Broadcast is coming to an end in many countries. So where can you see the films now?
If you've missed a film or want to see it again, check out your local broadcaster's online on-demand service to see if it's available on their website.
Most broadcasters will keep the whole series up for a week or fortnight after the last programme broadcasts.
You also try and catch the films on BBC World who are broadcasting through the month, here's their schedule.
We'll have all the films online in early January. You'll be able to see full length versions of all 8 documentaries wherever you are in the world for free. But we have to wait for the main broadcast period to finish before we can make them available.
We'll also look at putting them on DVD and we'll have a whole range of educational resources around each film - but that will take time!
There is still a huge audience we want to reach. So please come back and see us in the New Year. If you sign-up for our newsletter, follow us on Twitter or like us on Facebook we can let you know when the films are available.
