Secret History - Season 17
7.00 48 minutes Secret History was a long-running British television documentary series. Shown on Channel 4, the Secret History brandname was used as a banner title in the UK, but many of the individual documentaries can still be found on US cable channels without the branding. It can be seen as Channel 4's answer to the BBC's Timewatch.
