The Jury was introduced in Big Brother 2 (US). The final seven evicted houseguests, not including the Final 2, are members of The Jury. They vote for the winner of Big Brother. Up until Big Brother 4 (US), all the evicted houseguests voted for the winner of Big Brother. The Jury became only the final seven evicted houseguests because, in Big Brother 3, Danielle Reyes lost the season because of her Diary Room confessions. Thus, The Jury and the Sequester House were born. From Big Brother 15 (US) onwards, the jury has consisted of nine houseguests. Big Brother: Over The Top had no jury, being the first season since its introduction in BB2 to not feature a jury. Celebrity Big Brother 1 (US) returned to the original jury format, where all evicted houseguests were jurors, and instead of being sequestered, they went back home and returned on finale night.
The Jury House
As of Big Brother 4 (US), each member of the Jury lives the remainder of the Big Brother game in total seclusion, arriving in an undisclosed location, usually a tropical and beautiful house. They have access to movies and games, a pool, and (depending on the location) a private beach. They are not allowed communication with the outside world so that their votes are not tainted by behind-the-scenes information, such as secret alliances or betrayals that they may not be aware of.
The Jury stays privy to house happenings in the form of a DVD brought along with the most recent evicted houseguest, showcasing competitions and other group activities. Secret meetings, Diary Room sessions, and other happenings that do not include the entire group of remaining houseguests are not disclosed.
In Big Brother Canada 1, Big Brother 15 (US) - Big Brother 18 (US), and Big Brother 20, the jury members got a chance to return to the game. Big Brother Canada had a public vote, while the U.S. seasons had a competition.
On finale night, each juror casts a vote for whom they would like to see be the winner of Big Brother. Each vote is one of the names of the Final 2 written on a key (or a chip for BBCan), which the juror places in the nomination box. In the same format as a Nomination Ceremony, the keys are removed one at a time, revealing the winner of the season.
