Holography has been widely referred to in movies, novels, and TV, usually in [[science fiction]], starting in the late 1970s.<ref name=":0">{{Cite book|title=Holographic Visions: a History of New Science.|url=https://archive.org/details/holographicvisio00john_090|url-access=limited|last=Johnston|first=Sean|date=2006|publisher=Oxford University Press, UK|isbn=978-0191513886|location=Oxford|pages=[https://archive.org/details/holographicvisio00john_090/page/n427 405]–408|chapter=The Hologram and Popular Culture|oclc=437109030}}</ref> Science fiction writers absorbed the [[urban legend]]s surrounding holography that had been spread by overly-enthusiastic scientists and entrepreneurs trying to market the idea.<ref name=":0" /> This had the effect of giving the public overly high expectations of the capability of holography, due to the unrealistic depictions of it in most fiction, where they are fully [[Volumetric display|three-dimensional computer projections]] that are sometimes tactile through the use of [[Force field (fiction)|force fields]].<ref name=":0" /> Examples of this type of depiction include the hologram of [[Princess Leia]] in [[Star Wars (film)|''Star Wars'']], [[Arnold Rimmer]] from ''[[Red Dwarf]]'', who was later converted to "hard light" to make him solid, and the [[Holodeck]] and [[The Doctor (Star Trek: Voyager)|Emergency Medical Hologram]] from ''[[Star Trek]]''.<ref name=":0" />

Holography has served as an inspiration for many video games with science fiction elements. In many titles, fictional holographic technology has been used to reflect real life misrepresentations of potential military use of holograms, such as the "mirage tanks" in ''[[Command & Conquer: Red Alert 2]]'' that can disguise themselves as trees.<ref name=":12">{{Cite book|title=Holograms: A Cultural History|last=Johnston|first=Sean F.|publisher=Oxford University Press|year=2015|isbn=978-0191021381|chapter=11 - Channeling Dreams}}</ref> [[Player character]]s are able to use holographic decoys in games such as ''[[Halo: Reach]]'' and ''[[Crysis 2]]'' to confuse and distract the enemy.<ref name=":12" /> ''[[StarCraft|Starcraft]]'' ghost agent Nova has access to "holo decoy" as one of her three primary abilities in ''[[Heroes of the Storm]].<ref>{{Cite web|url=http://us.battle.net/heroes/en/heroes/nova/|title=Nova - Heroes of the Storm|website=us.battle.net|language=en-us|access-date=2019-10-20}}</ref>''

Fictional depictions of holograms have, however, inspired technological advances in other fields, such as [[augmented reality]], that promise to fulfill the fictional depictions of holograms by other means.<ref>{{Cite book|title=The Hologram: Principles and Techniques|last=Richardson|first=Martin|others=Wiltshire, John D.|isbn=978-1119088905|location=Hoboken, NJ|oclc=1000385946|date = 2017-11-13}}</ref>
