Doctor Who 02

The Doctor’s latest incarnation delivered the sci-fi cult-fav’s biggest U.S. premiere audience yet.

BBC America’s Doctor Who returned to 2.6 million viewers when including its first two replays—a record-setting opener for the series. The debut airing of season eight’s “Deep Breath” featured star Peter Capaldi’s first full episode as the Doctor. During its 8 to 10 p.m. premiere Saturday night, Doctor Who was the most-watched show on cable and dominated Twitter for the day among TV shows. The numbers are despite the episode leaking online weeks in advance.

Still, the performance is modest compared to the show’s U.K. audience, which posted 6.8 million viewers on BBC One, the show’s biggest premiere delivery since 2010. It’s also lower than the “Day of the Doctor” special, which had 3.6 million last year.
