Gran Hermano (Argentine season 9)

On Launch Night, host Jorge Rial revealed that all housemates that moved in on Day 1 (18 May 2016) were not definitive contestants for the series, and the audience would decide who the final contestants would be. The twist was revealed during the debut gala of this series. According to what the host said, this how the mechanism will work to select the final set of contestants: the public will choose one male and one female housemate to become "The Protgées", then one housemate will be sent home by Gran Hermano and the other one by host Jorge Rial, more details will be revealed during the course of the first week of the housemates in the house.

On Day 8 (25 May 2016), it was announced that a Triple Eviction would take place: Two evictees by Gran Hermano and one by host Jorge Rial. Before the evictions happened, Azul & Mauricio were announced as the two most voted contestants by the public, therefore becoming "The Protegées". Mariano was the first housemate evicted, chosen by Gran Hermano, the main reason behind his eviction was because he was not feeling comfortable inside the house with the rest of his fellow castmates. Carolina soon followed and was also chosen by Gran Hermano to be evicted on Day 8. After this violent behavior during the first week, Jorge decided to evict Lucas, and he became the third housemate evicted on Day 8.

On Day 22 (8 June 2016), Macarena decides to quit the game. In the following days an open vote between the previously evicted females from this series (Carolina & Yasmila) together with several contenders from Gran Hermano 2015 (Belén, Florencia, María Paz, Marian & Valeria) was made. On Day 29 (15 June 2016), the most voted from each group would enter the game to compete to become Macarena's replacement, the ones who entered were Yasmila & Marian. However, on Day 32 (18 June 2016), during the evening, in a way of a prank mixed with some yelling that happened earlier that day, Marian together and motivated by Dante briefly escaped the house through the backyard.[10] On Day 36 (22 June 2016), a decision on their case was made, with host Jorge Rial announcing the results inside the house together with all housemates remaining. They were ultimately ejected for trespassing the rules and breaking the isolation the way they did. Because of producers extending the announcement of their decision, the vote-to-evict that began on Day 29 was extended through Day 43 (29 June 2016).[11]

Azul decided to quit the game during the evening of Day 38 (24 June 2016), however, her exit was confirmed hours later. The reason behind her decision was an argument between Ivana and the rest of the remaining male housemates occurred that night,[12] because of its intensity, it became Azul's tipping point and convinced her to quit the game, as confirmed the following day by Rial.[13][14][15][16] The next day, Rial in a Periscope chat with his followers, explained that indeed, Azul left the house unnoticed and Azul, she received immediate attentions by producers and the show's psychologists. He also stated that Azul was fed up with all the arguments and fights that happened so far into the season and she could not take them any longer.[17] In the following live show, on Day 43 (29 June 2016), Azul re-entered the House to explain herself to her fellow housemates exactly what led her to leave, as mentioned previously, on that evening - Day 38 - because of the intense fight that occurred during while the majority of the housemates were having dinner, the yelling and intensity of that argument became unbearable for her, and that's why she walked all the way to the backyard, and just as Dante & Marian did the previous week, she climbed the wall and jumped outside the house.

On Day 50 (6 July 2016), 4 new potential housemates entered the house: Ainelén, Antonella R., Bárbara & Valentina, and their mission was to be themselves and impress the show's producers and Gran Hermano so they could stay and become the new official housemates. After one week inside, Ainelén & Bárbara became the new housemates, and the other 2 candidates left the house that very same night.

During Week 11, a special repechage vote was announced and was between several of this season's evicted housemates. The housemates up for public vote in this special voting round were: Agustín, Antonella P., Belén, Luifa, Julieta, Macarena & Matías S., the public was given just a few hours to cast their votes, Luifa became the lucky housemate to return to the game, and he received 70,6% of all votes cast. This special vote left many fans disappointed as they didn't expect it to happen and the outcome made the whole ordeal even worst, as many expressed on social media that it was set so Luifa (who was evicted just the week before) was given an undeserved second chance. Also, one of the most shocking details of this repechage was that twin sisters Antonella & Julieta Pozzi, who played the game as a single entity, were split for this repechage.

A total of 19 housemates entered on Day 1 (18 May 2016).[18] It was clarified during the Launch show, that sisters Antonella & Julieta Pozzi will play as a single housemate. Several of the housemates are linked to local celebrities, either because they're relatives (like Ivana, her brother is a soccer star & Matías S., his brother is a famous tennis player) or they dated them (like Lucas; who dated a widely known journalist & Macarena, who has dated high profiled men). Also, both Luis Fabián "Luifa" Galesio and Cynthia Aller were relatively known prior to enter Gran Hermano.

Marian García was a housemate on Gran Hermano 2015 and entered in this series as one of the two replacements (the other one was this season's Yasmila) chosen by the public for Macarena who quit on Day 22. On Day 57, Ainelén & Bárbara were announced as official housemates by Gran Hermano, after they survived 1 week in the House as their final tryout to become the new housemates.
