"Avatar: The Last Airbender" was co-created and produced by Michael Dante DiMartino and Bryan Konietzko at Nickelodeon Animation Studios in Burbank, California. Animation work was done by the Korean animation studio DR Movie. According to Bryan Konietzko, the program was conceived in the spring of 2001 when he took an old sketch of a balding, middle-aged man and re-imagined the character as a child. Konietzko drew the character herding bison in the sky, and showed the sketch to Mike DiMartino. At the time, DiMartino was studying a documentary about explorers trapped in the South Pole.
Konietzko described their early development of the concept: The co-creators successfully pitched the idea to Nickelodeon VP and executive producer Eric Coleman just two weeks later.
The show was first revealed to the public in a teaser reel at Comic-Con 2004, and started show the episodes from 21 February 2005. In the United States, first two episodes of the series were shown together in a one-hour premiere event. A second twenty-episode season ran from 17 March 2006 through 1 December. A third and final season, beginning September 21, 2007, featured twenty-one episodes rather than the usual twenty. The final four episodes were packaged as a two-hour movie.
"Avatar" is notable for borrowing extensively from Asian art and mythology to create its universe. The show's character designs are heavily influenced by anime as well as Chinese art and history, Hinduism, Taoism, Buddhism, and Yoga. Traditional East Asian calligraphy styles are used for nearly all the writing in the show. For each instance of calligraphy, an appropriate style is used, ranging from seal script (more archaic) to clerical script. The show employed a cultural consultant, Edwin Zane, and calligrapher Siu-Leung Lee as consultants for the show's cultural influences.
The choreographed martial art bending moves were profoundly affected by Asian cinema. In an interview, Bryan revealed that, "Mike and I were really interested in other epic 'Legends & Lore' properties, like Harry Potter and "Lord of the Rings", but we knew that we wanted to take a different approach to that type of genre. Our love for Japanese anime, Hong Kong action and kung fu cinema, yoga, and Eastern philosophies led us to the initial inspiration for "Avatar"."
All music and sound used in the series was done by Jeremy Zuckerman and Benjamin Wynn, who form "The Track Team". They made use of a wide range of different instruments (such as the guzheng, pipa and duduk) to compose a background music that fits into the world.
The term "Avatar" comes from the language of Sanskrit, one of the most ancient languages of India. The word "Avatāra", (Sanskrit: ), which means "descent"; its roots are "ava" means "down," and "tri" means "to pass." In the Hindu scriptures, "avatara" signifies the descent of Divinity into flesh. One who attains union with Spirit and then returns to earth to help humanity is called an avatar. The Chinese characters that appear at the top of the show's title card mean "the divine medium who has descended upon the mortal world."
When Aang was young, he unknowingly revealed that he was the Avatar when he chose four toys out of thousands, each of which were the childhood toys of the previous Avatars. In Tibetan Buddhism, there is a similar test for reincarnations of a Tulku Lama. In "Magic and Mystery in Tibet", Alexandra David-Neel writes that "a number of objects such as rosaries, ritualistic implements, books, tea-cups, etc., are placed together, and the child must pick out those which belonged to the late "tulku", thus showing that he recognizes the things which were "theirs" in their previous life." Each successor is expected to show signs of continuity with the previous Avatar, such as being born within a week of the death.
"Avatar" draws on the four classical elements common to many ancient philosophies for its bending arts: Water, Earth, Fire and Air. Although each has its own variation, most ancient philosophies incorporate these four elements in some way. Examples include the classical Hindu, Buddhist, and Greek elemental traditions. In the show’s opening, each element is accompanied by two Chinese characters: an ancient Chinese seal script character on the left representing the element being shown and a modern Chinese character on the right describing some feature of the element.
