Newsweek is getting plenty of buzz for taking on one of the most powerful targets in all of media: Oprah Winfrey, who is none too pleased. This week's cover story accused Oprah of lending credibility to untested holistic medical treatments, as well as other "unorthodox" medicines. Oprah quickly returned fire, saying that her audience was "smart and discerning enough" to make decisions for themselves regarding what type of treatment to receive. Some of the more "out there" treatments that have appeared on Oprah's show include Suzanne Somers saying she takes 60 supplements a day, and Jenny McCarthy saying that vaccinations can cause autism. The feud makes for good press, but Newsweek better hope Oprah doesn't order her army of acolytes to boycott the magazine.
