Definition of the word peep show

The term "peep show" originally referred to a type of theatrical performance that gained popularity in the 19th century. It involved a small, enclosed space with a transparent door or window called a "peephole," where performers would put on intimate or humorous acts, such as actresses changing costumes, dancers performing intricate routines, or animal trainers presenting their acts. The audience would pay a small fee to view these performances through the peephole, granting them a private and voyeuristic experience. The term "peep show" eventually came to refer to the privately-viewed photographic displays of nude models in booths that became popular in the mid-20th century, and the term has since expanded to include other types of adult entertainment, such as striptease clubs and webcam performances.
