A New York Times article from 1983 reported that Atari cartridges of "E.T. The Extraterrestrial" were dumped in the landfill in Alamogordo.
Fuel Entertainment is producing a documentary about the search.
The videogame's commercial failure was partially responsible for the demise of Atari in the early 1980's.
The contents of the "Atari Grave" have become urban legend, with blog posts speculating about millions of cartridges and other Atari projects buried there. A spokeswoman for Atari says the company changed hands many times since 1983 and does not know what is buried there.
