Reality Television
1. Reality television is a genre of television programming that documents unscripted situations and actual occurrences, and often features a previously-unknown cast. The genre often highlights personal drama and conflict to a much greater extent than other unscripted television such as documentary shows. The genre has various standard tropes, such as reality TV confessionals used by cast members to express their thoughts, which often double as the shows’ narration. In competition-based reality shows, a notable subset, there are other common elements such as one participant being eliminated per episode, a panel of judges, and the concept of immunity from elimination.
