Oct. 15, 2012— -- intro: Oprah Winfrey is one of the most influential figures in media.

She placed second on Forbes' "World's Most Powerful Celebrities" list this year, and has estimated earnings of $165 million.

Aside from her wildly popular syndicated talk show, "The Oprah Winfrey Show," which ended last year, the mogul also has a 24-hour cable network, OWN, a popular book club and an award-winning magazine.

The so-called Oprah Effect has proved to be incredibly powerful several times over. Endorsements, frequent show appearances or, better yet, a regular segment on the media titan's show can be the golden ticket to a successful career.

Many household TV names got their start on the "Oprah Winfrey Show" and went on to become icons themselves and make fortunes. Here are eight stars who shot to fame thanks to Winfrey and remain close to the "Oprah" brand.

They didn't speak to each other for 11 years, but a public reconciliation in February 2011 on "The Oprah Winfrey Show" proved to be a master class in how to heal a friendship.

Now, forgiveness and redemption are themes on Vanzant's new show, "Iyanla: Fix My Life," which premieres on Winfrey's OWN network tonight.
