Today sees the Tenth Doctor regenerate into the Eleventh, only the tenth time in Doctor Who's forty-seven year history that the Doctor has regenerated.

It marks the last story for the Tenth Doctor as played by David Tennant, who leaves the series after four years in the role and with 47 episodes under his belt. Tennant departs at the peak of his popularity, and was recently voted the best Doctor ever by the readers of Doctor Who Magazine. His dedication to the role has been tremendous, and he has led the cast of a series that scores incredibly high in the audience appreciation figures. His popularity is such that the BBC made him the centrepiece of its Christmas schedule; he is the first Doctor ever to have featured in a BBC One ident.

Today also marks the end of the Russell T Davies and Julie Gardner era of the series. Gardner and Davies have been involved with the show since the return was first mooted in 2003. Together they have been responsible for the realisation of the revived series and have turned Doctor Who into one of the biggest BBC properties in the first decade of the 21st Century. They have been responsible for 60 episodes and have made Doctor Who must-see television which regularly charts in the top ten programmes of the week. They have cast two Doctors, Christopher Eccleston and David Tennant, and created two spin-offs, Torchwood and The Sarah Jane Adventures, both of which have had tremendous success and are due to be commissioned for their fourth series.

All three leave a strong legacy for the new production team to build on in 2010 as the series returns with a new Doctor and a new Executive Producer in the Spring.

BBC News have uploaded this morning's interview with David Tennant. The item contains two clips from The End of Time Part Two, which contain spoilers from Part One.

Tennant later appeared on a BBC Radio 5 Live phono-in, which is available on the BBC iPlayer.

BBC News have also published an article on regenerations past and present.

David Tennant has also talked to MTV about his 'Doctor Who' Mementoes.

The new Radio Times marks Matt Smith out as one of the ten people to watch in 2010. In the magazine, new executive producer Steven Moffat tells why viewers will be transfixed by Smith's portrayal of The Doctor. He describes him as a strong quiet man who conveys gravitas perfectly. "His most powerful moments are when he is very very quiet. in a way that a very powerful person can be... It's all implied strength rather than demonstrated bluster."

Moffat describes Smith as very much the 'nutty professor' Doctor whom the camera adores. "You'll be seeing a lot of that face, suffering, in close-up."

Smith's first series as the Doctor is due to be aired in the UK in the spring.

A new clip from The End of Time - Part Two has been made available today. An audio version of the clip was played on Who on Who on BBC Radio 2 and the full version was seen later on Alan Carr Chatty Man.

David Tennant and Catherine Tate have sparked off a debate on how to pronounce 2010. The topic was one of those discussed in last Saturday's Radio 2 show hosted by the pair when Tennant claimed that the BBC compliance rules insisted on twenty-ten while guest Bernard Cribbins said older people would prefer two thousand and ten. Although the BBC later denied there was any rule, the discussion has been picked up by many papers including The Telegraph in the UK and several papers around the world.

Meanwhile The Daily Mail, always quick to find a story to knock the BBC, has claimed that Tennant has taken over the BBC this Christmas. The paper claims the actor will have made over 75 appearances on the BBC over the holiday period and accuses the BBC of freezing out young acting talent by giving audiences an overdose of Tennant. Conservative MP Nigel Evans has been quoted by the paper as saying : "Sadly the BBC seem to have got themselves stuck in the rut of chasing ratings and going populist". he added "Their public service remit was always about bringing on fresh talent", perhaps forgetting that relative newcomer and 'fresh talent' Matt Smith takes over the role of The Doctor shortly.

The End of Time Part One received an AI figure of 87.

The Appreciation Index, or AI, figure is a measure of how much the audience liked a programme. A score over 85 is considered excellent. Doctor Who had the highest score of the day on BBC One or BBC Two. The only programme to score higher on the main five channels was the film Gladiator on ITV1, which scored 89 with a much lower audience.

The Sunday night, BBC Three repeat of The End of Time Part One was watched by 590,000 viewers according to unofficial overnight figures. The programme was the 11th most watched multi channel programme for the day and had a share of 2.7%.

With figures available for the whole week, the Christmas day showing remains as the third most watched programme. Final figures will include those who record the programme and watch it within one week, and it is possible the programme will move into second place once these are released next week. The Appreciation Index figure should be available Tuesday.

The BBC has uploaded an exclusive clip from Part Two of The End of Time onto the official website. You are strongly advised not to click on the link if you have not seen Part One as it contains major spoilers from the end of Part One. The clip is only available on the official site in the UK.

David Tennant has spoken of his love for Doctor Who and how it lead him to choose acting for a career. Speaking on Desert Island Discs on BBC Radio Four, to be broadcast Sunday morning, he tells how it was watching Jon Pertwee in the role as a child, that made him want to go into the profession. He also tells of meeting Tom Baker while Baker was playing the fourth Doctor.

Various papers have reported the UK ratings for Christmas day with The Times describing the figures as disappointing for the BBC, while the Guardian concentrated on the BBC's dominance of the chart. The Mirror focused on EastEnders, but describes The End of Time as terrific, while The Star discribed the Christmas audiences for BBC One as huge.

David Tennant and Catherine Tate today stood in for Jonathan Ross on his Radio 2 show.

Guests included Bernard Cribbins and fifth Doctor Peter Davison.

The programme is available worldwide via the BBC iplayer for the next seven days.

10.0 million people watched the first part of The End of Time on BBC One yesterday, according to unofficial overnight figures.

Doctor Who was the third most-watched programme of the day, behind soap opera EastEnders and sitcom The Royle Family, and achieved a 42.2% share of the total television audience.

Although the raw figure is down on the previous two years, it still makes The End of Time, Part One one of the highest-rating episodes of the series since it returned in 2005. An additional 340,000 viewers watched the programme on the BBC HD channel. If HD figures are added to the BBC One figures then both Doctor Who and The Royle Family got 10.4 million watching.

The day was a triumph for the BBC, with BBC One taking nine of the top ten Christmas Day spots.

On the digital channels Doctor Who Confidential had 0.58 million watching and was the fourth highest multi channel programme of the day.

Final figures, which will include those who record and watch the programme within one week, will be released by BARB in January.

Russell T Davies has told The Guardian how he took Pop Idol as his inspiration for the rebirth of Doctor Who. He tells the paper how he used to go to a friend's house to watch the final with several others. He says "I wanted to do that with drama. If we could have the voice at the beginning of The X Factor introducing each episode I would do it."

In a somewhat different interview, Davies has caused controversy by voicing his concerns about the future of the BBC, should the Conservative Party win the 2010 General Election. Davies told The Mirror he fears the BBC will be dismantled by the Tories and is convinced that a move to freeze the licence fee by the Conservatives will be the beginning of the end for the corporation. "They'll dismantle it slowly. It'll get smaller and smaller until it just supports Radio 4 and some news. I'll come back and fight them at the barricades. I feel a bit like Alan Bennett, who said his favourite things about Britain were the BBC and the NHS." Davies's remarks were picked up by many UK papers, but not it seems in Conservative Central office. When journalist Matt Withers rang their press office for a statement he was told they wouldn't comment on it, because "Mr Davies is a backbench MP and, as such, his opinion isn't necessarily party policy".

Veteran actress June Whitfield has told The Sun of a particular problem she had while recording The End of Time, when the script called for her to goose David Tennant, "Well, he is so thin that it was difficult to find the bottom!" says Whitfield, 84. "But this was in the script, I promise."
