Ever since this story came out I was doubtful this ever happened. Oprah is going down in flames. She has been sidelined to some cable network and has lost 90% of her audience. She is so disconnected that she sthinks starting a race war will put her back on top. This was nothing more than a cheap publicity stunt to make herself relevant. She is washed up and will never come back. Wouldn’t be surprised that she is going bankrupt. This is a last ditch attempt like when JC Penny went gay in a delusional effort to boost sales. They shortly went bankrupt. Oprah is doing the same thing here except that she is a race pimp.
You underestimate her actual accomplishments. She left network television voluntarily after doing a daily show for - what - 25 or 30 years that was hugely successful, highly influential and very, very lucrative. She became among the wealthiest persons in the country and enjoyed top ratings until the last year or two of her daily show, after she made the bad mistake of showing her political ignorance by believing Obama would continue to support the capitalist system that had made her so successful.
During her network days, she also gained from spinning off shows for her protegés, Dr. Phil and Dr. Oz. She probably still owns part of those very profitable shows.
She was not forced or "sidelined" to cable -- it was an idea she wanted to try out, so she bought the Discovery Health channel and changed it to OWN. It does seem to be a struggling channel, because she is older now and it hasn't come as easily as her former career, and also because she alienated and continues to alienate her white audience. But she remains an incredibly wealthy person, with widespread business interests here and abroad, and little short of an outright confiscation is likely to change that in her remaining lifetime. Since she is a Democrat, she has a great deal of insulation from that happening.
