Oprah Winfrey

Continuing her way toward total world domination, talk-show queen Oprah Winfrey has been named "Person of the Year" by People for the Ethical Treatment of Animals.

Winfrey was selected for using her talk show to bring light to issues important to the Norfolk, Va.-based animal rights group's mission, with episodes that have, for example, focused on puppy mills and the treatment of chickens and other animals in factory farms. Winfrey also went on a vegan diet for a week, and in April, dedicated an episode of her show to her late cocker spaniel Sophie, who died at age 13.

Winfrey has "used her powerful voice to defend those without one," PETA president Ingrid Newkirk said in a statemement. Winfrey, who was unavailable for comment, according to The Associated Press, will receive a plaque and a letter of appreciation.

Previous winners of the PETA award include U.S. Sen. Robert Byrd of West Virginia in 2007 and the founders of the San Francisco-based cleaning product company Method in 2006.
