What is Sketch: Definition and 185 Discussions

Sketch comedy comprises a series of short scenes or vignettes, called "sketches", commonly between one and ten minutes long. Such sketches are performed by a group of comic actors or comedians, either on stage or through an audio or visual medium such as radio and television. Often sketches are first improvised by the actors and sketched down based on the outcome of these improv sessions; however, such improvisation is not necessarily involved in sketch comedy.
An individual comedy sketch is a brief scene or vignette of the type formerly used in vaudeville, and now used widely in comedy and variety shows, talk shows, and some children's television series (such as The Electric Company).
Sketch comedians routinely differentiate their product from a "skit", maintaining that a skit is a (single) dramatized joke (or "bit") while a sketch is a comedic exploration of a concept, character, or situation.
