The Big Brother Final was watched by a peak audience of 5.1m on Friday night, with 23% audience share just after 10:15pm as Rachel was announced the winner of BB9. The return of popular chat show host Jonathan Ross on BBC1 at 10:35pm, may have contributed to the decline of BB9. Between 10pm and 11.05pm, Big Brother averaged 4.7 million viewers, yet was down 600,000 on last years peak final (5.7m).
The first eviction show between 8 and 9pm had 3.9m viewing figures as Darnell, Rex and Sara all found out they had lost out on the Big Brother £100,000 prize. Channel 4 had a 17% audience share as the programme had to compete with Eastenders on BBC1.
A further 376,000 and 166,000 viewers, respectively, watched Friday's two Big Brother instalments an hour later on the digital service Channel 4 +1.
The Guardian reports, "Big Brother's ratings have been in steady decline since series seven in 2006, when the two final-night shows attracted 6.3 million and a 29% share, and 7.7 million and 39%, respectively.
The show's ratings high-point was series three in 2002, when Kate Lawler's victory attracted an average of 9.4 million viewers to the 10pm final night show – a 50% share."
