Steven Moffat is the lead writer and showrunner of Doctor Who and Sherlock, the hit modern take on Sir Arthur Conan Doyle's supersleuth which will film its third series next year. Doctor Who recently returned to BBC1 with plenty of plaudits (and Daleks and dinosaurs), and next year promises to be even bigger, marking the time-traveller's 50th anniversary.
Moffat is married to successful TV producer Sue Vertue who is the daughter of another, Hartswood Films founder Beryl Vertue.
He has poured cold water on the idea of a Doctor Who film any time soon – but who can resist the prospect of a big-screen Doctor? Don't try to coax him on Twitter, however; he quit the social network earlier this month. Busy times.
BBC executives that have an influence on Doctor Who's future in the list include the new Director General George Entwistle in fourth place (last year 26), and BBC1 Controller Danny Cohen at number 13 (last year 14).
The Media 100 has been compiled every year since 2001 by the Guardian, and is a list of who they consider are currently the most powerful people in the UK media. Candidates for the list are judged on cultural influence, economic clout and political power over the course of the last year.
