LOS ANGELES -- BIG BROTHER 6 will put the power back into the hands of the viewers on Thursday, Aug. 25 (8:00-9:00 PM, ET/PT) when host Julie Chen announces a second America's Choice vote on the reality series. Once the America's Choice question is announced, viewers will have the opportunity to cast their ballot on CBS.com or vote via text messaging on their mobile phones.
Votes via text messaging and CBS.com will be tabulated during a specified time window following the episode broadcast. Voters will then be informed of the outcome on the following installment of BIG BROTHER 6 to be broadcast Tuesday, Aug. 30 (9:00-10:00 PM, ET/PT) on the CBS Television Network. CBS will offer the text messaging option as well as downloadable wireless applications relating to BIG BROTHER 6, through a partnership with GoldPocket Wireless.
During the first America's Choice vote, more than five million viewers cast their ballots on CBS.com and over 500,000 text messages were received for one of the evicted houseguests to return to the BIG BROTHER 6 house. With an overwhelming 82 percent of the vote, Kaysar was voted back into the house. Unfortunately, Kaysar's return was short-lived when he was evicted by a majority of the houseguests the following week.
This week's America's Choice vote does not involve a house guest returning to the "Big Brother" House.
