The exhibition marking 90 years of Radio Times opened today - with a Dalek taking pride of place at a special display dedicated to the programme that has appeared on the front cover more times than any other.

Cover Story: Radio Times At 90, which is at the Museum of London at 150 London Wall, takes visitors across the decades from the first radio transmission to today's multi-channel offerings, through landmark broadcasts, archive clips, broadcast artefacts, and original Radio Times photography and artwork.

The exclusive Doctor Who display - marking the show's 50th anniversary and its long association with the publication - features covers as well as photographs from the Radio Times archive.

People can also become a cover star for themselves by posing alongside the Dalek against a backdrop of Westminster Bridge, re-creating the 2005 "Vote Dalek!" cover, which was voted most iconic cover of all time in the Periodical Publishers Association's Great Cover Debate in 2008.

Sharon Ament, the director of the Museum of London, told Doctor Who News:The exhibition is free to go round and is open every day until Sunday 3rd November. The museum is open from 10am to 6pm, with galleries starting to close at 5.40pm.

The BBC have announced that the next star of Doctor Who is to be revealed this coming Sunday evening in a special programme to be broadcast live on BBC One at 7:00pm, and simulcast by BBC America.

Update Friday Canadian channel SPACE have confirmed they will also broadcast the live show.
Update Saturday ABC Australia have also confirmed they will broadcast the live show.

Doctor Who Live: The Next Doctor is to be presented by Zoe Ball, and is expected to feature previous Doctors, companions, special guests and 'celebrity' fans, leading up to the reveal of who has won the coveted role. Charlotte Moore, the Controller of BBC One, said:
In order to keep the half-hour show and the announcement under wraps, the BBC promoted it last week as an entertainment pilot that would pay tribute to 50 years of Doctor Who. For television schedules they instead listed a repeat of Celebrity Mastermind in the timeslot - a similar tactic was employed back in 2009 with Matt Smith's announcement, when the scheduled The Ten Doctors turned out to be a smokescreen for The Eleventh Doctor. BBC America, meanwhile, have had a repeat of The Eleventh Hour scheduled for Sunday afternoon.

Smith will also feature in Sunday's broadcast, lending advice on what it takes to play the Doctor; the show will also include interviews with Jenna Coleman and executive producer Steven Moffat, who said:

The casting process itself has been a well-kept secret, with plenty of speculation as to who will take on the role. Ben Stephenson, the Controller of BBC Drama Commissioning, commented:
As reported on Wednesday, established names such Peter Capaldi, Ben Daniels, Chris Addison, Rory Kinnear and David Harewood have all been popular choices with the betting public - though it is just as likely that a previously unconsidered name will be revealed come Sunday evening, as with Smith in 2009.

BBC America is to show the Eighth Doctor's sole TV outing to date on Saturday 31st August.

The adventure, starring Paul McGann as the Doctor, is being aired as part of the network's ongoing series Doctor Who: The Doctors Revisited marking the show's 50th anniversary, and will be broadcast following a documentary at 8pm ET/PT in which current showrunner Steven Moffat and Daphne Ashbrook, who played Dr Grace Holloway, and Yee Jee Tso, who was Chang Lee, are among those examining what made the Eighth Doctor unique. They also discuss a new take on the Doctor's old enemy the Master, played in this story by Eric Roberts.

Co-produced by the BBC, Universal Studios, 20th Century Fox, and the American network Fox, the story, written by Matthew Jacobs and directed by Geoffrey Sax, was filmed in Canada and received its world premiere in the country on 12th May 1996, subsequently being shown in the USA two days later and in the UK on 27th May, where a dedication to Jon Pertwee was added at the end, following his death exactly a week earlier.

Intended as a pilot to revive the show after it ended in 1989, it saw the Seventh Doctor, as played by Sylvester McCoy, regenerate into the Eighth. In the story, the Master attempts to take the Doctor's remaining regenerations, plunging the Earth into chaos.

Despite impressive ratings in the UK though, the American networks didn't warm to it and options weren't taken up, with the show plunged back into the wilderness - as far as the TV version was concerned - until the BBC announced in September 2003 that it would be returning.
