OPRAH Winfrey, now in her 15th year, has scored her worst ratings ever.

In the most recent ratings – for the final week of the December – she dropped below the psychologically significant 5-rating barrier for the first time in her career.

It was a 25 percent drop from a year ago – and around 60 percent of the 8 or 9 million homes that used to watch Oprah religiously a decade ago.

Still, no one is writing the TV star’s obituary quite yet. She remains the No. 1 afternoon talk on TV and the highest-paid woman in show business.
