In Dr. Phil's wake, Oprah helped another health and medical expert find his footing in the world of television. Mehmet Oz, a cardiothoracic surgeon, first appeared on Oprah's show in 2004. Clad in his blue surgical scrubs, "Dr. Oz" was a Tuesday regular on "The Oprah Winfrey Show" for five seasons, touting both traditional and alternative ways to achieve good health.
