Programming note: I will be talking about the Oprah Effect today, a few minutes after 17:00, live on the eNews Channel.

I will be appearing on the eNews Channel (DStv 403) as a TV critic later this afternoon - a few minutes after 17:00 - to talk and discuss the Oprah Winfrey Effect.

With the end of The Oprah Winfrey Show in America where the final episode was just broadcast after 25 years, I'll weight in, in a live discussion, with a bit of my own analysis, opinion and perspective on the long-running TV show and the famous talk show host.
