Secret Story is a French reality competition television show. Despite not being a direct adaptation of the Big Brother franchise's format, created by producer John de Mol in 1997, the show has a similar concept while including his own game mechanics, and is also produced and owned by Endemol Shine Group/Banijay.

Big Brother is a reality competition television franchise created by John de Mol Jr., first broadcast in the Netherlands in 1999 and subsequently syndicated internationally. The show features contestants called "housemates" or "HouseGuests" who live together in a specially constructed house that is isolated from the outside world. The name is inspired by Big Brother from George Orwell's novel Nineteen Eighty-Four, and the housemates are continuously monitored during their stay in the house by live television cameras as well as personal audio microphones. Throughout the course of the competition, they are voted out until only one remains and wins the cash prize.
