Not sure if this is a glimpse of things to come for the US version of Big Brother or not.
[I]n its tenth year, Channel 4’s “Big Brother” appears to be running out of steam, with U.K. ratings falling to their lowest level since the show began. […]
This year, however, almost two months into its three-month the U.K. show is averaging 2 million viewers and a 10.1% audience share, around 33% down on its performance last year and well down on earlier series, some of which averaged audiences of almost 6 million viewers per episode.
In the key 18(or perhaps 16)-34 advertising demographic the show earned 700,000 viewers and a 16.7% audience share this year.
The show debuted this year with 4.8 million viewers and a 22.1% share, down from 5.2 million last year and a 24.2% share a year ago.
