Last Christmas

It’s been 52 years since the BBC first introduced Doctor Who. Yet even after all those decades and cast changes, the most recent season of the sci-fi classic was the most popular yet among U.S. viewers. BBC America announced Doctor Who finished the year marking its highest ratings ever, averaging 2.3 million viewers for the season.

Plus the show’s Christmas Day special, which had the Doctor teaming with Santa, had 2.6 million viewers across two airings.

The viewerships helps affirm Peter Capaldi, who took over the show’s starring role this season, along with co-star Jenna Coleman. Doctor Who will return with a new season this year.
