Gran Hermano (also known by the acronym GH) is the upcoming Uruguayan version of the international reality television franchise Big Brother created by producer John de Mol Jr. in 1999.
The Big Brother reality series was created by John de Mol Jr. and premiered in the Netherlands. In Uruguay, the Argentine edition broadcast on Telefe consistently achieved strong ratings. As a result of a 2023 agreement between Telefe and Channel 10, beginning with the eleventh season Uruguayan contestants were incorporated into the competition. These included Bautista Mascia and Santiago Algorta, both of whom went on to win their respective seasons. The agreement further permitted viewers in Uruguay to vote via text message.
In May 2025, Argentine producer Alejandro Ripoll confirmed that the house used for the Argentine edition would be repurposed for a forthcoming Uruguayan adaptation, expected to premiere in the latter half of 2026. This approach follows the precedent set by the Chilean version, aired between 2023 and 2024, which was also produced in the same facilities owned by Kuarzo Entertainment.
On 14 October 2025, after several days of airing promotional spots featuring visual elements associated with the programâÂÂwithout explicitly confirming the projectâÂÂthe network officially announced the production of a Uruguayan adaptation of the format. On 18 February 2026, it was further announced that Eduardo Gianarelli would serve as the programâÂÂs host.
Gran Hermano is a reality television game show in which a group of contestants, known as âÂÂhousemates,â live together in isolation from the outside world inside a custom-built house. The participants are continuously monitored by video surveillance and overseen by âÂÂGran Hermano,â an unseen voice that observes their conduct, assigns weekly tasks and penalties, and relays their requests.
During their stay in the house, each housemate is required to nominate two fellow contestants for possible eviction. The two or more contestants receiving the highest number of nominations are then placed on the public vote, with viewers ultimately deciding who will be evicted.
