Oprah Winfrey's star power is still going strong.
Despite quitting her popular syndicated talk show almost two years ago, the OWN mogul tops Forbes 2013 list of the Most Influential Celebrities in America, a title she also held last year.
Winfrey, 59, took the No. 1 spot largely thanks to some very high-profile interviews, including her two-part sit-down with disgraced cyclist Lance Armstrong—in which he admitted doping to win the Tour de France—which garnered 28 million viewers from around the globe.
Her celebrity brand remains viable as well because her company, Harpo Productions, produces The Dr. Oz Show—hosted by protégé Dr. Mehmet Oz—which has been performing like gangbusters in the ratings.
The magazine ranks celebrities based on E-Poll Market Research surveys, which ask Americans about celebrities' likeability traits and personality attributes.
Oprah was rated 48 percent influential. Coming in second on Forbes list was Lincoln director Steven Spielberg who earned a 47 percent influential rating.
Rounding out the top 10 were Dr. Oz (6), Barbara Walters (7), Bono (8), CNBC financial guru Suze Orman (9) and despite dividing partisans on the left and right by talking to an empty chair at the Republican National Convention last year, Clint Eastwood (10).
