Big Brother is a reality show based on the Big Brother series by Endemol. The show originates from the Netherlands, where in 1999 the first season was aired.
At present, the format is spread in a number of countries around the world. A group of people (called the Housemates) live together in an isolated house. 24 hours a day their life is recorded by hidden cameras in all the rooms in the House. They do not have TV, Internet, newspapers, even watches on their wrists. The Housemates are completely isolated from the outside world. Every week, each one of them must enter the Diary room and nominate two of the other people for public eviction. The two or more housemates with most negative votes become nominated. For almost a week the TV viewers have to decide which of them to be evicted, voting via SMS or phone calls. Every week the Housemates have a week task. Depending on whether they perform their task successfully or unsuccessfully, their week budget is increased or decreased. During the final week, the viewers vote which one of the remaining people in the House to be the winner, who receives a large cash prize.
The show's name comes from George Orwell's 1948 novel Nineteen Eighty-Four, a dystopia in which Big Brother is the all-seeing, omnipotent leader of Oceania.
In Bulgaria, the first season of Big Brother was aired in 2004 on Nova Television, and quickly became one of the most successful TV formats in the country. Niki Kanchev was the main presenter in all editions, except for Big Brother 4, where he was replaced by Milen Tsvetkov. Evelina Pavlova was a co-host in the period 2004–2006. Five main seasons, ten celebrity seasons, four All Stars seasons, two Most Wanted seasons and a Family season have been produced so far. The fifth main season premiered on 17 August 2015 and was the first non-celebrity season to be produced in seven years.
