The Power of Veto competition (POV) is on of the 2 main contest on Big Brother, the other being the Head of Household competition. The winner of the POV is able to remove one of the HOH’s nominations. This forces the HOH to nominate another house guest for eviction. The house guest who wins the Power of Veto and uses it to save another nominated house guest cannot themselves be nominated for eviction. These competitions are usually played on a Saturday and tend to be more physical in nature. Like the HOH competitions CBS uses similar contests for POV every season and only changes the themes. During double eviction the POV is played during the live show. During the final 4 the POV winner gets to decide which house guest is evicted. The competitions are viewable in the Video Archive and are tagged POV for easy viewing.
The Veto Competition is held Saturday afternoon, usually once a year there is a night time POV that occurs Saturday night. The POV Ceremony is held Monday afternoon.
