Editing Voice-over (section)

===Educational or descriptive device===
The voice-over has many applications in non-fiction as well. Television news is often presented as a series of video clips of newsworthy events, with voice-over by the reporters describing the significance of the scenes being presented; these are interspersed with straight video of the [[news anchor]]s describing stories for which video is not shown.

Television networks such as [[History (U.S. TV channel)|The History Channel]] and the [[Discovery Channel]] make extensive use of voice-overs. On [[NBC]], the television show ''[[Starting Over (TV series)|Starting Over]]'' used Sylvia Villagran as the voice-over narrator to tell a story.

Live sports broadcasts are usually shown as extensive voice-overs by [[sports commentator]]s over video of the sporting event.

[[Game show]]s formerly made extensive use of voice-overs to introduce contestants and describe available or awarded prizes, but this technique has diminished as shows have moved toward predominantly cash prizes. The most prolific have included [[Don Pardo]], [[Johnny Olson]], [[John Harlan (announcer)|John Harlan]], [[Jay Stewart]], [[Gene Wood]] and [[Johnny Gilbert]].

Voice-over commentary by a leading critic, historian, or by the production personnel themselves is often a prominent feature of the release of feature films or documentaries on [[DVD]]s.
