I'm sorry but what does that say for the great British Tv watcher. Thinking soaps are real is silly but to actually think you could do this takes the biscuit.
The law of averages says that for every million people watching, a proportion will have difficulty in separating reality from fantasy.
It's gone on since people used to contact the West Midlands Tourist Infomration looking to book into Crossroads, and I am sure a number of people call the number on the taxis in Corrie which - if memory serves - is the old Granada Studios switchbaord number.
I can wrap my head round the possiblity of people confusing soaps with reality, but we're talking Time machines and time lords and space and monsters that are purely the realm of nightmares.
To think that this fictional person will answer is just a tad beyond belief.
Maye a few might have been doing it for a joke but over 2500 people.
The mind it doth boggle.
In a similar vein, Hollywood has been using fake numbers for decades. The majority of US film and tv shows use the 555 prefix as that number is not used in the USA. More info here.
I suppose there are many people who will dial a number just to hear what or who is on the other end. The Beeb missed a trick as they could have put a message on from the timelord himself.
