J.J. Jackson, an MTV VJ in the early 1980s, died on Wednesday of a heart attack at the age of 62. Jackson spent five years in the spotlight at MTV helping to popularize a new form of media: music videos. In the late ’80s he went back to working in radio and continued hosting shows in Los Angeles. http://www.billboard.com/bb/daily/article_display.jsp?vnu_content_id=1000467935
