* ''Literature/TheRedVixenAdventures'' uses some form of instant communication, which isn't specified beyond being very expensive.

* Usually, the ''{{Metroid}}'' games avoid this by having no form of communication through space, but in ''Metroid Prime: Hunters'', it's stated that a signal was sent to various bounty hunters via a telepathic frequency.

* James Hogan uses a similar system (and also worked in the computer industry -- for DEC during the PDP minicomputer days) in his ''Gentle Giants'' series of books where both communication ''and'' FTL travel are accomplished through rotating black holes. ''Toroidal'' black holes. A similar concept is used in his book ''The Genesis Machine,'' in which a Cold War era book about a machine that is initially used to pull information from remote places in real time ''without'' there being a device on the other end to transmit the data is turned into a superweapon to stop the Cold War in its tracks -- by causing a nuclear exchange and destroying the missiles before they hit the ground.

* White Radio in the ''MatadorSeries''. Oddly for most of the series, it only transmits video in black-and-white; color is added on the receiving end, and looks kinda fake.

*''VideoGame/StarControl'': the [[StarfishAliens silicon-based]] Chenjesu are described as natural hyperspace communicators. The franchise features also the typical (artificial) FTL 'casters,in seemingly real time.

* Our universe in ''FineStructure'' used to allow FTL communication (and FTL travel), and nobody knows when [[spoiler: the Imprisoning God excised FTLC from reality.]] That is the reason there are only nine FTLC engineers on Earth.

The term "ansible" for this kind of near-instantaneous subspace communication system was coined by Creator/UrsulaKLeGuin in her 1966 novel, ''Rocannon's World''. "Ansible" is a derivation of "answerable,"; i.e., "messages will be answerable in realtime." Many other science-fiction writers picked up the name after Le Guin.

* The TropeNamer appears in most of Creator/UrsulaKLeGuin's ''Ekumen'' novels. Le Guin devised "ansible" as a contraction of "answerable."
** In ''The Dispossessed'' she tells, among other things, the story of its invention.
** In ''The Left Hand of Darkness'' it's clarified that the ansibile needs a significant gravity source to work, so one "end" of the connection is a "stabile" and must be fixed on a planet while the "ansibile" is portable.
** In the world of the Ekumen, there is no faster-than-light space travel, but there are FTL weapons. No living thing can survive FTL but unmanned ships have no problem. In ''Rocannon's World'', there are FTL ships packed with bombs whose pilots are effectively suicide bombers, ready to sacrifice themselves in a case of dire emergency.

* Inexplicably possible in the Soviet two-part sci-fi film ''Film/MoscowCassiopeia'', where the teen cosmonauts are able to attend classes via teleconference while in interstellar space. Later, when they end up traveling at near-light speeds and end up at their destination early (from their viewpoint), they talk to mission control back on Earth in real-time. There is also the moment where [[MenInBlack IOO]] uses a rotary pay phone and a metal cigar case to show real-time footage of the starship to TheCaptain's parents, but his abilities appear to be far beyond what's possible even in the film's science.

* ''Series/DefyingGravity'' is near future and mostly hard scifi, but the ship has instant communication with earth on multiple channels in at least the megabit range (hd video transmissions, internet use, etc), handwaved as being brand new tech that made the mission possible in the first place.

** Similarly, grisly rumours, perhaps inspired by the "powder of sympathy" theory, emerged during the Cold War that both the USSR and USA were testing out the fringe idea that psychic communication not only worked, but worked instantaneously, by separating a mother animal from her newborn young, which went to sea on a submarine whilst the mother stayed at home in a research lab. At prearranged times, one of the baby animals would be killed whilst the home lab monitored the mother for a sign of sudden unmistakeable distress. Baby rabbits and kittens have been suggested as the most likely test subjects.

* ''[[Anime/VoicesOfADistantStar Voices of a Distant Star]]'' subverts this by structuring the entire plot (and title of the work) around the delay in communication.
