Where did improv come from?

Improv, or improvisational theater, originated in the early 20th century, drawing inspiration from various theatrical forms, including commedia DELL'arte and vaudeville. It gained prominence in the 1950s with the establishment of groups like The Compass Players and The Second City in Chicago, which emphasized unscripted performances and audience interaction. Improv has since evolved into a popular art form, influencing comedy, theater, and even education. Its roots can be traced back to the idea of spontaneous creativity and collaboration among performers.
