In return for their appearance on I'm a Celebrity...Get Me Out of Here!, the celebrities are asked to nominate a charity to which the producers, LWT (weekend shows) and Granada Television (weekday shows), make donations. The celebrities themselves are also paid a fee to compensate them for possible loss of earnings while they are in the jungle. The producers of the show keep the precise details of the celebrities' contracts private, prompting much speculation from the media. The money is raised by allowing viewers to vote by phone, text message or the "red button" (a colloquialism popular in the UK for TV interactive services) for the celebrity they would like to complete a "Bush Tucker Trial" — a physical task usually involving snakes, spiders or other creepy-crawlies found in the jungle — and, later in each series, to vote for the celebrity they would like to see win the show. The last remaining celebrity after all others have been evicted is declared the winner of the show, and is branded "King/Queen of the Jungle".
