Big Brother 17 (also known as Big Brother: Takeover) is the seventeenth season of the American reality television series Big Brother. The season premiered on June 24, 2015 with a two-night premiere with the following episode airing on June 25, 2015, broadcast on CBS in the United States and Global in Canada. The season ended with a 90-minute season finale on September 23, 2015, following the fall season premiere of Survivor: Cambodia, after 98 days of competition. Julie Chen returned as host. On September 23, 2015, Steve Moses was crowned the winner defeating Liz Nolan in a 6–3 jury vote. James Huling was voted as the season's America's Favorite HouseGuest.

Format Big Brother follows a group of contestants, known as HouseGuests, who live inside a custom-built house outfitted with cameras and microphones recording their every move 24 hours a day. The HouseGuests are sequestered with no contact with the outside world. During their stay, the HouseGuests share their thoughts on their day-to-day lives inside the house in a private room known as the Diary Room. Each week, the HouseGuests compete in competitions in order to win power and safety inside the house.

At the start of each week, the HouseGuests compete in a Head of Household (abbreviated as "HOH") competition. The winner of the HoH competition is immune from eviction and selects two HouseGuests to be nominated for eviction. As with the previous season, the first five weeks of the season feature two concurrent Heads of Household. Each HoH would nominate two HouseGuests for eviction, for a total of four nominees. The two pairs of nominees would then compete in a "Battle of the Block" competition. The winning pair would be removed from the block, with the HoH who nominated them dethroned. The dethroned HoH would later be eligible to be nominated as a replacement if the Veto is used, while the Battle of the Block winners are safe for the rest of the week.

Six HouseGuests are then selected to compete in the Power of Veto (abbreviated as "PoV") competition: the reigning HoH, the nominees, and three other HouseGuests chosen by random draw. The winner of the PoV competition has the right to either revoke the nomination of one of the nominated HouseGuests or leave them as is. If the veto winner uses this power, the HoH must immediately nominate another HouseGuest for eviction. The PoV winner is also immune from being named as the replacement nominee. The HouseGuest overthrown as a result of the Battle of the Block competition is eligible to be nominated by the reigning Head of Household if the Power of Veto is used.

On eviction night, all HouseGuests vote to evict one of the nominees, though the Head of Household and the nominees are not allowed to vote. This vote is conducted in the privacy of the Diary Room. In the event of a tie, the Head of Household casts the tie-breaking vote. The nominee with the most votes is evicted from the house. The last nine evicted HouseGuests comprise the Jury and are sequestered in a separate location following their eviction and ultimately decide the winner of the season. The Jury is only allowed to see the competitions and ceremonies that include all of the remaining HouseGuests; they are not shown any interviews or other footage that might include strategy or details regarding nominations. The viewing public is able to award an additional prize of by choosing "America's Favorite HouseGuest". All evicted HouseGuests are eligible to win this award except for those who either voluntarily leave or are forcibly removed.

Format changes and additions BB Takeover CBS announced the season's twist, BB Takeover, on June 17, 2015, in which a surprise guest would visit the house each week to reveal a different twist to the HouseGuests. Though it was initially announced that there would be a guest every week, there were no Takeovers after Week 3; in an interview during the season, Julie Chen stated that the twist had been cancelled because "there was enough going on” with the other elements of the game, though no official announcement was ever made to the HouseGuests.

Week Takeover guest Twist Effect 1Phil Keoghan Two additional HouseGuests The Amazing Race 26 alumni Jackie and Jeff entered the game. BB Fast Forward Immunity for the week was granted to the two HouseGuests who sat out of the first HoH competitions and one HouseGuest each of their choice. 2 Kathy Griffin Last Laugh The power to block three HouseGuests from voting in the next eviction was granted to the HouseGuest who answered the seventh call to a phone booth in the house. 3Rob Gronkowski Gronk Party Week Have-Nots were removed for the week, provided the HouseGuests participated in Gronk Parties throughout the week. Luxury competition All of the week's competition winners earned a chance to win a cabin on a three-day cruise.

Battle of the Block The Battle of the block was first introduced in the sixteenth season. In the twist, two houseguests would be nominated by each Head of Household. Each pair of HouseGuests would compete in a Battle of the Block competition. Whichever pair won would have safety for the week, and the Head of Household who nominated them would be dethroned, leaving one Head of Household remaining.

Twin Twist As with the fifth season, a pair of twins competed as one HouseGuest, switching every few days between the house and a sequestered location off-site. The twins, Liz and Julia, played as Liz, changing places in the Diary Room with approximately ten minutes to catch each other up. After the twins survived the first five evictions, the twist was revealed and both twins competed separately. Though the twist was not officially revealed to the other HouseGuests before its completion, the twins were allowed to discuss it freely.
