Reality television is a genre of television programming that documents purportedly unscripted real-life situations, often starring unfamiliar people rather than professional actors. Reality television emerged as a distinct genre in the early 1990s with shows such as The Real World, then achieved prominence in the early 2000s with the success of the series Survivor, Idol, and Big Brother, all of which became global franchises. Reality television shows tend to be interspersed with "confessionals", short interview segments in which cast members reflect on or provide context for the events being depicted on-screen; this is most commonly seen in American reality television. Competition-based reality shows typically feature the gradual elimination of participants, either by a panel of judges, by the viewership of the show, or by the contestants themselves.
