All Our Christmases seems to be a story of interest here. The meta-fiction universe page seems to assert that the Deadline universe is really an alternate timeline to our universe. So in the future of our universe, Richard goes back in time, affects the history of Doctor Who, and ultimately his changes mean that the programme never took off at all. (I think it cites the implied Juliet Bravo connection to piece it all together.)

Even so, if we cannot be certain that TV Action! and TGWLD share the same universe, then this applies to an alternate timeline in Deadline and All Our Christmases too.
