Oprah Winfrey, the media mogul-juggernaut, is going to end her successful daytime talk show when her 25th season ends on September 9, 2011. She will be making the announcement on her program today. As for her future, the NY Times says she's expected to "concentrate on the forthcoming cable channel that will bear her name... The move represents an enormous bet — that her popularity and golden touch with programming can sustain an entire cable channel and that she’ll remain a central cultural figure even without the mass exposure of broadcast television every day."
