Ashley's Big Brother 9

Big Brother 9, also known as Ashley's Big Brother 9 and Big Brother 9: Back to Basics, is the ninth season of Ashley's Big Brother, which began at the beginning of the new year on January 1, 2015, ending exactly a month later on February 1. Fourteen housemates entered the house on launch night, with Samuel S. emerging as the winner on finale night.

Production
Big Brother 3 winner and All-Star housemate Janelle Pierzina hosted the show from this season onwards, joining veteran host Ashley Rivera. For the first time since Big Brother 1, there were no twists to the Big Brother format. It is also the first season not to include the Hidden Immunity Necklace, which was confirmed to have been discontinued before the season began.

Format
Each week lasts four days and comprises of four different events: the House Captain competition, nominations, the Power of Veto competition and an eviction of a housemate at the end of the week. The House Captain competition takes place on the second day of the week and decides which housemate would be in power for that week. This housemate is given immediate immunity from eviction for the week, and holds the responsibility of nominating one other housemate for eviction. The housemates begin nominating soon after the competition has finished; they are given 22 hours to visit the Diary Room and nominate two other housemates for eviction, and the two or more housemates who receive the most nominations face eviction alongside the Captain's nomination. Following the nominations reveal, the housemates compete in the Power of Veto competition, which allows the winning housemate to save one of the nominated housemates for eviction and replace them with someone of their own choice, or choose not to use it at all. Following the announcement of the final nominees, a poll opens in which the public decide which housemate should be evicted. The eviction take place on the final day of the week, and the cycle continues.
