No doubt aware of Oprah Winfrey's influence when it comes to book sales, former Alaska governor and vice-presidential candidate Sarah Palin has agreed to give Winfrey a "world exclusive interview" on Nov. 16, a day before the official publication of her memoir Going Rogue An American Life . Palin's decision was all the more stunning given the fact that last year she turned down an invitation by Winfrey, who had supported Barack Obama during the election campaign. Although many critics had predicted that Winfrey's ratings would take a hit because of her political stand, they are actually up 15 percent from the same period last year -- to 7.4 million viewers. By contrast, NBC's Today show averages about 5.1 million viewers, while ABC's Good Morning America averages about 3.7 million.
