Re: 50th Is "The Day Of The Doctor" (And Is 75 Minutes)
But if its simulcast, it will likely NOT have adverts.
I don't think it's ever simulcast in that sense. We've had BBC America show episodes on the same day the BBC debuted them, but not at the exact same time, due to the time-zone difference. Not only is the US several hours later, but Doctor Who
airs here as a prime-time show, whereas I think it's late afternoon/early evening in the UK.
Now this time as with the annoucement of Peter Capaldi as the next Doctor it supposed to be simulcast at the same time, so it'll be on at 3PM EST here.
The greatest science fiction series of all time is
Doctor Who! And I'll take you all on, one-by-one
or all in a bunch to back it up!"
