Full name: Adventure Time with Finn and Jake.A franchise centered on a popular cartoon on Cartoon Network, created by one Pendleton Ward, later spawning an Expanded Universe in other media.The series gained its start in 2008 when Ward created a short cartoon to be showcased on Nickelodeon's Random Cartoons. When it wasn't picked up and the rights returned to Pen, he uploaded the short on YouTube where it went viral. Cartoon Network soon took notice of this and offered to turn it into a full series (even ordering two seasons right from the get go). CN gave the show a huge promotion push and even previewed episodes before the show properly premiered on April 5, 2010. It has since become one of the Network's most watched animated series.The show follows the adventures of boy hero Finn (named Pen in the pilot) and his talking, shape-shifting dog, Jake, in the strange, bizarre and very dangerous world of Ooo. The setting is gradually revealed to be Earth after an apocalyptic event known as the "Mushroom War". The event radically transformed the landscape and brought back magic to the world, leading to the creation of all kinds of bizarre creatures and entities. Finn is supposedly the only living pure human left in this world, having been adopted by Jake's family after they found him as a baby. As such the two consider themselves brothers and go on many adventures through the land. Add a colorful cast of characters including (most notably) the boys' feudal patron Princess Bubblegum, ruler of the nearby Candy Kingdom; Ice King, a deranged elemental wizard and increasingly Friendly Enemy of the two who obsessively kidnaps Princesses; and Marceline, a hipster self-proclaimed Vampire Queen, and you have one of the most unique and interesting pieces of fantasy to ever grace the genre.To say the show is weird is an understatement, and it is known for Mood Whiplash and Cerebus Rollercoaster into some horrific and/or tragic territory (it was given the TV-PG rating for a reason). Despite or more likely because of this it has reached a wide audience, and due to this popularity has branched out into other forms of media as well.
