Reality TV, short for reality television, is a genre of television programming that purports to document unscripted real-life situations and often features ordinary people instead of professional actors. Reality TV shows may involve competitive formats, where participants face challenges or tasks, or they may follow the day-to-day lives of individuals or groups, showcasing their interactions, relationships, and personal dramas. This genre emerged in the late 20th century and has since gained immense popularity, leading to a variety of formats, including dating shows, talent competitions, and lifestyle or makeover shows. Reality TV often emphasizes entertainment value and audience engagement, blurring the lines between reality and scripted content.
