The concept of reality show is a very recent concept that is used in the field of communication media and entertainment to refer to a type of television program that is characterized by showing in a real and truthful way the different experiences that a person or a group of people have them throughout their day. The idea of the reality show is precisely to avoid fiction and show a reality that is not intervened or that is in the least possible way. The concept of reality show is undoubtedly one of the most controversial and discussed in recent times because it involves a certain invasion on the lives of those portrayed and a certain loss of privacy regarding their tasks or intimate topics.
Throughout the second half of the 20th century, numerous programs have been developed that aimed to show in a documentary and real way different aspects or themes of people's lives, for example, the work of policemen in the streets, of documentary writers, of games , etc. However, it was not until the 1990s that this type of television programming exploded in popularity from different programs that aimed to show the simple and common life of people who did not present any specialty or particularity. Some of these programs only portrayed the ordinary lives of people who thus lost their privacy and intimacy without showing any specific talent or ability.
The program that undoubtedly made the concept of reality show an event was known as Big Brother or Big brother in English. This program aims to present a variable number of contestants in competition who all they have to do is live together for a particular period of time in a house, without previously knowing each other and without maintaining any type of contact with the outside. What happens inside the house is reproduced by endless cameras, so there is no way to do something that is not seen by the viewers. A popular success in many countries around the world, this television format has been widely criticized for generating an artificial reality and sometimes even dangerous for the mental health of the participants.
