Earlier this year, we asked our readers to let us know what they believed to be the best sci-fi film of all time - and they certainly delivered, crowning Alien in the number 1 spot.

Now, we've returned to them, this time looking instead for the greatest sci-fi TV series of all time. Our post (via Facebook) has almost 1000 comments, with fans weighing in with the best of the best from the genre on the small screen.

Of course, sci-fi is extremely varied, and that has certainly shown up in the results, which we have sifted through to find the 10 most mentioned shows. The overall winner of the poll ended up being mentioned in almost one fifth of all comments.

Like our film poll before it, the results have seen no shows which began in the past decade show up in the top 10 - the most recent entry on the list began in 2015, while the oldest series started back in 1963 (if you're a sci-fi fan, you probably know which one that is...)

Without further ado, here is the definitive list of the greatest sci-fi TV series of all time according to Radio Times readers, counting down to the overall winner.
