Doctor Who, Strictly Come Dancing and X Factor all saw big drops in their viewing figures for Sunday night.
An average audience of 6.4 million tuned in for the third episode of the new series of Doctor Who. While it was well up on the overnight figure for the equivalent episode of last season, it was down 600,000 on last Sunday.
The first of ten new episodes had launched last weekend to 8 million viewers, consolidating to more than 10 million. The BBC revealed last week it was the most watched Doctor Who launch since the 2005 revival.
After Doctor Who, Strictly Come Dancing was also down.
The latest results, which featured a performance from Paloma Faith, saw an average of 8.6 million viewers, 600,000 below last week's numbers.
As usual in the Strictly Come Dancing results, the judges' marks were combined with the viewer votes. Vick Hope Piper and her pro partner Graziano Di Prima found themselves in the bottom two with Seann Walsh and his partner Katya Jones.
They both reprised their latest dances before judges Shirley Ballas, Darcey Bussell, Craig Revel Horwood and guest judge Alfonso Ribeiro then had to decide who to save, with head judge Shirley having the casting vote.
Craig saved Vick but Alfonso, Darcey and Shirley all saved Seann, sending Vick home.
Over on ITV, The X Factor averaged 4 million for the first of its live results shows. This is down a million last Sunday's numbers and a series low. For a second week, there was an overlap with Strictly Come Dancing for 30 minutes.
Two acts were eliminated in the X Factor 2018 results as both Olatunji Yearwood and Armstrong Martins got the boot.
Olatunji was automatically sent home after polling the least public votes while Armstrong faced Janice Robinson in the sing-off after receiving the next fewest votes from viewers.
After Janice and Armstrong sang again, the judges decided who to save with Simon Cowell, Ayda Williams and Robbie Williams all sending home Armstrong. Louis Tomlinson stood by his act and sent home Janice.
Following The X Factor, new ITV drama Butterfly starring Anna Friel continued with 2.3 million viewers against 5.3 million for The Cry on BBC One in the same slot.
