Lead prosecutor Marcia Clark became a household name during the 1994-1995 trial, which was broadcast into the living rooms of everyday Americans.
By October 1994, a "roving band of reporters" surrounded Clark as she left the courthouse one day, The New York Times reported at the time.
The Times noted that Clark made efforts to change her appearance in an apparent effort to seem more sympathetic to the jury. During the trial, she started sporting "shorter, better-kempt hair that framed her face, warmer and lighter-colored dresses with softer fabrics, more jewelry," according to The Times.
Clark scored a $4.2 million book deal by the end of the trial. These days, Clark describes herself on her Facebook page as the author of the Rachel Knight series about a district attorney in Los Angeles.
"Writing novels and being in the courtroom — it's a storytelling job, no matter how you look at it," Clark told Oprah Winfrey in 2013. "It's the same thing."
Clark — who's played by Sarah Paulson in the FX show — recently spoke to the New York Post about the dramatization of the O.J. trial.
"I could sit back and appreciate the brilliance of the performers, but I kept coming back to the idea that two people are dead. Ron Goldman and Nicole Brown Simpson. It was pretty hard sitting through the first two episodes," Clark told the Post. "Whatever you think of [OJ] Simpson, the murderer walked away. No one was brought to justice."
