Big Brother 17 (also known as Big Brother: Takeover) premiered on CBS on June 24, 2015, and concluded after 98 days of competition on September 23, 2015, with Julie Chen returning as host. The season featured a recurring "Battle of the Block" twist, where two Heads of Household each nominated two HouseGuests, allowing the winning pair to dethrone their HoH. It also introduced the "BB Takeover" gimmick, which was meant to bring a surprise guest each week to reveal new twists—though this was cancelled after just three weeks. In the end, Steve Moses emerged victorious, defeating Liz Nolan in a 6–3 jury vote, while James Huling won the public's vote for America's Favorite HouseGuest and a $25,000 prize. The finale aired alongside the premiere of Survivor: Cambodia, making for a dramatic night of reality TV.
