Today marks the end of an era. After 25 years of groundbreaking television work, Oprah Winfrey is saying goodbye to her weekly audience of 44 million viewers. Since its launch in 1986, The Oprah Winfrey Show has transformed daytime television. Initially debuting in last place, the show eventually went on to become one of the highest rated talk shows in American history.

Although her popular show is coming to end, the multimedia mogul doesnâ€™t stop as she continues to build her brand with Harpo Films, Oprah Radio, O Magazine and her last endeavor, the Oprah Winfrey Network (OWN).
