"Avatar: The Last Airbender (also known as Avatar: The Legend of Aang)[1] is an Emmy award-winning American animated television series that aired for three seasons on the Nickelodeon television network and on Nicktoons Network. The show is set in an Asian-influenced world[2] of martial arts and elemental manipulation; the series follows the adventures of the main protagonist Aang and his friends, who must save the world by defeating the Fire Lord and ending the destructive war with the Fire Nation.[3][4] In the series' terminology, each episode is referred to as a "chapter," and each season as a "book."

The show made its debut on February 21, 2005, and the last episodes were screened on July 19, 2008; it is now available on DVD, the iTunes Store, and the Xbox Live Marketplace, as well as its home on Nickelodeon.[5] Michael Dante DiMartino and Bryan Konietzko co-created the series, and serve as executive producers alongside Aaron Ehasz.

Avatar: The Last Airbender was popular with both audiences and critics,[6] garnering 5.6 million viewers on its best-rated showing and receiving high ratings in the Nicktoons lineup, even outside its 6–11-year-old demographic.[4][7] The first series' success prompted Nickelodeon to order second[8] and third[9] seasons. Merchandise based on the series include scaled action figures,[10] a trading card game,[11][12] three video games based on the first,[13] second,[14][15] and third seasons, stuffed animals distributed by Paramount Parks, and two LEGO sets.[16]"
