For the masses of one time pad fans in the UK, there's a documentary about the Venona Project tonight. See this wiki article for some background, and would be useful for all those nay sayers that insist one time pads are useless ;-)
This is probably only the second documentary type on encryption I've seen. They're usually about Bletchley's efforts regarding Enigma. It's on Yesterday channel, 5 Feb 2016, 2200hrs (GMT), called "Secrets, Lies and Atomic Spies"
