Meta-fiction universe

The Doctor and Izzy Sinclair visited a variant on the years 1979 in which the Doctor's reality existed only as fiction. There, at BBC Television Centre, the actor Tom Baker fended off Beep the Meep by infuriating him with his endless rambling. The Doctor realized the truth when he found himself with the first issue of Doctor Who Weekly. (DWM: TV Action!)

Other information

 * In another timeline, television writer Martin Bannister had not managed to make the television series Doctor Who a success. (DWU: Deadline)
 * Yet another timeline, the Bureau of Time Travel permitted the use of time travel as a means to correct several production mistakes made in that series. Time paradoxes caused the series not to succeed and the Bureau of Time Travel itself never to have existed. This created a timeline similar to Martin Bannister's. (ST: All Our Christmases)
