How many copies of the notorious E.T. game for the Atari 2600 did Atari end up selling?

Atari ended up selling approximately 1.5 million copies of the notorious E.T. game for the Atari 2600. Despite the game's negative reception and the subsequent urban legend surrounding its mass burial, the initial release in December 1982 saw a surge in sales due to the popularity of the movie. However, the game's poor gameplay and critical reception led to numerous returns and unsold inventory. Ultimately, Atari's financial woes and the video game market crash in 1983 contributed to the excess inventory and the ultimate discontinuation of the game, making it one of the most infamous video game releases in history.
