A four CD set encompassing music from all eleven Doctors' shows, including many pieces that have never before been released, is an incredible journey through the 5 decades of Doctor Who, with tracks from composers such as Ron Grainer, Delia Derbyshire, Dudley Simpson, Paddy Kingsland and Mark Ayres right through to Murray Gold. The tracklisting and release date will be announced shortly.

In addition, this year marks such a momentous anniversary for the series, Silva Screen will be releasing an 11 CD set, one for each Doctor, all presented in a specially created Tardis. This highly collectable box set is completely unique and strictly limited.

Significant accounting issues and the consequent working capital requirements at AudioGO led to it being insolvent. Unfortunately, there was no other option at this stage but to place the remaining UK business into administration, as no suitable buyer could be found. The administrators are taking all necessary steps to mitigate losses to customers and to maximise recoveries for the benefit of creditors.

We’re very pleased to announce that today is the day we’re beginning the release of our 50th anniversary Doctor Who story The Light at the End. We’re beginning with the Limited Edition CD box set.

It's the 23rd of October, one month ahead of the anniversary of Doctor Who on the 23rd of November, and as of today, the digital download releases for all versions of Doctor Who: The Light at the End will be made available. This includes the Limited Edition, the Standard Edition and the Vinyl Edition.

Mailing out of the Limited Edition CD version has begun today.

Nick Briggs, executive producer: ‘The Standard Edition CDs should start to be mailed out this coming Friday, and the Vinyl Edition will start mailing on November 2nd.

‘With the anniversary of Doctor Who imminent,’ continues Nick, ‘and everyone champing at the bit for the celebrations to begin, we thought it only right and proper that our special anniversary full-cast audio should be released a tiny bit early. Our plans for this very nearly went awry when the company responsible for the physical production of our CDs (and LPs!), Key Productions, experienced a series of unforeseeable problems beyond their control. This is what has caused the slight delay on the Standard Edition and the slightly longer delay of the Vinyl Edition. But for all our customers who can access the digital versions of all these releases, they can listen straight away.

‘We know that those customers who favour listening to the CD or the LP rather than downloading a digital version, might find this a little frustrating, but we thought this course of action would benefit the vast majority of our loyal listeners. We offer our sincerest apologies to any customers who find this decision doesn’t suit them, and hope they will understand our reasons for going ahead with the releases now.’

So, for Big Finish Productions, the 50th anniversary has started early. And for any of you who haven't yet ordered your copy of Doctor Who: The Light at the End, it will be on sale at the Dimensions 2013 convention (all tickets now sold) in Newcastle-upon-Tyne, where the Fifth, Sixth, Seventh and Eighth Doctors (Peter Davison, Colin Baker, Sylvester McCoy and Paul McGann) will be making guest appearances.

As you may have seen, the BF Website is back up and running again. But we would ask that if you can possibly wait a few hours to download The Light at the End, please do. The problem we have discovered is that although we have ample bandwidth to support the download of the quantity of data needed (loads of downloads of The Light at the End) another issue has emerged. The problem is being caused by the sheer number of customers visiting the site at the same time. We have to confess that this is the unforeseen circumstance we simply didn't anticipate. It is because the demand is so unprecedentedly huge that we didn't know to check this before releasing. The analogy that's been used to explain this to us is that it's a bit like having one shop assistant and thousands of customers all arriving at once. Our IT people will continuing monitoring the site and will make all efforts to correct any hold-ups as the hours pass. But, as we said, if you can possibly manage to wait to initiate your download, we would very much appreciate your patience. Huge apologies from all of us here at Big Finish.

Terry Nation - The Man Who Invented The Daleks
The Biography
Written by Alwyn W. Turner
Narrated by David Troughton

The Daleks are one of the most iconic and fearsome creations in television history. Since their first appearance in 1963, they have simultaneously fascinated and terrified generations of children, their instant success ensuring, and sometimes eclipsing, that of Doctor Who.

They sprang from the imagination of Terry Nation, a failed stand-up comic who became one of the most prolific writers for television that Britain has ever produced. Survivors, his vision of a post-apocalyptic England, so haunted audiences in the Seventies that the BBC revived it over thirty years on, and Blake’s 7, constantly rumoured for return, endures as a cult sci-fi classic. But it is for his genocidal pepperpots that Nation is most often remembered, and on the 50th anniversary of their creation they continue to top the Saturday-night ratings.

Yet while the Daleks brought him notoriety and riches, Nation played a much wider role in British broadcasting’s golden age. He wrote for Spike Milligan, Frankie Howerd and an increasingly troubled Tony Hancock, and as one of the key figures behind the adventure series of the Sixties – including The Avengers, The Saint and The Persuaders! – he turned the pulp classics of his boyhood into a major British export.

In The Man Who Invented the Daleks, acclaimed cultural historian Alwyn W. Turner, explores the curious and contested origins of Doctor Who's greatest villains, and sheds light on a strange world of ambitious young writers, producers and performers without whom British culture today would look very different.
