First, Sunday has a bigger television audience. Second, while losing ratings from a big opening is normal, it's still losing them, very consistently. And this isn't just live ratings, where a drop being this hard would make sense. This is with iPlayer, DVR, etc.
For 2018, and for the first time, the BBC have now started to register viewings on tablets, something the previous years had not. So that's a nice boost to the latest viewing figures.
Even Eccleston's and Tennant's Doctor didn't have the privilege of iPlayer hits back in their day.
Viewing figures are up from last year due to it being shown on a Sunday. Sunday has been Series 11's success story.
If this series was still on a Saturday it would be getting the same figures as previous series, perhaps even fewer, which is why it is unfair to compare the two days as they are entirely different animals in viewing habit terms.
Not to mention weaker opposition on a Sunday, that people watch more television on a Sunday, a fixed schedule, between two extremely popular Top Ten BBC shows, etc. That is not nothing.
Sunday has been the shows 'success' in ratings.
Losing ratings from a big opening is normal but it's still losing them, very consistently. And this isn't just live ratings, where a drop being this hard would make sense. This is with iPlayer, DVR, tablets, etc.
To say it is averaging higher then Tennant's third season is a really bad argument, that makes no logic sense. Take out the first episode of the new season, which had the new Doctor hook, and see the average at the end of the season. Heck if he ratings keep on falling like this, even with only 10 episodes and the new era bounce episode, it is going to slip well behind. On a Sunday. Which has a the biggest audience share of the week.
3.24 million drop from episode 1 to 5 has been the fastest drop in the show's history.
Compared to Series 10, from ep.1 to 5, it had dropped 1.4 million.
