Who Do You Think You Are? (British TV series)

Who Do You Think You Are? is a British genealogy documentary series that has aired on the BBC since 2004, in which celebrity participants trace their family history. 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.

Episodes
The first two series 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 when he was just a few days old.

The theme tune was composed by Mark Sayer-Wade, who also provided the background music for earlier episodes. The music in later episodes was provided by Julian Hamlin, Edmund Jolliffe, Mark Russell. Mike MacLennan is the current composer, as of Series 20 in 2023.
