Not the Nine O'Clock News is a British television sketch comedy show which was broadcast on BBC2 from 16 October 1979 to 8 March 1982. Originally shown as a comedy alternative to the Nine O'Clock News on BBC1, it features satirical sketches on then-current news stories and popular culture, as well as parody songs, comedy sketches, re-edited videos, and spoof television formats. The programme features Rowan Atkinson, Pamela Stephenson, Mel Smith, and Griff Rhys Jones, as well as Chris Langham in the first series.

Sketch comedy comprises a series of short, amusing scenes or vignettes, called "sketches", commonly between one and ten minutes long, performed by a group of comic actors or comedians. The form developed and became popular in vaudeville, and is used widely in variety shows, comedy talk shows, and some sitcoms and children's television series. The sketches may be improvised live by the performers, developed through improvisation before public performance, or scripted and rehearsed in advance like a play. Sketch comedians routinely differentiate their work from a "skit", maintaining that a skit is a (single) dramatized joke while a sketch is a comedic exploration of a concept, character, or situation. Sketch comedy is a genre within American television that includes a multitude of schemes and identities.
