23 November always holds a large significance for science fiction fans; it's the anniversary of the airing of the first episode of Doctor Who.
I'm still amazed today at how big the show still is; especially as I became a fan during the hiatus years. The stars of the show are among the most recognisable people in the UK and a show that was once only remembered for wobbly sets is now loved by millions.
The five years since the revival have seen the show grow from strength to strength.
Long may it continue.
