The Bletchley Circle cancelled

ITV has cancelled its 1950s codebreakers drama, Bletchley Circle...

We may not have covered The Bletchley Circle on this site, but any show whose official Twitter handle is @ladynerds surely falls under the protection of our geek umbrella.

After two short seasons, ITV's women-led 1950s-set codebreakers drama has been cancelled. The series starred Anna Maxwell Martin, Rachel Stirling, Sophie Rundle and Julie Graham as former WWII Bletchley Park codebreakers, using their considerable nous in post-war civilian life to solve crimes.

A four-episode second series of the drama ran earlier this year, and despite it hanging on to an average of 4.9 million viewers each week, ITV appears to have called time on the female investigators. The Twitter response to the cancellation has been characterised by disappointment, with messages displaying quite understandable "There are obviously already too many women geniuses being awesome on TV" frustration.

Anyone who followed the Ripper Street developments from the news of cancellation to its phoenix-like return knows that the end isn't necessarily the end these days on television. As we discovered here, fan campaigns can shore up and offer moral support to executives fighting for renewal. Watch this space...
