Doctor Who Might Have Ended in 2010

Speaking at the Hay Festival recently, Steven Moffat said there was a strong possibility that Doctor Who could have ended after David Tennant's run

David owned that role in a spectacular way, gave it an all-new cheeky sexy performance and became a national treasure. And he didn’t do it instantly, he did it over time. So the idea that Doctor Who could go on at all in the absence of David was a huge question. I didn’t realize how many people thought it wouldn’t succeed at all. That was quite terrifying when I found out about it later. I think there were plans maybe to consider ending it. It was Russell T Davies saying, you are not allowed to end it.
