A sitcom, clipping for situational comedy, is a genre of comedy centered on a fixed set of characters who (mostly) carry over from episode to episode. Sitcoms can be contrasted with sketch comedy, where a troupe may use new characters in each sketch, and stand-up comedy, where a comedian tells jokes and stories to an audience. Sitcoms originated in radio, but today are found mostly on television as one of its dominant narrative forms.
