The videotapes were shelved on the Fox studio lot and recently discovered. In a release, Fox breathlessly described the "infamous" interview as "lost — until now."
"Simpson's explosive words finally will be heard, as he answers the questions that gripped a nation during the notorious 'Trial of the Century,'" the network said in a release.
Simpson was acquitted of criminal charges by jurors but found responsible in a subsequent civil trial.
The ghostwritten, fictionalised account of the murders ultimately was published by another company, and a federal bankruptcy judge later awarded rights to the book to Goldman's family to help satisfy a US$38 million wrongful death judgment against Simpson.
The family labeled the book as Simpson's confession, the same description Regan offered in justifying the original publication. In the interview with Regan, Simpson talked about how he would have committed the murders "if he were the one responsible."
The former American football hero served nine years in prison for leading five men, including two with guns, in a September 2007 confrontation with two sports collectibles dealers at a Las Vegas casino hotel.
