The O.J. Simpson murder trial is once again in the headlines thanks to “The People v. O.J. Simpson: American Crime Story" TV series. Now, some of the trial's key figures are seeing a payday once again from the renewed interest.

Kato Kaelin -- a high-profile witness who was a guest at Simpson's home on the night he was accused of murdering Nicole Brown Simpson and Ron Goldman -- is now marketing his own line of clothing called "Slacker Wear."

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.

Former Los Angeles Police Department officer and Simpson trial star witness Mark Fuhrman has seen his book about the trial sell more copies in the past few months than in the past five years combined.

"Across the board we see that most of these books are selling between eight and 10 times what they were selling before the series aired," Sara Nelson, editorial director of books and Kindle at Amazon.com, told ABC News.

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.”

“The People v. O.J. Simpson: American Crime Story" has also put together different pieces of pop culture, including Robert Kardashian, a Simpson attorney and the father of the Kardashian reality-TV family, played by David Schwimmer, who starred as Ross on "Friends."

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."
