In a new ad, Oprah Winfrey lends her star power to Weight Watchers, even though she says she’s never been paid to endorse anything before. She told Weight Watchers she had to try their points system, and when she lost 15 pounds using it, she agreed to do the ad. NBC’s Stephanie Gosk reports for TODAY on Oprah’s impact and how she’s sent Wight Watchers stock soaring.
