Here are the weekly average Nielsen ratings:
week 1) 6.89
week 2) 5.64
week 3) 6.32
week 4) 6.90
week 5) 7.13
week 6) 7.80 (Chima expulsion)
week 7) 7.51
week 8) 7.95
week 9) 7.58
week 10) 7.26
As in the previous seasons, after week 1 viewership climbed steadily. This year, though, it only increased until week 6's Tuesday 8/18 Chima expulsion show. The immediate 9.3% drop on 8/20 was the largest Tuesday-Thursday drop in the show's history (after week 1). In the season's second half, as in most previous years, non-core viewers return only for eviction shows, so production is smart to pack in extra evictions late in the season. But even so, weeks 9 and 10 don't rise above Chima expulsion week 6's peak. Compared to week 6, except for a small upward blip of 1.9% at week 8, each week is substantially lower than week 6: week 7 is 3.7% lower, week 9 is 2.8% lower, and week 10 is 6.9% lower. As the producers know, the show does best when it can maintain the presence of an Evel Dick. America's Choice-type houseguests make for low ratings.
Here's the raw data. Tuesday evictions have an asterisk.
