Who Do You Think You Are? is a British genealogy documentary series that has aired on the BBC since 2004. In each episode, a celebrity traces their family tree. It is made by the production company Wall to Wall. The programme has regularly attracted an audience of more than 6 million viewers. More than ten international adaptations of the programme have been produced.
Series one and two were broadcast on BBC Two, and the first was the channel's highest-rating programme of 2004. This led to episodes being shown on BBC One from the third series onwards. The current narrator, as of Series 14 in 2017, is Phil Davis. Mark Strong took over from David Morrissey after the first series, which was nominated for "Best Factual Series or Strand" in the 2005 BAFTAs; Cherie Lunghi was the narrator between Series 10 and 13.
In the first series, the last ten minutes of each episode featured presenter Adrian Chiles and genealogical researcher Nick Barratt giving tips on tracing a family tree. In 2007, a special episode was broadcast in conjunction with the BBC's "Family Wanted" campaign featuring Nicky Campbell, who was adopted a few days after he was born.
Series 1-11, 13 and 15 of Who Do You Think You Are? are available on DVD in the UK. In October 2007, BBC Magazines began issuing Who Do You Think You Are? Magazine, a monthly publication that includes material from the TV series.
