What are variety show origins?

Variety shows originated in the early 19th century as a form of entertainment in theaters, combining various acts such as music, dance, comedy, and acrobatics. They gained popularity in the United States during the vaudeville era, where performers showcased diverse talents in a single performance. This format transitioned to radio and television in the mid-20th century, leading to iconic shows that featured a mix of celebrity guests, skits, and musical numbers, ultimately shaping the landscape of modern entertainment.
