Oprah's Network Already Getting a Reboot After just two months, advertisers are worried By Evann Gastaldo, Newser Staff Posted Mar 8, 2011 7:30 AM CST 15 comments Comments Presenter Oprah Winfrey speaks onstage during the 83rd Annual Academy Awards held at the Kodak Theatre on February 27, 2011 in Hollywood, California. (Getty Images) (Newser) – Oprah Winfrey’s cable network has been on the air for just two months, and it’s already getting a reboot. Advertisers are worried about struggling ratings—last week, the audience actually fell below the numbers that Discovery Health had been getting before the Oprah Winfrey Network replaced it. (And the horrible reviews probably aren’t helping.) OWN has just one true hit, Season 25: Oprah Behind the Scenes, which is also, not surprisingly, the only show on the network Winfrey actually appears on. That show will be moved from Fridays to Sundays, in an effort to increase its ratings and thus raise the network’s weekly ratings average, the New York Post reports. Network officials are also reassuring advertisers that the entire lineup will be reshuffled over the next few weeks, and that they’ll spend about $5 million in advertising—half of what they spent when the network was launched. The new ad campaign will heavily promote the upcoming celebrity reality shows starring the Judds, Shania Twain, and the Duchess of York. Click for more on OWN, including what the critics think.
