!!Trivia tropes:
* ActorAllusion: Principal Franklin's daughter Emily was named after [[Series/StarTrekVoyager Tim Russ]]' real-life daughter who is also a fan of the show.
* AdoredByTheNetwork: Nickelodeon will often show nothing but this show and ''SpongeBob'' all day and treat it better than the others, though it has been replaced somewhat with ''Victorious''.
* FanNickname: Some people who don't ship the Sam/Freddie relationship have called the the second half of Season 4 ''iSeddie'' or ''iSam'', due to the Seddie shipping arc taking up 4 out of the 9 episodes filmed and Sam and Freddie together continually taking the A-Plot with Carly pushed down to the B-plot or C-plot in pretty much every episode, especially as some episodes had Carly completely absent or in a plot completely away from the rest of the main cast. Many consider it a {{Spinoff}} or ContinuityReboot instead of a new season with characters who look, sound and share the same names, but aren't the same characters from previous seasons.
** Ironically, Sam was eventually given a spin-off show called ''SamAndCat''.
** The imaginative, pejorative names of "Sucky" and "Cruddie" for Seddie and Creddie respectively.
* RoleAssociation:
** [[Series/DrakeAndJosh Megan Parker & Crazy Steve]] are Carly & Spencer Shay.
** Familiar sci-fi characters become faculty members! [[Series/StarTrekVoyager Tuvok]] as Carly's principal and [[AustinPowers Frau Farbissina]] as Ms. Briggs.

** In ''iReunite With Missy'', you might recognize Missy if you've seen Gwen from the live-action ''WesternAnimation/{{Ben10}}'' film and young Jean Grey from [[Film/XMenTheLastStand X3: The Last Stand]], it's Haley Ramm. Schneider took the actress to play the role of Carly's best friend because Ramm and Cosgrove are also real-life best friends.
** In ''iFind Lewbert's Lost Love'', the woman in the hall is Creator/LaraJillMiller, who voiced Kari in the English dub of DigimonAdventure02 and [[TheLifeAndTimesOfJuniperLee Juniper Lee]].
*** Lewbert's Lost Love was The Janitor's love, "Lady" in ''Series/{{Scrubs}}''.

** Taran Killam (once a cast member on Nickelodeon's ''TheAmandaShow'', now a repertory player on ''SaturdayNightLive'' and was once ''Series/{{MADtv}}'''s youngest cast member at only 19 years old) gets a small role as a Secret Service agent in iMeet the First Lady. You probably didn't notice him due to the episode's other guest star, ''Michelle freakin' Obama!''
** In some commercials for the show's merchandise, Carly & Sam are represented by [[Series/ShakeItUp Rocky Blue]] and [[Series/ANTFarm Lexi Reed]], respectively.
** EmmaStone had a cameo in one of the later episodes of the show.
** What was [[Series/FallingSkies Hal Mason]] doing in Seattle, making out with Carly?

* IronyAsSheIsCast: Miranda Cosgrove has a [[http://storage.people.com/jpgs/20091014/20091014-750-72.jpg talent in drawing]]. But as Carly, she can't even make a good drawing of a bunny.
* LyingCreator: The week before the "iSaved Your Life" episode aired, a promo aired showing Carly/Freddie kissing. DanSchneider, in an effort to calm the shippers of the Sam/Freddie pairing, implied it might not be what it appeared. Cue the episode, where they ended up kissing 7 or 8 times, and it was as it appeared.
** He posted a picture of Carly and Freddie kissing as a tease for ''iSpeed Date''.. then cut the kiss out later because of a kiss would have impacted on the story of ''iSaved Your Life''. The kiss was likely to have been removed from the script before filming because they would have done the 2nd script already, so he basically created a blatant piece of lying ShipTease for no reason.
* NotScreenedForCritics: Like every teen and children's show, ''{{iCarly}}'' is not shown to critics. In combination with closed set filming and tight control on information being passed around, Dan managed to keep the Sam/Freddie plot in ''iOMG'' ''and'' every episode in the subsequent story arc a secret.
* PeripheryDemographic: Each season skewed older than the last as word got out among adults and the original target cohort grew up.
* [[PromotedFanboy Promoted Fangirl]]: See GuiltyPleasure above: Emma Stone got a cameo role in an episode.
** In-universe example: Gibby is a '''huge''' fan of the British boy band OneDirection and got to sing with them as a ploy to get their lead singer to stop pretending to be sick so he could keep staying at Carly's and be nursed by her.
* RealLifeRelative: Gibby (Noah Munck)'s brother Guppy is played by his real-life brother Ethan.
* ScrewedByTheNetwork: After season three, Nick has taken a decidedly inconsistent approach to the show. It only orders 13 episodes at at time compared to the 26 or so that it was doing in the first three, it airs the show at random times, advertises that the entire season will be played every week, then stops it after 3 episodes, puts on new episodes with little advertising, and then starts putting them on at weird times, such as Wednesday the 28th of December for the second blooper episode, and then 8-9pm New Year's Eve for the iPsycho sequel. Admittedly, Dan Schneider has to take some of the blame, as he seems to have poor time management, which means Nick were only ordering 13 episodes of both iCarly and ''{{Victorious}}'' when they could have fit full seasons in even with the studio split (the two shows share the same studio space, and can't film when the other is filming) taken into account. This odd handling of the show and it's timeslots is one the bigger reasons for the abysmal ratings for Season 5 compared to seasons 2, 3 and 4.
* ShrugOfGod: Ask DanSchneider a question about Seddie or Creddie. It will be a miracle if you get a straight answer back. The more 'intelligent' the question, the less likely he will even respond at all. The dumbest, or least focused questions might get the question thrown back at them in a different way.
* SoMyKidsCanWatch: [[Series/TheWestWing Joshua]] [[SportsNight Malina]] appeared on the show because his children love it.
* ThrowItIn: On iQuit iCarly, Dan Schneider remarks:
--> Listen to how Gibby delivers his line: 'Uh-oh! Looks like trouble off the stern... port... bow.' You'll notice how he seems confused and slows down at the end of that line. The reason? Noah ("Gibby") forgot the line as he was saying it! He couldn't remember how it ended. Later, when I watched it in editing, I felt it played really funny, so I used the take where he forgot the line.
* WhyFandomCantHaveNiceThings: Before Season 3 had started airing, Dan posted a [[http://icarly.wikia.com/wiki/File:40991089.jpg script fragment from a future episode]]. He took it down quickly, but it was reposted on various sites. Naturally, shippers from both sides went nuts, especially on LiveJournal. After heavy criticism about Dan ruining the fandom and the LJ communities with his interaction he quit and deleted his LiveJournal, without warning or notice (meaning the fandom lost alot of interesting interaction with him), and eventually setup his own blog site, which he claimed was for better control, but his first post was about being pissed off with reponses to his script.
* WordOfGod: DanSchneider. Very carefully avoids LyingCreator by using ambiguous meanings, hypothetical, counter-questions in response to questions and shrowding common shipping viewpoints in terms of what "his friends" might think about what's happening. Was very active in the fandom up to the start of Season 3, although not as much now that he's dealing with ''{{Victorious}}'' as well as the 4th season of ''iCarly''.
** Taken to the extreme with his post about the finale iGoodbye. After seeing InternetBackdraft about his failure to make the Seddie pairing canon while he made Creddie canon via a typical LastMinuteHookup, he wrote a blog that could be described in short as "completely inverting the meaning of what just took place on screen" by attempting to claim the LastMinuteHookup, the romantic moment Carly comes up to the studio, takes Freddie by the hand then kisses him just moments before leaving for Italy may have ''actually'' been a platonic 'friendship' kiss. This did not go down well in the fandom, with people calling him out for the BlatantLies, many female viewers were especially upset about the idea that they just go around passionately kissing their male friends to show their friendship. This is a good example of WordOfGod actually making the understanding of what took place on their show ''less clear''. Then again, it was likely deliberate as Dan has the new SpinOff SamAndCat, and he wanted to dangle the potential of the Seddie relationship picking up on that show to get more viewers. Most people in the fandom have simply ignored him and have gone by what took place on screen.
* WhatCouldHaveBeen: The original name of the Carly character was going to be Sam. The female sidekick was going to be called Kira. But they couldn't get the [=iSam=] domain name. So Sam became Carly, and Kira became Sam. This has the curious effect of swapping around the PortmanteauCoupleName of both major ships. The JustFriends Creddie ship would have been known as Seddie, while the JerkAss Seddie ship would have been known as Kreddie. It would have a minor impact on the LesYay Cam ship by changing the name from Cam (Carly/Sam) to Kam (Kira/Sam).
** Dan Schneider originally explored a straight ''DrakeAndJosh'' spin-off as a Miranda Cosgrove vehicle, with Miranda naturally reprising her role as Megan Parker, but ultimately he felt dissatisfied with every idea centered around that concept he could think of. He then explored the idea of a fresh concept and character that was getting closer to ''iCarly'', but centered around a girl who suddenly found herself getting her own variety TV show. He got as far as writing the script for the pilot - and then threw it in the trash, once again being dissatisfied. He then changed the "TV show" to "web show", and things finally started to click.
** A second ''iCarly'' spin-off centered around Gibby (and [[CharacterTitle titled as such]]) had a pilot filmed but was not picked up. As originally envisioned by Dan, it would have ran alongside ''SamAndCat'' and ''{{Victorious}}''.
** In-universe example: If Spencer was born normal, Carly and Nevel would be girlfriend and boyfriend, much to Carly's horror.
* TheWikiRule: Has a very large and active Wikia site located [[http://icarly.wikia.com/wiki/ICarly_Wiki here]].
* WriterRevolt: It's likely that ''iGo Nuclear'' is the result of being forced by ExecutiveMeddling to create an episode with a GreenAesop. See the BrokenAesop entry in the main tropes page to see how it turned out.
* YouMightRememberMeFrom: VictoriaJustice, who played Shelby Marx in "iFight Shelby Marx", previously worked on another Dan Schneider show, ''{{Zoey 101}}''.
