Big Brother is a reality TV show like no other. Below is a description of the show, based on findings through Wikipedia.

Initially shown in the Netherlands in September 1999, and subsequently cloned across the world, the "housemates" are confined inside a specially designed house, and not permitted any contact with the outside world: no TV, radio, telephone, internet or other media are available to the housemates, not even writing materials. Private chats with a psychologist are a special exception. At weekly intervals, the public is invited to vote to evict one of the contestants. The last remaining is the winner. It is similar to the balloon problem where a balloon is sinking and someone has to be forced to bail out in order to keep the balloon afloat.

Besides the same living together, which is the principal axis and major attraction of the contest, this one turns concerning 4 basic props: the stripped-bare back to basics environment in which they live, the evictions system, the weekly tasks set by Big Brother, and the "diary room", in which the housemates individually convey their thoughts, feelings, frustrations and their eviction nominees.

Initially, the hostel in which they had to reside for the duration of the competition was very basic. Although essential amenities such as running water, furniture and a limited ration of food were provided, luxury items were forbidden. This added an element of survival into the show, thus increasing the potential for tensions within the house. Now almost every country have a nice house for the contest, with Jacuzzi, sauna, VIP suite, etc. in contraposition to other zones, or characteristics, of the house, more common, even precarious.

To fill in time, the residents have various chores to maintain the house, and are set apparently random tasks by the producers of the show, who communicate with the housemates through one (unseen) individual issuing commands, termed "Big Brother". The tasks are designed to test their team-working abilities and community spirit. The housemates have a weekly allowance with which they can buy food and other essentials. To obtain a greater allowance, they may gamble some of their initial amount on the success of the completion of tasks. Of course, their allowance is lessened if they fail to complete the weekly task.

Each week, the housemates each privately nominate a number of people who they wish to see removed from the house more than the other residents. The ones with the most nominations are then named on the television show, and viewers can call a special premium rate telephone number, send a premium rate text message or in some areas by digital interactive red button services to vote for whom they want to evict.

After the votes are tallied, the "evictee" leaves the house and is interviewed on-camera by the host of the show, usually in front of a live studio audience. The last remaining housemate is declared the winner and receives a substantial sum in prize money, the amount of which has varied widely around the world.

The series is notable for involving the Internet. Although the main show, typically broadcast daily with a weekly roundup, is by necessity heavily edited, viewers can also watch a continuous, 24-hour feed from multiple cameras on the web. These websites were highly successful, even after some national series started charging for access to the video stream. In some countries, the Internet broadcasting was supplemented by updates via email, WAP and SMS. The house is even shown live on satellite television (with a 10-15 minute delay to permit muting of unacceptable content in the UK). Indeed, John de Mol has said: "We aren't really a television producer at all anymore. We are a content provider for multiple platforms."

Despite derision from many intellectuals and other critics, the show has been a commercial success around the world. Criticisms typically are based on the ironic aspects of George Orwell's dystopic vision of Nineteen Eighty-Four being consciously aped by producers for public entertainment. More generally, the voyeuristic nature of the show, where contestants volunteer to surrender their privacy in return for minor celebrity status and a comparatively small cash prize, has attracted much scorn.

While any pretences to be a cultural experiment are dubious, reports of the different results of the show around the world have been mildly interesting from a pop-anthropology standpoint; i.e., in Spain, the competitors designed an agreement to achieve they all were nominated automatically and annul then their power of decision inside the process of elimination in the contest. This only happened once, as afterwards, Big Brother modified its rules to prohibit this type of agreement. On the other hand, other versions have involved plotting in the vein of the most cruel soap opera. Some versions have been filled with sex-crazed housemates, whereas others decided to base the conflict within their programs around difficult or romantic personalities, as in Brazil, Mexico or Spain. With the passing of time, it has been demonstrated that the most successful versions have emulated a soap opera, whereas the versions where the principal attraction was sex have been eliminated, as in Hungary or Poland. The amount of sex shown on the televised versions varies from country to country depending on censorship rules, with some countries editing out all sex and nudity, and others allowing the show to verge on the pornographic.

The majority of winners have been men, although a number of countries have now had a female winner. Although a number of countries have (knowingly) included transsexual contestants, only one has won (Nadia Almada, UK)

One interesting development is that German scientists have discovered that former Big Brother contestants may be at risk from Post-Traumatic Stress Disorder, a condition sometimes suffered by those who leave the armed forces. Indeed, in the second Polish edition, one of the housemates was taken to a psychiatric hospital.

The format has also spawned novels, in particular Ben Elton's book Dead Famous about the televised death of a housemate.
