Stand-up comedy shows usually feature a comedian performing on stage, telling jokes, and delivering humorous stories to an audience. Sketch comedy shows often involve a group of performers acting out humorous skits and parodies. Improv comedy shows are typically unscripted performances where performers create comedic scenes and characters on the spot, often based on audience suggestions. Sitcoms, on the other hand, are scripted television shows that feature a recurring cast of characters in comedic situations.
