** The synopsis for Series 11 finale [[Recap/DoctorWhoS37E10TheBattleOfRanskoorAvKolos "The Battle of Ranskoor Av Kolos"]] ends by stating that the Doctor and her friends will be led "towards a deadly reckoning", implying dire things. However, the synopsis for the New Year's special, released the ''very next day'', makes it clear that the Doctor and all three companions, Ryan, Graham and Yaz, survive. At the time of writing, it's too early to tell whether or not this is a straight example or a subversion, but it certainly smacks of spoilers.

At the time of writing, it's too early to tell whether or not this is a straight example or a subversion, but it certainly smacks of spoilers.

** However, a few episodes that have pulled the OurHeroIsDead cliffhanger notably avert this by having the following trailers show no signs of Jack in them to keep his survival somewhat more suspenseful ([[ContractualImmortality for all the good they do, anyway). However, at the same time they ''do'' spoil some other key twists happening to some other characters within the episode.

** ''All'' the pre-publicity for Creator/JodieWhittaker's first season spoils the end of the first episode, [[Recap/DoctorWhoS37E1TheWomanWhoFellToEarth "The Woman Who Fell to Earth"]]. The publicity [[spoiler:made much of the Doctor's three companions, Graham, Ryan and Yazmin]]. So when the episode [[spoiler:features a ''fourth'' member of the group, Grace, Graham's wife and Ryan's gran, who is the most enthusiastic about entering the Doctor's world]], it's fairly obvious [[spoiler:she's not going to make it to the end credits]].

** [[DiscussedTrope Discussed in the DVD commentary]] on Next Time trailer at the end of [[Recap/DoctorWhoS29E11Utopia "Utopia"]], where the producers point out that they deliberately avoided using any shots of [[spoiler:the Doctor, Martha Or Jack, implying that they were still trapped like they were in the cliffhanger]]. This might also count as NeverTrustATrailer, as it implied that the episode would [[spoiler: focus on the Master rather than the Doctor and his companions]]. In the actual episode [[spoiler:the Doctor's successful arrival in modern London is literally the first shot]].

** ''All'' the pre-publicity for Creator/JodieWhittaker's first season spoils the end of the first epsisode [[Recap/DoctorWhoS37E1TheWomanWhoFellToEarth "The Woman Who Fell to Earth"]].

* ''All'' the pre-publicity for Creator/JodieWhittickar's first season spoils the end of the first epsisode [[Recap/DoctorWhoS37E1TheWomanWhoFellToEarth "The Woman Who Fell to Earth"]].

** Subverted with the trailers for the 2017 ChristmasEpisode [[Recap/DoctorWho2017CSTwiceUponATime "Twice Upon a Time"]]. They gave away that [[spoiler:Bill Potts and the Doctor are reunited]], which doubled as a LateArrivalSpoiler for a major twist in the previous episode, ([[spoiler:Bill's restoration to human(oid) form]]). The subversion? [[spoiler: She's actually a Glass Person avatar of Bill, who is elsewhere living her own life.
For all intents and purposes they're the same person, but it's hard for the Doctor to accept this idea]].

** The first trailer for the 2017 ChristmasEpisode [[Recap/DoctorWho2017CSTwiceUponATime "Twice Upon a Time"]] reveals [[spoiler:Bill Potts and the Doctor are reunited]], which ''could'' have been a huge surprise as [[spoiler:she'd just left, seemingly for good, at the end of "The Doctor Falls"]]. To make matters worse, this doubled as a LateArrivalSpoiler for a major twist in "The Doctor Falls" ([[spoiler:Bill restored to human(oid) form]]).

* ''Series/BattlestarGalactica2003'': This trope happens pretty often in the show's trailers. The promo for "Resurrection Ship, Part 2", apparently attempted to be discreet in its final frame, which showed a hand holding a gun, aimed at Admiral Cain's head. However, the shot of the hand was detailed enough that many astute viewers were able to determine that it was [[spoiler: "Gina", the Number Six Cylon imprisoned on the Pegasus]], well before the resolution aired.

** In the trailer for ''Revelations'', [[spoiler:every scene but one has already occurred by the episode's apparent ending, and that one scene can literally be missed if the viewer blinked. Even when you see it, it's ambiguous.]]
** The trailer for ''The Ties That Bind'' pretty much gives away the fact [[spoiler:that Cally doesn't survive the episode]], though how and why are still a mystery.

** ''Creator/TheHub'' had an interesting case. The trailers showed the newly-ressurrected [[spoiler: D'Anna]] telling [[spoiler: Roslin]] that she is a Cylon. Many viewers wondered if it was real or creative editing. As it was revealed, [[spoiler: D'Anna]] ''did'' say that to [[spoiler: Roslin]]. However, she said to to mess with [[spoiler: Roslin]]'s head. In the commentaries of the episode, [[WordOfGod Ronald D. Moore]] expressed great anger that they ruined the joke by putting it in the trailer.

* ''HollywoodShowdown'': When TV Guide Channel re-aired episodes (which was 30 minutes), they would pad out the show with commercials to make it an hour long. Towards the end of the hour, they would run the first five minutes or so of the next episode.

* ''Series/H2OJustAddWater'' got a major Season 2 plot point spoiled by Nickelodeon before the series aired in the UK. Previews showed [[spoiler: Charlotte underwater with a mermaid tail]] - which does not happen until well into the second half of the season. Also not as bad, as the first episode hinted at it, but the previews implied that [[spoiler: Charlotte would also be an antagonist]], which again doesn't happen until the season is nearly over.

* ''Series/{{Merlin 2008}}'' series 4 had a trailer for the first episode which showed Arthur carrying a lifeless Merlin. This is the cliffhanger at the end of the episode.

* ''The Mysteries Of Laura'': The trailers for the pilot (to repeat, '''the pilot''') give away that the killer in the case Laura is investigating is [[spoiler: her own boss]]. Not that that was the only problem critics and viewers had with the show...

* Certain seasons of ''SuperSentai'', such as ''Boukenger'' and ''Gekiranger'', have a nasty habit of showing story spoilers in the "next episode preview" at the end of each episode.

*** The best part of it is that the [[spoiler:Dalek attack]] scene isn't even in "Army of Ghosts" - it's from the episode after that, [[Recap/DoctorWhoS28E13Doomsday "Doomsday"]].
** The worst example in the history of the new ''Who'' is the episode [[Recap/DoctorWhoS29E4DaleksInManhattan "Daleks in Manhattan"]]. The twist ending of this is the revelation of the [[spoiler: Dalek-human hybrid]]- whose picture was on the front of the ''Radio Times''.
** The American recut trailers on Sci-Fi are even worse about this. The trailer for [[Recap/DoctorWhoS29E11Utopia "Utopia"]] gives away the last minute twist of [[spoiler: the Master's return]]. Perhaps they thought Americans wouldn't be up enough on ''Doctor Who'' history to understand it when it came, so they spelled it out for us.

*** Though as "The Stolen Earth" used [[spoiler: Daleks]] on a public location shoot for the first time since 1988, keeping their return under wraps would have been all but impossible.
** Oh, and [[Recap/DoctorWhoS30E17E18TheEndOfTime "The End of Time"]]'s DVD menu is basically a montage of the first episode's cliffhanger, giving all the plot twists away. [[spoiler: It's almost entirely made up of clips of the Master zapping around or taking control of the Immortality Gate or turning everyone into himself]]. Nice one, BBC.

** However, it was played with quite well in [[Recap/DoctorWhoS31E3VictoryOfTheDaleks "Victory of the Daleks"]] getting a ''Radio Times'' cover. It got three, each showing [[spoiler: a different Paradigm Dalek,]] but since these [[spoiler:Daleks]] had three with the colours of the major British political parties they played it off as for the election, one for each. Still spoiling, but covertly.
** The cliffhanger at the end of the opening [[Recap/DoctorWhoS32E1TheImpossibleAstronaut two]]-[[Recap/DoctorWhoS32E2DayOfTheMoon parter]] of Series 6 centers around [[spoiler: Amy shooting a little girl in a space suit.]] The trailer for Part Two not only [[spoiler: shows the girl alive and well, but also where the bullet harmlessly penetrated the space suit.]]
** One of the trailers for [[Recap/DoctorWhoS33E5TheAngelsTakeManhattan "The Angels Take Manhattan"]] shows Amy and Rory [[spoiler: falling. So the minute they get to the roof, you know what's coming...]].

** On a similar note, the US previews [[note]]This US-based troper is unsure whether the UK preview was the same[[/note]] for season 4 opened with [[spoiler: "The king is dead"]], successfully spoiling the third episode before even making headway on the season premier. Not to be deterred, it went on to display Merlin and the [[spoiler: Dorocha that (successfully) attacked him]] and the aforementioned carrying scene. And also [[spoiler: Uther's body]] [[DiggingYourselfDeeper for good measure]]. [[DeaderThanDead Just to let us know they were serious]].

* ''Series/StargateSG1'' {{lampshade|Hanging}}s this along with pretty much everything else on the episode ''200''. According to Wiki/{{Wikipedia}} the twist they're talking about ([[spoiler:Jack O'Neill's sudden appearance]]) actually made it to the commercials for the episode.
-->'''Vala''': Wow. Nobody's gonna see ''that'' coming.
-->'''Daniel''': No. There'll be spoilers.
-->'''Carter''': Are you kidding? It's gonna be in the ''commercial''.
** Also occurred in the episode "Fragile Balance". A boy of approximately 15 years attempts to gain access into the SGC. After a little info checking, the boy convinces everyone that he ''is'' Jack O'Neill. A genetic test reveals [[spoiler:that he's a clone which, for some reason, didn't age properly.]] Rather than let us find out about this little twist during the episode, the trailer showed ''adult Jack O'Neill'' stating it in no uncertain terms.

* InUniverse, [[https://www.youtube.com/watch?v=IaO-U-zJU18 this]] ''Series/MrShow'' sketch involving a guy being duped into selling drugs to an undercover cop ends with a "Next Week" teaser as the accused goes on trial:
-->'''Announcer:''' Will Kevin Ferguson be found guilty? Tune in next week! And now, here's a scene from next week's show.
-->'''Jury Foreman:''' Your Honor, we the jury find the defendant, Kevin Ferguson, not guilty.
-->'''Announcer:''' Next week, on ''America's Dumbest Juries''.

** Series 10 was '''even worse''' regarding its two-part SeasonFinale [[Recap/DoctorWhoS36E11WorldEnoughAndTime "World Enough and Time"]]/[[Recap/DoctorWhoS36E12TheDoctorFalls "The Doctor Falls"]]. First, one of the very first plot points the BBC revealed was that the original Mondasian Cybermen would appear, when the former episode is mostly spent building up to TheReveal of their presence. Then the second trailer for the season aired at the end of the season premiere [[Recap/DoctorWhoS36E1ThePilot "The Pilot"]] had a shot of [[spoiler:John Simm as the Master]], the '''second''' big twist of "World Enough and Time", which to judge by Creator/StevenMoffat's comments — including asking an audience at a screening prior to the episode's initial airing on April 15, 2017, to close their eyes before they could see it — he would rather hadn't been in the trailer at all, considering how {{unexpected|Character}} this appearance was. It wouldn't have mattered if they did, though —-- once [[Recap/DoctorWhoS36E10TheEatersOfLight "The Eaters of Light"]] aired, that twist was spoiled '''everywhere''' — the Next Time preview of [[Recap/DoctorWhoS36E11WorldEnoughAndTime "World Enough and Time"]], the poster for the episode... all for something only revealed in the last few minutes of the episode. The same Next Time trailer heavily implied that [[spoiler:Bill Potts, the primary companion in this season]] would be the mysterious character the Doctor had "pledged to protect" yet would witness the death of that Moffat teased in his pre-air synopsis, when up to that point it was just as likely to be [[spoiler:Missy, of all people]] given how the StoryArc was shaping up. Then other trailers for the episode strongly hinted at [[spoiler: Bill getting Cyber-converted]], the '''third''' twist of the episode and the ultimate {{Cliffhanger}}! About the ONLY major development not spoiled, partially because the relevant scene was left off of the earliest preview copies, was that [[spoiler: the story led up to the Twelfth Doctor being fatally wounded and facing regeneration — though he managed to put it off through the Christmas Episode that followed]]. Moffat, [[spoiler: John Simm himself]], and many, many reviewers and fans were vocal about how badly this storyline was spoiled.

** By comparison, the BBC did a '''lot''' of this for the final three episodes of Series 9. The press releases and official trailer for [[Recap/DoctorWhoS35E10FaceTheRaven "Face the Raven"]] revealed that the antagonist was [[spoiler: Ashildr/Me]] and strongly suggested that [[spoiler: Clara Oswald would be KilledOffForReal]]; there were fans who believed the second part '''had''' to be more misdirection and that somehow [[spoiler: ''the Doctor'' would bite the dust in the Tonight Someone Dies plot]], but no. The press release for [[Recap/DoctorWhoS35E11HeavenSent "Heaven Sent"]] revealed [[spoiler: the Doctor returning to Gallifrey at last]], which in the episode is part of both TheReveal and the {{Cliffhanger}}. And press releases, trailers, '''and''' photos for [[Recap/DoctorWhoS35E12HellBent "Hell Bent"]] (plus the synopsis for the followup ChristmasEpisode [[Recap/DoctorWho2015CSTheHusbandsOfRiverSong "The Husbands of River Song"]]) revealed that [[spoiler: Ashildr/Me and Clara turn up, the Doctor temporarily becomes a Villain Protagonist, and he doesn't get Clara back as a companion]] in that SeasonFinale. This is especially odd given that up to that point they'd done a good job of ''avoiding'' this trope, such as hiding that [[spoiler: Davros -- both as his usual self and as a boy --]] was featured in the [[Recap/DoctorWhoS35E1TheMagiciansApprentice season]] [[Recap/DoctorWhoS35E2TheWitchsFamiliar opener]] and [[spoiler: the aforementioned Ashildr/Me]] was central to the StoryArc, and having no Next Time teaser at the end of [[Recap/DoctorWhoS35E7TheZygonInvasion "The Zygon Invasion"]], only featuring the villains in the official trailer for [[Recap/DoctorWhoS35E8TheZygonInversion "The Zygon Inversion"]] to preserve suspense over the OurHeroIsDead {{Cliffhanger}}.
** Series 10 was '''even worse''' regarding its two-part SeasonFinale "World Enough and Time"/"The Doctor Falls". First, one of the very first plot points the BBC revealed was that the original Mondasian Cybermen would appear when the former episode is mostly spent building up to TheReveal of their presence. Then the second trailer for the season aired at the end of the season premiere [[Recap/DoctorWhoS36E1ThePilot "The Pilot"]] had a shot of [[spoiler:John Simm as the Master]], the '''second''' big twist of "World Enough and Time", which to judge by Creator/StevenMoffat's comments -- including asking an audience at a screening prior to the episode's initial airing on April 15, 2017, to close their eyes before they could see it -- he would rather hadn't been in the trailer at all, considering how {{unexpected|Character}} this appearance was. It wouldn't have mattered if they did, though -- once [[Recap/DoctorWhoS36E10TheEatersOfLight "The Eaters of Light"]] aired, that twist was spoiled '''everywhere''' -- the Next Time preview of [[Recap/DoctorWhoS36E11WorldEnoughAndTime "World Enough and Time"]], the poster for the episode... all for something only revealed in the last few minutes of the episode. The same Next Time trailer heavily implied that [[spoiler: Bill Potts, the primary companion in this season]] would be the mysterious character the Doctor had "pledged to protect" yet would witness the death of that Moffat teased in his pre-air synopsis, when up to that point it was just as likely to be [[spoiler: Missy, of all people]] given how the StoryArc was shaping up. Then other trailers for the episode strongly hinted at [[spoiler: Bill getting Cyber-converted]], the '''third''' twist of the episode and the ultimate {{Cliffhanger}}! About the ONLY major development not spoiled, partially because the relevant scene was left off of the earliest preview copies, was that [[spoiler: the story led up to the Twelfth Doctor being fatally wounded and facing regeneration -- though he managed to put it off through the Christmas Episode that followed]]. Moffat, [[spoiler: John Simm himself]], and many, many reviewers and fans were vocal about how badly this storyline was spoiled.
** The first trailer for the 2017 ChristmasEpisode "Twice Upon a Time" reveals [[spoiler: Bill Potts and the Doctor are reunited]], which ''could'' have been a huge surprise as [[spoiler: she'd just left, seemingly for good, at the end of "The Doctor Falls"]]. To make matters worse, this doubled as a LateArrivalSpoiler for a major twist in "The Doctor Falls" ([[spoiler: Bill restored to human(oid) form]]).

** New mechas are often spoiled in preview. Especially frustrating in two-parts episodes, with current mecha defeated in part one and new mecha saving the day in part two. ''PowerRangersTurbo'' does a very good job of correcting this while adapting.

* Ion TV's airings of ColdCase are particularly bad. They do a "Next on..." clip before each episode, and there's a decent chance it will be a major spoiler. One episode, about an aspiring singer killed in the 50's, featured Lilly confronting a suspect (granted, we don't see them) with song lyrics. Since their significance isn't apparent until the last few minutes, it becomes obvious that the first witness to bring them up (casually, and for no good reason) is the killer. [[spoiler: The lyrics were written the night he died, so only three people knew them: the victim, his aunt who help him write them, and the killer.]]

* The OnTheNext trailers for ''Series/StarTrekTheOriginalSeries'' were terrible about this. Particularly {{egregious}} is [[http://www.youtube.com/watch?v=uU3B_5hVsns the preview]] of "The City on the Edge of Forever", which so effectively summarizes the whole episode that it plays more like a PreviouslyOn than anything else.
* ''Series/StarTrekTheNextGeneration'' could be pretty awful about this too. Perhaps the most {{egregious}} was the trailer for the episode, "The Most Toys" which showed Data being captured by aliens, a woman alien offering to help Data escape, and a man [[spoiler:incinearting the woman with a phaser]]. When the episode aired, the man was the villain of the episode while the woman was his loyal assistant...and was a major character throughout the entire episode, not doing her HeelFaceTurn and getting [[spoiler:zapped [[RedemptionEqualsDeath by her boss]]]] until within the last 5 minutes of the episode.

* ''Series/{{ER}}'': One episode did this badly enough for TVGuide to call them out. The promos for one episode touted the return of Dr. Carter, even showing a brief scene. How long was Carter's actual appearance? Exactly as long as in the promos, using the exact same scene.

** ''TheHub'' had an interesting case. The trailers showed the newly-ressurrected [[spoiler: D'Anna]] telling [[spoiler: Roslin]] that she is a Cylon. Many viewers wondered if it was real or creative editing. As it was revealed, [[spoiler: D'Anna]] ''did'' say that to [[spoiler: Roslin]]. However, she said to to mess with [[spoiler: Roslin]]'s head. In the commentaries of the episode, [[WordOfGod Ronald D. Moore]] expressed great anger that they ruined the joke by putting it in the trailer.

* If their trailers for ''Series/BigTimeRush'' are of any indication, {{Creator/Nickelodeon}} is just plain terrible at making trailers. The hour-long special ''Big Time Concert'' showed various clips of the boys [[spoiler:back in Minnesota, which implied that they had failed in some way and returned home.]] Worse than that were the clips of [[spoiler:the guys reuniting happily, followed by a detailed sequence of them getting kidnapped by Hawk moments before their show, escaping via Carlos's... bravery, and performing at their concert.]] Let's hope the channel never picks up a mystery series, since every trailer would reveal the culprit-of-the-day.[[note]][[spoiler: Yeah... [[HouseOfAnubis about that...]]]][[/note]]

* For ''Series/OneTreeHill'', TheCW did this to themselves with a Season 7 episode. The OnTheNext preview that aired after 7x08 had Brooke's voiceover stating that she thought she could be pregnant. Later, the CW released the clip where she confesses this to Haley before a concert Haley will be playing that night at the town's nightclub. Then the CW releases a promo photo of Brooke drinking at Haley's concert, clearly revealing she ''wasn't'' pregnant.

* Certain seasons of ''SuperSentai'',uch as ''Boukenger'' and ''Gekiranger'', have a nasty habit of showing story spoilers in the "next episode preview" at the end of each episode.

** Series 10 was '''even worse''' regarding its two-part SeasonFinale "World Enough and Time"/"The Doctor Falls".
