"Joan and Melissa were the first people who came out and made it more of a true conversation between star and reporter", E!'s Senior Vice President of production, Gary Snegaroff, remarked to Vanity Fair.

Rivers and Melissa, at the time, both portrayed themselves in the made-for-television drama Tears and Laughter: The Joan and Melissa Rivers Story, which chronicled the aftermath of Rosenburg's suicide. It aired on NBC on May 15, 1994. The next year, she wrote her book Jewelry by Joan Rivers.
