The BBC can sometimes create some amazing content, only the blockbuster stuff like this, Dr Who and some other stuff gets marketed outside the UK. There are some seriously excellent radio programmes that go into some great depth into subjects and connect to some of the best minds in the field. For those who digest info by audio book, there are some amazing resources like "In Our Time" and "The Life Scientific" that can't be found anywhere else.
