Key Figures in O.J. Simpson Trial Cash in Amid 'The People v. O.J. Simpson' TV Success

Everything from books to clothing related to the trial are for sale.

On eBay, the vintage Versace suit Kaelin supposedly wore on the witness stand during the 1996 trial recently sold for nearly $4,000, two to three times its original value.

Kaelin is not the one, however, bringing that money home. Kaelin told ABC News he borrowed the suit to wear to the trial and the person from whom he borrowed it sold it for the profit.

Sales for "The Run of His Life: The People v. O.J. Simpson," the Jeffrey Toobin-authored book on which the TV series is based, are up 900 percent.

"This story combines everything that obsesses the American people," Toobin told ABC news. "It has sex. It has race. It has sports. It has Hollywood and the only eyewitness is a dog.

"What more could you ask for in a story.”

For some of the stars of the trial, though, seeing it rebooted for a new millennium has been painful.

"For me, it is reliving a nightmare," Simpson prosecutor Marcia Clark told "The View." "You know, it's just awful. Every bit of it is just awful and hard for me."
