Big Brother Wiki

"My house, my rules, my game. I am Big Brother." Big Brother Australia

Big Brother (person), considered as the most important element in the series, is the unseen voice that controls the housemates' lives inside the house.

The titular character is loosely based on a fictional character with the same name from George Orwell's novel, Nineteen Eighty-Four, where the reality series was inspired from.


Big Brother is a well-known and notorious character in the reality series, and he is the owner of the Big Brother House where the housemates live under his command. Big Brother is an unseen and omnipotent entity that watches the housemates' every move, and neither the contestants nor the viewers can see him physically. However, the housemates can privately converse with him and express their thoughts and emotions through a special room called the Diary Room.

In different versions of the series throughout the world, Big Brother is addressed in many terms, and often, in their country's national language. For instance, in the Philippines, the housemates sometimes call Big Brother Kuya, a Filipino honorific/kinship term used to refer to an elder male sibling or an older male friend. In Indian versions of the series, the contestants address him as Bigg Boss, while in Big Brother Nigeria, the housemates call him by the nickname Biggie. In other versions, they refer to Big Brother in their languages' translation of the term such as Grande Fratello in Italian, Gran Hermano in Spanish and HaAh HaGadol in Israel . In Vietnam, Big Brother is called Anh Hai. In Spain, the housemates call him Super while in Spanish USA & Mexico (both Celebrity), they call Big Brother Jefa (Boss, female voiced) and Jefe (Boss, male voiced) in Colombia (Celebrity).

Man of the House[]

As the iconic figurehead of the international Big Brother franchise, Big Brother is known for his deep, paternal voice and commanding persona. He is a fundamental part of the show, with his rules dictating the everyday lives of the housemates. It is a major rule inside the house to follow Big Brother at all times, and any refusal to do so is considered a severe violation that could lead to punishment, most often ejection from the show.

Despite his authoritative presence, Big Brother's strictness towards the housemates may vary from season to season, with some iterations featuring a more lenient Big Brother and others featuring a more strict one. These changes are often caused by twists within the season, which could challenge the housemates in new ways and require a different approach from Big Brother. Overall, Big Brother's role in the show is crucial to the success of the Big Brother franchise, and his influence on the housemates and the audience cannot be overstated.

House Guardian[]

Another aspect that varies between different versions of Big Brother is his personality. In some versions, notably Big Brother Australia and Pinoy Big Brother, Big Brother is characterized as a wise authority figure with a right combination of humor, mischief, seriousness, and strictness, which is often seen throughout the series during Diary Room conversations, tasks, and during the twists he implements inside the house.

In the Philippine version for instance where it is notable for producing Teen seasons and casting teenagers, Big Brother's characterization in the show has evolved into an all-knowing and wise father figure who often shares a lot of wisdom and life advices towards his adolescent and adult houseguests. Apart from the Philippines, Big Brother is a house guardian in Argentina, Australia, Bulgaria, Chile, Colombia, Czech Republic, Greece, India, Israel, Mexico, Nigeria, Poland, Portugal, Serbia, Slovakia, South Africa, the UK and the USA (Spanish).

Lessened Prominence[]

In some versions, Big Brother is considered a less prominent character in the show or even non-existent at all. Big Brother (U.S), for example, is notable for lacking a prominent Big Brother figure, although a Big Brother voice can sometimes be heard in the show only when commanding houseguests to do specific actions such as going to the diary room, or turning on the lapel microphone if it's accidentally turned off by the houseguests. Since it's not a prominent character in the show, most of the duties done by the role are carried out by the producers themselves, often Allison Grodner, such as giving various announcements to the house. Instead, the persona became more known in the show simply as "production", rather than "Big Brother". As a result of the minimized appearance of the Big Brother character, the housemates themselves and even the host, Julie Chen have taken out some duties often performed by Big Brother in other versions, such as hosting the competitions and presiding the nominations and evictions.

Despite the Big Brother voice having less impact on the American version's narrative since the 2nd season, it has been revealed in a 2020 article that the majority of the houseguests have formed a connection with Big Brother throughout their time inside the house. Many fans who watch the show's live feeds have also been familiarized with Big Brother commanding his houseguests despite that such moments weren't usually included in the show's television broadcast.[1]

During the first two iterations of Big Brother UK, Big Brother was also not a prominent character on the show, instead, the role was carried out by various producers, lacking the mystery of a larger figure and presenting events as more adult and realistic. The producers usually talked with a very straight and serious tone, although sometimes made minor efforts at humor. When housemates violated the rules, they would either be called into the Diary Room and be told off or scolded by housemates from a loudspeaker. 

Apart from the United States and Canada, Big Brother is less prominent in other countries such as Brazil, Spain, Albania, and Kosovo. These countries have a less intense surveillance culture compared to North America. This means that surveillance intensity varies across different locations, and not every place undergoes the same level of constant monitoring and control.

Playful Personality[]

For some instances, Big Brother can be a little bit playful, playing tricks and secret missions to the housemates. These playful tricks and secret missions set up by Big Brother really add to the excitement of an already intense game, leaving housemates and viewers alike wondering what surprise is just around the corner. This is what makes Big Brother unique. Each season brings new challenges and surprises to keep fans on the edge of their seats, wondering what devious twist Big Brother will unleash next. It's a wild ride of strategy, deception and pure, raw fun that keeps viewers coming back for more, season after season.

Big Brother's playful personality is most notably in Argentina, Australia, Belgium/Netherlands, Bulgaria, France, Germany, Greece, India, Israel, Nigeria, Philippines, Portugal, South Africa and the UK. In the Portuguese version, Big Brother laughs mischievously at the housemates, leaving them clueless, while in Australia, Big Brother really takes the secret missions to the next level.
