I heard about this program about a history of atheism. It has been aired on a few PBS stations around the country but not very many.
The program is called 'A Brief History of Disbelief' and is produced by a British production company. I have emailed my local PBS affiliate asking that this program be aired. It is a very well done discussion of atheism. I would like to see if more widely aired. You can watch it here in 3 parts:
A Brief History of Disbelief - Part 1
If you would also like to see this program aired on your local PBS station, please send them an email!
