The movie "Atari: Game Over" began airing on Xbox last year.

A new documentary explores the decline of video game giant Atari and the secret dumping of its  "E.T." game in a New Mexico landfill. That's where hundreds of copies of the game were unearthed last year.

In 1982, “E.T.: The extra terrestrial” was thought of by many as the worst video game of all time. But when hundreds of copies of it were dug out of an Alamogordo dump, E.T. received a new kind of notoriety. One of the copies was added to the Smithsonian's videogame history collection. A museum in Rome even opened an exhibit on the dig that includes dirt from the landfill. 

The movie "Atari: Game Over" began airing on Xbox last year and was released on Netflix this week. It also will air on Showtime on later this month.
