History ScheduleSlip / AnimeAndManga

* ''Manga/HibikiNoMahou'' was published in a monthly magazine for twelve years... but due to Rei Izumi's health-issues, in this time it only released 29 chapters (34 if one includes the bonus-chapters). It took seven years between the release of volumes 2 and 3.

* ''Manga/JoJosBizarreAdventure'' had its 3rd arc licensed by Viz. It was scheduled to run over 16 volumes, which should've been a layup. Instead, the 11th volume was delayed from August 2008 to April 2009, for ''eight months'', solely because of a scene where the villain, Dio, read pages from a book while threatening to kill Jojo. Why was this a problem? Well, in the manga, this book was just unreadable scribbles... but in the second OVA series based in this arc, writers copy-pasted text from the Qur'an in without knowing what it was, and the resulting protests caused Viz to halt all sales of ''all'' Jojo-related material, manga and anime alike, until they could be checked for other such errors.
** Note that the actual manga series itself is from the We-Couldn't-Make-This-Up department but because of another reason. Hirohiko Araki, the author, has never missed a deadline in all 27 years of drawing Jojo (over 100 volumes and counting).

* ''Manga/HunterXHunter'', from Creator/YoshihiroTogashi, the author of ''Manga/YuYuHakusho'', was featured regularly in ''Magazine/ShonenJump'' for several years. Nowadays the series is on hiatus much more than it is not (picking up the FanNickname" Hiatus × Hiatus" in the process), with roughly one collected volume coming out every year and a half or so (JC titles typically put out six or seven volumes in that same amount of time). Delays have been attributed to [[IncurableCoughOfDeath illness]], to the author being [[WagTheDirector kiiiiinda hard to work with]] or to him and his [[Creator/NaokoTakeuchi wife]] spending time with their children. The fact that unlike almost all mangaka he works without assistants (aside from occasionally his wife, [[Manga/SailorMoon who's a very successful mangaka in her own right]]).

** The ''Anime/RebuildOfEvangelion'' movies count as well. The entire series was supposed to have finished up back in '''2009'''. The current target release date for the final installment? ''Winter 2015''. Well, that time has come and gone, and now no one knows when it's coming out.

* ''Manga/DGrayMan'' has experienced several stops in production due to the author falling ill. After a hiatus in 2009, the series returned with a fifty page chapter... and another hiatus. However, from November on, it started running monthly rather than weekly.

** The ''Anime/RebuildOfEvangelion'' movies count as well. The entire series was supposed to have finished up back in 2009. The current target release date for the final installment? "''Winter 2015''".

* ''VideoGame/PrettyRhythhAuroraDream'' was supposed to premiere on April 2nd, 2011, but due to the Tohoku earthquake and tsunami, the show premiered a week later.

* Creator/KentaroMiura, the creator of ''Manga/{{Berserk}}'', is practically ''legendary'' for this. When he is actually on schedule, new tankobon volumes of the manga come out roughly twice a year, not out of the ordinary considering the magazine it's published in, but he takes hiatuses a lot – most notoriously, he ended one hiatus to start another one just ''two months'' later. and Berserk is a ''chapter-a-month series''. These breaks are [[http://berserk-confessions.tumblr.com/post/18084538410/i-have-a-lot-of-respect-for-kentaro-miura-after likely necessary]] to stave off [[CreatorBreakdown breakdowns]].

* One reason for the AdaptationInducedPlotHole and somewhat abrupt ending of ''Manga/FruitsBasket'''s anime while the manga was still in progress? NatsukiTakaya broke her left arm. Her ''drawing'' arm.[[note]] The ''other'' reason for the abrupt ending was that, because the anime was produced while she was recuperating, Takaya was able to be very involved in the anime's production. This resulted in a lot of micromanagement and meddling, which thoroughly pissed off director Akitaro Daichi. Takaya didn't appreciate the pushback.[[/note]]

* ''Manga/HunterXHunter'', from Creator/YoshihiroTogashi, the author of ''Manga/YuYuHakusho'', was featured regularly in ''Magazine/ShonenJump'' for several years.

* After an almost-three-year hiatus from June 2010 to March 2013, the ''BlackLagoon'' series has finally started releasing new chapters. But as of February 2014, there have been no new releases, except for May 2014 when Volume 10 of the manga was released... which not-so-coincidentally covers up to all the currently released chapters (87 as of this writing).

** The [=OVAs=] also followed suit in what it seems to be a staple in the franchise, the first three episodes had just a few months between them (typical for a lavishly-animated OVA). From the 4th onward, the delays would just get longer and longer as Satelight was having a hard time producing the episodes all by themselves. After a year and half without releasing anything, Satelight passed the baton to Madhouse and it looked like they would keep up the pace, and they did... up to the 7th episode, another year and few months (and many rumors that Madhouse just dropped the series) is what it took for the 8th episode to get a release date; the series finally finished with the release of the 10th episode in late December 2012, nearly seven years after the series began.

* ''Manga/NausicaaOfTheValleyOfTheWind'' was originally started in 1982 solely to get funding for the film (as people with money would not back an anime movie ''not'' based on a manga when Miyazaki was still a relative unknown). The final story was 7 volumes long (about 3½ years for a monthly series, and these volumes were shorter than most), but it did not finish until ''1994''. This is because Miyazaki would take long hiatuses to [[CastleInTheSky direct]] [[MyNeighborTotoro some]] [[KikisDeliveryService more]] [[PorcoRosso movies]]. The end result of this is that the story in the ''Nausicaä'' movie only covers the first volume and a half of the manga.

** Don't forget the ''RebuildOfEvangelion'' movies. The entire series was supposed to have finished up back in 2009. The current target release date for the final installment? "''Winter 2015''".
* ''Manga/SaintSeiyaNextDimension'' suffered a number of these due to the creator becoming really sick, the switch to all-color, and Editors delaying it on purpose due to ''SaintSeiyaTheLostCanvas''.
* The series of light novels of ''LightNovel/HaruhiSuzumiya'' have suffered as a whole: it had a hiatus of four years in between the releases of the ninth volume (April 2007) and the tenth and eleventh ones (May 2011). That, and the fact that the author once confirmed that the eleventh novel was not going to be the ''last'' volume...

* ''Manga/JoJosBizarreAdventure'' had its 3rd arc licensed by Viz. It was scheduled to run over 16 volumes, which should've been a layup. Instead, the 11th volume was delayed from August 2008 to April 2009, for ''eight months'', solely because of a scene where the villain, Dio, read pages from a book while threatening to kill Jojo. Why was this a problem? Well, in the manga, this book was just unreadable scribbles... but in the first anime adaptation, writers copy-pasted text from the Qur'an in without knowing what it was, and the resulting protests caused Viz to halt all sales of ''all'' Jojo-related material, manga and anime alike, until they could be checked for other such errors.
** Note that the actual manga series itself is from the We-Couldn't-Make-This-Up department but because of another reason. Hirohiko Araki, the writer and artist, has never missed a deadline in all 25 years of drawing Jojo (over 100 volumes and counting).
* ''Manga/MahouSenseiNegima'''s author, KenAkamatsu, takes breaks lasting from a week to upwards of three weeks every now and then, claiming to be doing research. While he's almost as famous for his ShownTheirWork moments as he is for inducing [[TropeOverdosed trope overdose]], [[MemeticMutation a lot of fans joke]] that his "research time" is spent [[MaleGaze researching his wife]]. In truth, as he has gotten older his drawing speed appears to have decreased and thus it takes slightly more than a week to draw one week's chapter, leading to a rough schedule of 3-4 chapters and then a break.

* Newer fans of ''{{Guyver}}'' tend to think this is what happens with Yoshiki Takaya however he consistently puts out one book a year and has never once put out an issue each month for an entire year. He did once have a hiatus to finish up another of his works from before ''Guyver''.
* One reason for the AdaptationInducedPlotHole and somewhat abrupt ending of ''FruitsBasket'''s anime while the manga was still in progress? Natsuki Takaya, the creator, broke her left arm. Her ''drawing'' arm.[[note]] The ''other'' reason for the abrupt ending was that, because the anime was produced while she was recuperating, Takaya was able to be very involved in the anime's production.

* DigitalMangaPublishing is ''infamous'' for this, as it can take ''years'' for them to release volumes. It's gotten to the point that many have assumed that they lost the licsenses when they actually haven't.
** MediaBlasters is pretty much this as well when it comes to their anime releases. A good portion of them end up never actually coming out (''SayonaraZetsubouSensei'' for example).

* From the We-Couldn't-Make-This-Up department: ''Manga/JoJosBizarreAdventure'' had its 3rd arc licensed by Viz. It was scheduled to run over 16 volumes, which should've been a layup. The 11th volume was delayed from August 2008 to April 2009, ''eight months'', and nearly derailed the entire run. Reason? Viz was dealing with protests from MoralGuardians about one panel in volume 10, Dio reading a book... which showed absolutely zero legible text. And why was this a problem? Because in the first ''anime'' adaptation, this page contains Arabic text. Yeah. That's it. Eight months lost to this.

* The second season of ''LightNovel/HaruhiSuzumiya'': Announced back in 2007, said to be released fall 2007/spring 2008, eventually released summer ''2009''.
** Don't forget the light novels. The first was released in June 2003 and the ninth and latest one was April 2007. As of this writing, they eventually released the tenth book and eleventh in May 2011. However, the eleventh novel was confirmed to not be the ''last'' volume.
