Avatar: The Last Airbender

Avatar: The Last Airbender is an Emmy award-winning American animated television series that aired for three seasons on Nickelodeon and the Nicktoons Network. The series was created and produced by Michael Dante DiMartino and Bryan Konietzko, who served as executive producers along with Aaron Ehasz. Avatar's setting is in an Asian-influenced world of martial arts and elemental manipulation. The show drew on elements from East Asian, South Asian, and Western culture, making it a mixture of what were previously traditionally separate categories of Japanese anime and Western domestic cartoons.

The series follows the adventures of the main protagonist Aang and his friends, who must save the world by defeating Fire Lord Ozai and ending the destructive war with the Fire Nation. The show first aired on February 21, 2005 and the series concluded with a widely-lauded two-hour television movie on July 19, 2008.

Avatar: The Last Airbender was popular with both audiences and critics, 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. Avatar has been nominated for and won awards from the Annual Annie Awards, the Genesis Awards and the primetime Emmy Awards, among others. The first season's success prompted Nickelodeon to order second and third seasons. The first part of a movie trilogy titled The Last Airbender was released on July 1, 2010, and a live-action reimagining produced by Netflix in partnership with Nickelodeon is due to enter production in 2019.

Merchandise based on the series includes scaled action figures, a trading card game, three video games based individually on each season, stuffed animals distributed by Paramount Parks, and two LEGO sets. The series' popularity spawned a sequel series, titled The Legend of Korra, which takes place seventy years after the original series.
