Having dropped hints of information regarding the 50th Anniversary special of Doctor Who gradually over the past few months, BBC Worldwide decided to wait until after the media swarm that is San Diego Comic-Con to release their latest news: Doctor Who's 50th Anniversary Special will be simulcast internationally. Quite literally a simultaneous broadcast, every single country broadcasting the episode will do so at the same time, in what is believed will be the biggest simulcast in history; it has also been reported that the special will be watched by an estimated 100 million viewers in the 200 countries that have agreed to take part. In perhaps the true meaning of wibbly-wobbly-timey-wimey, when British viewers are watching the special during its traditional Saturday tea time slot, viewers on the west coast of America will be watching the episode at lunchtime, whilst those on the east coast of Australia will have to forego their Sunday morning lie-in and get up early. Although it is unknown how many of these countries will broadcast the special in 3D, a number of cinemas around Britain will also be showing the 90 minute episode to increase the number of fans able to watch the Doctor(s) in this format. As well as a way of BBC worldwide saying thank you to all the TV stations and viewers worldwide, the simulcast is also being done to reduce the level of spoilers and illegal downloads the show would otherwise produce, given the speculation that has already been building, and its apparent game changing nature. Although the internet was in its infancy when the 1996 Doctor Who UK/US co-production was broadcast a week earlier in the US than the BBC, fans annoyance at US network Starz broadcasting spin-off Torchwood: Miracle Day a week in advance led many British viewers to watch the 10 episode series online, reducing the audience figures for the BBC's television broadcast. Even more anticipated than this was however, the special will see current Doctor Matt Smith alongside previous Doctor David Tennant, as well as a mysterious incarnation of the Doctor played by veteran British actor John Hurt, although ninth Doctor Christopher Eccleston decided not take part. Joined by Jenna Coleman's Clara and Billie Piper's Rose, the episode will be broadcast (in most time-zones) on November 23rd, the 50th anniversary of the first ever episode An Unearthly Child.
