Official Ratings
The game has well and truly changed for Big Brother 2018 – but can the show rack up viewers like the housemates rack up Big Coins?
Below are the four-screen consolidated (a.k.a. ‘official’) viewing figures for the main show. In addition to viewers who watched on Channel 5+1, these include on-demand streaming data from My5 via its iOS, Android and web applications.
There are two tables, covering different periods: 7 Day ratings, which account for viewers who watched episodes up to one week after they were originally broadcast, and 28 Day ratings, which account for four weeks after original broadcast. Click the links to jump between tables.
Episode cells are colour-coded to indicate how the amount of viewers compares to the equivalent day from the previous regular series.
