Big Brother UK
In short
A British reality television programme where a group of contestants live together in a specially constructed house, isolated from the outside world. The show relies on constant camera and microphone surveillance to monitor the housemates' every move.
In plain words
A group of strangers live in a house and are filmed all day and night. They cannot talk to anyone outside or use phones. Viewers watch them interact and vote to decide who stays or leaves.
A simple example
A group of ten people enter a house for several weeks. They must complete tasks to win food, while the public votes to evict their favourite or least favourite person each week.
Why it matters
It pioneered the modern reality TV genre in the UK. The show explores human behaviour, social dynamics, and the ethics of constant surveillance.
Easy to mix up
Do not confuse it with the American version, which has different rules and a different tone.
