mother Jackie (Camille Coduri). The series is connected by a loose story arc consisting of the recurring word "Torchwood". This is also the first series to be preceded by a Christmas special, the success of "The Christmas Invasion" led to the Christmas special becoming an annual tradition.
Russell T Davies returned as head writer of the series. Phil Collinson produced all episodes, with Julie Gardner serving as executive producer. Music for the series was composed by Murray Gold. A majority of filming took place in Cardiff, Wales. The series was acclaimed by critics and won multiple awards, including five at the BAFTA Cymru Awards.
