A reality show is a television program that features real people, rather than actors, in unscripted situations. These shows often focus on various themes, such as competition, relationships, or lifestyle changes. Participants are typically filmed in their everyday lives or during specific challenges, allowing viewers to see their genuine reactions and interactions. Reality shows can vary widely in format, from talent competitions like American Idol to lifestyle series like Keeping Up with the Kardashians. They often aim to entertain and engage audiences by showcasing drama, humor, and personal stories, making them popular across different demographics.
