''Adventure Time'' (aka ''Adventure Time with Finn and Jake'') started as a seven-minute short created by Creator/PendletonWard. Originally produced to be a part of "Random! Cartoons" on {{Nickelodeon}}, it was meant to premiere in Fall of 2007. The [[VarietyShow animated variety show]] was delayed until December 2008, but the short was previewed in 2006. As is the way of things, the previewed short was leaked unto the Internet and quickly went viral.

Why? Because it's [[WidgetSeries really]] [[DerangedAnimation frickin']] [[GainaxEnding weird]], that's why.

Both the original short and subsequent series feature the adventures of two best friends: [[ExpositoryThemeTune Jake the Dog and Finn the Human]] (Pen the Human in the original short). Their adventures are nonsensical, crazy, and bear more resemblance to a group of kids playing with action figures than a coherent story... which is probably why it's [[RuleOfFun so dang fun]].

Much like ''WebAnimation/HomestarRunner'', it's sort of a cross between a children's show and a parody of a children's show. These elements are still very much present even after the show [[CerebusSyndrome took a turn for the darker]]. {{Nickelodeon}} passed on making it into a series, but their rival Creator/CartoonNetwork saw its potential and ordered two full seasons off the bat. It started airing on April 5 2010 to the delight of 2 million viewers.

As of now the show has begun its sixth season, with a seventh confirmed to be in production.

Thanks to the massive success of the series, Creator/KaboomComics is publishing a [[ComicBook/AdventureTime comic book adaptation]], currently written by [[Webcomic/TheAdventuresOfDrMcNinja Christopher Hastings]]. It's set in its own AlternateContinuity but is still just as crazy weird as its TV incarnation. Also thanks to the media, it has allowed other characters to get their chance to shine in their own mini series, which are as follows:

* ''[[ComicBook/AdventureTimeMarcelineAndTheScreamQueens Marceline and the Scream Queens]]'' - Written by [[Webcomic/OctopusPie Meredith Gran]] and starring Marceline and Princess Bubblegum as they go on a world tour through Ooo with Marcie's band, ''The Scream Queens''.
* ''ComicBook/AdventureTimeWithFionnaAndCake'' - A comic which, of course, stars the gender-swapped alternate counterparts of the main characters. Written by character designer Natasha Allegri.
* ''Candy Capers'' - A comic that stars Peppermint Butler and Cinnamon Bun as they're charged by Bubblegum to figure out who kidnapped Finn and Jake. Written by [[Webcomic/JohnnyWander Yuko Ota and Ananth Panagariya]] with art by Ian [=McGinty=].
* ''The Flip Side'' - Finn and Jake wind up in a "reverse adventure", where they have to do the opposite of what they signed up for.
* ''Banana Guard Academy'' - A comic about Root Beer Guy's adventures in the Banana Guard. Written by head writer Kent Osborne with art by [[Webcomic/{{Sakana}} Mad Rupert]].
* ''Marceline Gone Adrift'' - The second ''Adventure Time'' comic written by Meredith Gran. also starring Marceline and Bubblegum. Marceline goes on a rampage throughout Ooo, and Bubblegum accidentally shoots Marceline into space and strips her of her powers, forcing Bubblegum to travel into space to find her.

The series also started getting [[ComicBook/AdventureTimeGraphicNovels graphic novels]] beginning in 2013, written by [[Webcomic/GirlsWithSlingshots Danielle Corsetto]] and Kate Leth with art by Zachary Sterling. So far four volumes have been released.

Likewise it has gotten a few video games. (The trope page for ''Hey Ice King!'' and ''Explore the Dungeon'' can be [[VideoGame/AdventureTime found here]]). ''Battle Party'' has its own page.

* ''Adventure Time: Hey Ice King! Why'd You Steal Our Garbage?!'': Released in 2012 for both the NintendoDS and [[Nintendo3DS 3DS]], developed by WayForwardTechnologies and has an original plot written by Pendleton Ward himself
* ''Adventure Time: Explore the Dungeon Because I DON'T KNOW!'': Released in 2013 for the 3DS, WiiU, {{Xbox 360}}, {{Playstation 3}}, and PC. Pen once more wrote the story for it and has stated the game contains "a huge reveal" that will be part of the series canon.
* ''VideoGame/AdventureTimeBattleParty'': A free-to-play browser MOBA.
* ''Adventure Time: The Secret of the Nameless Kingdom'': Released in 2014 for the PS3, Vita, Xbox 360 and the 3DS.

On October 2nd, 2014, Pendleton Ward [[http://www.rollingstone.com/tv/features/adventure-time-the-trippiest-show-on-television-20141002 announced to Rolling Stone]] that he had stepped down from his position as the showrunner of the series. He claims that working on such a beast of a project just really wore him out. He continues to remain as a storyboard artist, script writer, and the voice of Lumpy Space Princess.

A miniseries has been announced and not too long after, so was a '''''[[http://deadline.com/2015/02/adventure-time-film-cartoon-networks-1201383129/ theatrical movie]]'''''. Needless to say, there was much rejoicing amongst the fandom.
