What exactly are you looking for? You can start by going to Oprah's website, Madonna has made compelling comments about her personal struggles. Ellen Degeneres Show, Rosie O'Donnell Show, Arsenio Hall Show, ABC Nightline 1990's-2012, The Today Show to name a few. Also Saturday Night Live. Many feminists from both British and US academia have written essays and thesis about what Madonna has meant to women and sexuality in the Western world. Hope that helps
