On what date did Avatar: The Last Airbender first air in the United States?

The story behind the answer

Avatar: The Last Airbender first aired in the United States on February 21, 2005. Nickelodeon launched the animated series with its first two episodes, “The Boy in the Iceberg” and “The Avatar Returns,” presented together as the premiere event.

The series was created by Michael Dante DiMartino and Bryan Konietzko. Its story follows Aang, the last airbender and current Avatar, as he travels with Katara, Sokka, and later other allies to end the Fire Nation’s century-long war. The show’s world is divided among four cultures associated with air, water, earth, and fire.

A common mix-up is confusing the original U.S. premiere with later international broadcasts, DVD releases, or the 2010 live-action film. Another nearby date is March 17, 2006, which marked the U.S. premiere of Book Two: Earth, the animated series’ second season. The original series eventually ran for three seasons and concluded in 2008.
