On what date did The Legend of Korra first premiere in the United States?

The Legend of Korra first premiered in the United States on April 14, 2012. Its television debut began with “Welcome to Republic City,” the opening episode of Book One: Air.

The series was created by Michael Dante DiMartino and Bryan Konietzko as a sequel to Avatar: The Last Airbender. It follows Korra, the next Avatar after Aang, as she leaves the Southern Water Tribe and travels to the technologically advanced Republic City to learn airbending from Tenzin, Aang’s son.

There is a small release-history detail that often causes confusion. The first two episodes were made available online on March 24, 2012, before the television broadcast. That online preview was not the U.S. television premiere, however. Nickelodeon’s official broadcast premiere remained April 14, 2012. The series eventually ran for 52 episodes across four books, concluding in December 2014.
