Oprah Winfrey had the temerity to announce the ending of her talk show in 2011 while this Oprah expert was otherwise engaged. It ain't over tomorrow, but The End Is Near. This is completely consistent with her style of doing things that are economically prudent and psychologically smart (she would say soul-smart); when you get the lesson, it's over. There are new worlds to conquer on cable; a lot of us can sympathize with the need for ongoing learning and new challenge. She sure doesn't need the money. She also has some time to cultivate a structure for succession that is not now in place. Ellen? Dr. Oz? Oprah already helps produce the latter's show. As the O-empire has grown, she has taken her hands off lots of things. The culture pundits say her influence will wane; I think it's morphing, going where the action is, with niche audiences and concerns.
