Gibbons was replaced by Mick Austin (70-84), who was better known as an illustrator for "real" magazines. I later twisted Mick's arm into producing some of the best 2000AD covers ever and we even worked together on a Judge Dredd strip I consider one of my best, "The Manchu Candidate" (2000AD, progs 881-883). Mick gave way to Steve Dillon (86-87), later to be artist on Preacher, before John Ridgway contributed his mammoth four year run on the title (88-132), though I would leave before Ridgway did. John and I would work together again on Luke Kirby for 2000AD (progs 571-577 & 800-812).
Sadly, the back-up strips, which had explored aspects of the Doctor Who universe other than the Doctor himself, had been discontinued back in Doctor Who Monthly 59, except for a one-off Freefall Warriors in issue 84. This was mainly for budgetary reasons,although the magazine was selling pretty well, and I felt it was a great loss as it badly affected the balance of the magazine.

The other vital component of the magazine was the feature material.
At that time we had free access the the BBC picture library, and the entire run of the Doctor Who show had been carefully documented by the staff BBC stills photographers. So pictures weren't a problem.
However, finding an endless supply of text material was a tall order. The Weekly version of the magazine had forged a connection with the Doctor Who Appreciation Society, so it seemed natural to turn there for text features.
So the Society would supply text material like episode guides, story synopses and interviews then I would have to re-work the material into a style acceptable for a professional magazine. I'd then return the edited copy to the Society to have them check I hadn't edited in factual errors. The copy would then go to the Doctor Who production office to be checked by the then-producer of the show, John Nathan-Turner.
