I have recordings of the BBC series "Tomorrow's Worlds: The Unearthly History of Science Fiction" and it appears that "The Real History of Science Fiction" is a different show, edited for the US from the same material as the BBC version. The amazon versions have a 43 minute runtime, while the original BBC versions have a 59 minute runtime. See the two different listings below. https://www.amazon.com/Real-History-Science-Fiction-Season/dp/B00JTKJS3M https://www.bbc.co.uk/programmes/p01yqk7d

I'll go ahead and remove the alternate title to prevent further confusion.
