It's a day that shocked the sports world and changed the course of NBA history.  Nov. 7, 1991, 20 years ago today, NBA superstar Earvin "Magic" Johnson told the world that he contracted the HIV virus and was retiring from basketball.  At the time, Magic's announcement seemed like a death sentence, especially because people had so many misconceptions about HIV and AIDS.  In the years following his diagnosis, Johnson has become the face of HIV and an advocate for safe sex.   Today we look back at the day that changed Magic Johnson's career and the way the world viewed HIV.

Announcement that shocked the world – The day Magic Johnson heard he contracted HIV, he could have kept his mouth shut. He could have hid from the cameras and not said a word to the media. Instead, he decided to do something that at the time many would have been to afraid to do.  Here's a clip from his news conference announcing his diagnosis.

L.A. Lakers lose heart and soul – The day Johnson announced he had contracted HIV, the media had a lot of questions.  Many journalists wondered how the disease would immediately impact his life and what he would ultimately do after retiring from the Los Angeles Lakers.  CNN's Michael Cowman filed a report the day of Magic's big announcement and helps answer those questions.
