Big Brother 15 is the fifthteenth season of the American reality television show, Big Brother. It began airing on CBS starting on June 26, 2013 on Sundays, Tuesdays and Wednesdays. It will continue to air on CBS until September 18, 2013. It is being called the "longest season to date" in Big Brother history, lasting a total of 90 days. This season features sixteen HouseGuests. 

The show's format remained the same from previous seasons of the show. A group of contestants, known as "HouseGuests", compete to win the series by voting each other off. They must be the last HouseGuest remaining. Each week, one HouseGuest, known as the Head of Household, must nominate two of their HouseGuests for eviction. The winner of the Power of Veto can remove one of the nominees from the block. The Head of Household must nominate another HouseGuest as a replacement. The HouseGuests then vote to evict one of them, the nominee with the most votes are removed from the show. When only two HouseGuests remain, the last seven evicted HouseGuests, known as the Jury of Seven, would decide which of them would win the $500,000 prize. A HouseGuest can be expelled from the show for not following rules.

There have been several controversial remarks from some of the Big Brother 15 HouseGuests. Their comments have angered viewers and because of this, the show's ratings have dropped. Many journalist have made negative reviews about the HouseGuests who made these remarks. HouseGuest including Aaryn Gries, GinaMarie Zimmerman and Spencer Clawson have made racist comments about two African American contestants on the show. Spencer made negative comments about a gay contestant calling him "Kermit the Fag". Aaryn and GinaMarie also made negative comments about Asian contestant Helen. Aaryn and GinaMarie were fired from their jobs because of their comments. However, they did not know about this until after the show because they were not allowed to be in contact with anyone outside of the Big Brother house. The show had to even put disclaimers before the episodes started to inform viewers that the comments made by houseguests were not the opinions of CBS.

Voting history

Notes

: For the first three weeks, viewers voted for which HouseGuest they believed to be playing the best game. This HouseGuest is named the Most Valuable Player, or M.V.P., and has the power to nominate one HouseGuest for eviction. This nomination is made privately and the HouseGuest is not obligated to reveal their identity. If the veto is used to save the M.V.P.-nominated HouseGuest, the M.V.P. also privately nominates the replacement. Their nominations are shown in bold.
:  For weeks four through six, America was given the M.V.P. power. The HouseGuest with the most viewer votes, other than the HoH and their two nominees, became the third nominee.  If the veto is used to take the original M.V.P. nominee off the block, then the next eligible HouseGuest with the highest amount of viewer votes will be nominated in their place. The nominations are shown in bold.
: Week 6 was a double eviction week. Following the first eviction, the remaining HouseGuests played a week's worth of game – including HoH and Veto competitions, and Nomination, Veto, and Eviction ceremonies – during the remainder of the live show, culminating in a second eviction for the week.
: After the normal Week 6 eviction, the M.V.P. power was removed from the game. All nominations after Week 6, including that week's second eviction, only have two HouseGuests nominated for eviction.
: During the Head of Household competition in Week 9, the first four jurors were allowed to compete for an opportunity to come back into the game. The juror who lasted the longest would return to the game to win and was eligible to become Head of Household if that juror finished first amongst the other HouseGuests in the competition.
