The "Crystal" Power of Veto was introduced in the final veto competition of "Big Brother 4" (2003). It could only be used by a nominee. If anyone else won it, it could not be used. The Golden Power of Veto is now the standard veto since season four. The fourth season also started the Big Brother Jury or sometimes called the "Jury of Seven". The Jury is made up of the final seven evicted HouseGuests. Each member of the Jury are isolated in a different house. The Jury members are not allowed to watch the show except for small parts such as the nominations and the Power of Veto ceremonies. They are not allowed to see any Diary Room interviews or any footage involving strategy or twists to the game. The Big Brother Jury votes to determine the winner of "Big Brother" each season.
