Avatar: The Last Airbender (abbreviated as ATLA), or simply Avatar, is an American multimedia franchise consisting of two animated television series, a live-action film, comics, books, video games, home media, and soundtracks. The franchise began with the animated television series Avatar: The Last Airbender, which aired on Nickelodeon from 2005 to 2008. The series is set in an Asian-inspired[1] fantasy world in which some people can telekinetically manipulate (or "bend") one of the four classical elements: air, water, earth, or fire. Only the titular "Avatar" can bend all four elements and is responsible for maintaining balance in the world.[2][3] Since its original release, Avatar has developed into a franchise spanning works in various media. A sequel animated television series, The Legend of Korra, aired on Nickelodeon from 2012 to 2014 and has since expanded into its own sub-franchise. The storylines of both animated series have been continued in comic book form.[4][5] Other franchise tie-ins include novelizations, art books, companion books, video games, and home media releases. In 2010, the original animated series was adapted into a live-action film titled The Last Airbender. The film itself spawned a novelization series, two graphic novels, two video games, a soundtrack album, and DVD and Blu-ray releases. In February 2021, Nickelodeon announced the creation of Avatar Studios, "a division designed to create original content spanning animated series and movies based on the franchise's world." The original creators and executive producers Michael DiMartino and Bryan Konietzko will run the studio as co-chief creative officers, with an animated theatrical film set to start production in 2021 as its first release. A live-action remake of the original series, produced by Netflix, began development in 2019. Originally set to involve DiMartino and Konietzko, creative differences resulted in the pair leaving during production of the first season.
