TV viewers are notoriously fickle, but not when it comes to Oprah Winfrey.

The billionaire queen of daytime television has recaptured the No. 1 position as America's favorite TV personality, after losing it three years ago.

Winfrey, considered one of the most successful businesswomen ever, was tapped for the honor in 1998 and 2000.

But by the end of 2001, she had slipped back to third place, behind sitcom fave Drew Carey and Regis Philbin.

Now, she's back on top of the heap, while Carey and Philbin -- once the can-do-no-wrong darlings of ABC -- have vanished from the Top 10 list, compiled by the Harris Poll.

Oprah is followed, in order, by Ray Romano, David Letterman, Katie Couric and Bill O'Reilly.

Romano, star of Everybody Loves Raymond and now No. 2, was in fifth place at the end of 2001-- but he's riding even higher on the still-growing success of his smash sitcom.

Letterman moved up from fourth to third on the list.

Following Today show cutie Couric and Fox News Channel's powerhouse gabber O'Reilly are Jennifer Aniston, Dr. Phil McGraw, Tom Brokaw, Jay Leno and Dan Rather.

Couric moved up five places from No. 9, and O'Reilly moved up two places from No. 7. Aniston, Dr. Phil, Brokaw and Rather were not in the top 10 last year.

In addition to Carey and Philbin, Kelsey Grammer (formerly No. 8) and Rosie O'Donnell (formerly No. 10) also dropped out of the Top 10 this year.

Among different demographic groups, Winfrey is No. 1 with women, people 40 years and over, Hispanics and African-Americans (tied with Bill Cosby).

Oprah also was tops among women in the 2001 poll while Carey was the favorite among African-Americans and Letterman topped the poll of Hispanics that year.

Romano is the most popular TV star among white fans.

Conan O'Brien, who doesn't make the Top 10 overall, is tops with people 18 to 24 years old. In 2001, Carey topped that age group. Aniston is the favorite of people 25 to 29, replacing Letterman.

But Letterman is the most popular star among those 30 to 39, knocking Carey from yet another 2001 top spot.

The Harris Poll surveyed 2,201 adults nationwide online between Jan. 21 and 27.
