Hello! It is no1drwhofan, here.
As I am sure আপনি are aware. 'Doctor Who' has been running for almost 49 years. Furthermore, I think we can all agree that it is a very quintessential part of any Whovian's life, anywhere and everywhere.
However, there have been arising speculations over the last two years, resulting in my apprehension about the show's future increase with every passing hour.
Moreover, the below sources should hopefully engage your understanding of my worries about the show:

Assuming আপনি have read/skimmed through the above articles, I hope my concern for the show's ratings are আরো coherent to you. Nonetheless, I don't think anything অথবা anyone can articulate greatly I fear for the show's future.
But be that as it may, all I can do is enhance my optimism to the fullest possible degree, in the hope this will keep 'Doctor Who' running.

Until the পরবর্তি time! Xxxxxx

Note: the ratings প্রদত্ত in the captions of the pictures are not accounting for the বড়দিন specials in the series; only the 13 episodes in each series. Of course the প্রদর্শনী has high ratings at Christmas!!!! :)
Nonetheless, I will write them here instead, so we can see if there is a negative/positive correlation from 2005 to this very juncture:

2005 'The বড়দিন Invasion' (Tennant): 9.8 million.

2006 'The Runaway Bride' (Tennant): 9.4 million.

2007 'Voyage of the Damned' (Tennant): 13.31 million.

2008 'The পরবর্তি Doctor' (Tennant): 13.1 million.

2009/10 'The End of Time' (Tennant): 12.04 and 12.27 million.

2010 'A বড়দিন Carol' (Smith): 12.11 million.

Hmm...taking the above statistics into consideration, one may conclude that the বড়দিন ratings have gone down slightly. However, are higher than 2005/06. Nevertheless, পাঠ করা the captions under each picture may suggest otherwise about the series in general.
