Announced Friday over an official tweet, was that Doctor Who showrunner, Steven Moffat, will be stepping down after the conclusion of series 10.

Moffat became showrunner (credited as executive producer) after replacing Russel T. Davies, who in 2005, led the franchise to be resurrected from its television hiatus.

Beginning with series 11 in 2018, the show will be helmed by Chris Chibnall, currently the showrunner of BBC show Broadchurch. “Feels odd to be talking about leaving when I’m just starting work on the scripts for season 10,” Moffat told the RadioTimes, “but the fact is my timey-wimey is running out. While Chris is doing his last run of Broadchurch, I’ll be finishing up on the best job in the universe and keeping the TARDIS warm for him.”

Chibnall offered his own opinion about taking over for Moffat: “it’s a privilege and a joy to be the next curator of this funny, scary and emotional family drama. I’ve loved Doctor Who since I was four years old, and I’m relishing the thought of working with the exceptional team at BBC Wales to create new characters, creatures and worlds for the Doctor to explore.”

Doctor Who airs on BBC One and BBC America. While collections of original episodes are available on Netflix, series 1 through 8 are currently available. Series 10, starring Peter Capaldi, debuts in Spring 2017.
