I think this was a Christmas Special but just checked the website and it's still active.
Chronicle is a history-themed SVOD with apps on all the various smart TV / mobile phone / OTT devices. The blurb from their website's about section reads:
Chronicle is a place that understands, welcomes and celebrates the love of history. We are a community of history lovers, documentarians, authors and experts. Those who want to respond, to be involved, for those who are more than “interested”.
The love of history is powered by an appetite to know and understand. The love of history is restless and challenging.
Which is why the lover of history can never be content with a single book or documentary on a subject, or feel that their knowledge is complete.
Chronicle is for those who love this stuff.
