Big Brother is a dutch reality competition television franchise created by John de Mol Jr, first broadcast in the Netherlands in 1999, and subsequently syndicated internationally. It was originated from the novel 1984, written by George Orwel, where there is a theme of continuous oppressive surveillance of housemates by live TV cameras and audio microphones.

In Nigeria, it is widely known as Big Brother Naija and different versions in other countries of the world.

Multichoice Nigeria serves as the organiser of the show and is reportedly also an owner of the show. As of September 2019, there have been more than 488 seasons of Big Brother in over 54 franchise regions and countries.

BBNaija is one of Nigeria’s top and most-watched reality programs. This show gathers contestants of different ages but not younger than 21 years from different backgrounds to live in a house together for about 95 days more or less to contest for a grand price worth millions of naira. The housemates are isolated in a house and made to live together under the surveillance of Big Brother, who is always watching 24/7.
