I've got a perfect platform to kind of be reintroduced to the organization that catapulted me into notoriety and stardom. Do you sometimes look at what's going on today and say, I lost my crown because of that, really? People are now releasing things to make a career. It's true. That's crazy. To think that, oh, you can look at a scandal and think that would be good for your career. Where for me it took every ounce of credibility and talent that I had and wiped it out. Reporter: It's been a long and emotional road back for Vanessa, who decades ago was unsure whether to fight for her title. The heightened spectacle and circus of it all was kind of crazy. I had people that were saying, fight for the crown, fight for the crown. And people chanting, don't give it up, don't secede. Fight, Vanessa, fight! Reporter: Back then her parents, especially her mother, didn't want her to give up. She felt the injustice was having performed my duties and excelled in everything that I was asked to do, plus doing 50% more of appearances that were not scheduled because I was the first african-american miss America. It was really hard for my mom when I decided to resign. She felt that I shouldn't have to, she felt it was the wrong moves. She remembers the pageant did not come to my support. They felt I needed to resign. She harbored a lot of resentment. Reporter: Meanwhile Vanessa was unaware of what her parents, who were still living in her childhood home, were epdo you remembering. They refused to change their phone number so people would call, prank calls, really try to hurt their feelings. People would drive by the house and beat things and yell stuff at the house. There was graffiti that was written on our local a and P in my home down that was derogato derogatory. They took home the sign "Home of New York miss America." An incredible amount of shame and humiliation. Reporter: But they survived the storm. Their mother/daughter bond so ago that Vanessa wihe tn 20-year-old college junior, became the first african-american to win the title. Did you understand the significance of being theirst n-american woman? No. To be miss America? I didn't realize how big it would be. Whas touring, older black women thought they'd never see it inheir T lifetime. Me psoeople dwoul cry. Reporter: But nearly 11 months into her N, scaal nd erupted. Racy nude photos she had posed for years earlier were sold without her permission to "Penthouse" magazine. What's going on but I'm sorry. We have no what's going to happen. I was stupid and I took some pictures and app do feel that I should return. So the people that harbor the resentment, I understand it. But realize that all those people that were part of the old guard are no longer there. And there might be some more surprises. We'll see. Reporter: For "Nightline," I'm robin Roberts in New York.
