Let's not look at his career in a linear fashion, for as any Whovian can tell you, Moffat, born in Scotland in 1961, loves nothing more than to tamper with the forces of chronology. Moffat's stories for the revived sci-fi series have been consistently phenomenal.
He took The Doctor and Rose back to the Blitz in 'The Empty Child', reviving the scary potency of the gas mask and coining the eerie phrase 'Are you my Mummy?' in the process. The introduction of the suave con/Time Agent Captain Jack from the 51st Century (just like Magnus Greel) saw a clash between future hi-tech and past archaic technology.
The legendary Sally Sparrow had to prize out clues left by The Doctor from back in 1969, before bumping into the time traveller in temporal paradoxical fashion - as he had yet to meet her! Plus, Moffat penned the touching 'Time Crash' sketch for Children In Need, as two Doctors past and present came face to face in the Tardis.
Moffat has won this last category, voted for by the members of the World Science Fiction Convention, in both 2006 for 'The Empty Child' and 2007 for 'The Girl In The Fireplace'. His mantelpiece must be creaking more than the limbs of a rusty Cyberman!
Let's step back in time, to quote the lady behind Astrid Peth. For Moffat was the man behind the recent BBC reboot of Jekyll, which starred James Nesbitt, and the warmly-received sitcom Coupling. Both shows, despite their wildly differing genres, liked to toy around with time and structure to add layer upon layer of depth and intrigue to the proceedings.
Moffat, who possesses an English degree, first soared to prominence in 1989 by writing the much-loved ITV youth drama Press Gang. The programme revolved around a newspaper established by the pupils of a comprehensive school and lasted for five seasons, was bombarded with praise, scooped a BAFTA and propelled Julia Sawahla to stardom. The show also put Dexter Fletcher on the map, but all is forgiven.
More comedy followed in the shape of the acclaimed Joking Apart, but the critics brutally yanked down Moffat from his pedestal when his 1997 school-based sitcom Chalk hit the box. Nonetheless, the series did introduce fictional porn film 'Lesbian Spank Inferno' in the cultural consciousness - so much so that Coupling even made reference to it.
In the more immediate future, we have a new two-parter to devour in the shape of 'The Silence In The Library' and 'Forest Of The Dead'. Boasting star turns from Colin Salmon and Alex Kingston, the story is set to do for shadows what 'Blink' did for statues.
Let's leave the current 'Big Cheese' Russell T. Davies to have the final word on his successor. Speaking at a recent Broadcast conference in London about his work on the show, Davies said: "I'll rewrite 100% if I have to. With Steven Moffat's scripts, I don't touch a word, but anyone else's I do..."
