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.


Within the infamous reality series, Big Brother is known as the owner of the Big Brother House, wherein a group of housemates live under his command and must avoid evictions. However, Big Brother is considered to be an unseen, omnipresent, 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 and express their thoughts and emotions with Big Brother through a special room in the Big Brother House called the Diary Room, or a Confession Room in some versions.

Interestingly, in many versions of the series, Big Brother is addressed in many terms, oftentimes in their country's national language. In the Philippines, Big Brother although officially called as such, is also called as "Kuya", a Filipino honorific/kinship term normally used to refer to an elder male sibling or an older male friend. In Indian versions of the series, the contestants call him instead as Bigg Boss. Meanwhile, in the Big Brother Nigeria, the contestants also call him with the nickname Biggy. In other versions, they call Big Brother in their languages' translation of the term such as Grande Fratello in Italian and Gran Hermano in Spanish.

In most of the international versions of the series, Big Brother is known to have a deep, father-like voice and often has a commanding persona. It is a major rule in the house to follow Big Brother at all times, and refusing to do so is considered as a major violation and would have corresponding punishment, the worst being ejection. In most versions of the series, his strictness towards the housemates may vary; in some seasons, Big Brother can be strict, while in other seasons, he can be tolerant of the actions inside the house. Oftentimes, these changes are caused by certain twists within a season.

Wise Guardian

Another thing 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.

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 certain 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, oftentimes 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 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 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]

In Big Brother UK, Big Brother is also not a prominent character on the show, instead, the role is carried out by various producers, lacking the mystery of a larger figure and presenting events as more adult and realistic. The producers usually talk with a very straight and serious tone, although sometimes making minor efforts at humor. When housemates are violating the rules, they will either be called into the Diary Room and be told off or will scold housemates from a loudspeaker.
