The industry has been betting that the daytime diva would extend The Oprah Winfrey Show for at least another year or two because of the huge cash license fees which stations have long paid her. But people around Oprah are telling me that won't happen. They say that Discovery Communications chief David Zaslav has demanded that Oprah "move it or lose it" -- move her talk show to OWN, or risk losing the Oprah Winfrey Network altogether. I've learned that in coming days Winfrey and Discovery will issue a press release announcing OWN's on-air launch for the start of 2011. And, in several weeks, Oprah will tell the public that she's ending her syndicated Chicago-based daytime talk show when her current deal runs out and moving it to OWN headquarters in Los Angeles probably as soon as mid-2011.
