Television talk show queen Oprah Winfrey was named the most powerful celebrity in the world on Wednesday as forbes.com released its annual list of the top movers and shakers in the entertainment industry.

Winfrey, 59, who was ranked in the top spot despite her signature daytime television show Oprah ending its 25-year run in 2011, headed a 100-strong list which featured six women in the top 10.

Forbes.com uses a complex methodology to come up with its list, taking into account various factors including earnings, the number of mentions each celebrity gets in print and television and their Internet presence before deciding the rankings.

The website also gives each celebrity a marketability score out of 100 developed by a California-based market research firm.

Winfrey made an estimated $77 million between June 2012 and June 2013, significantly less than other rivals on the list but came out on top after scoring well in areas such as press mentions and social networking power, forbes.com said.

In second place was eccentric pop star Lady Gaga, who earned $80 million in the same period.

Hollywood titan Steven Spielberg was third. The legendary director and producer earned a cool $100 million in the past year.

The next three spots were occupied by women from the music world, with Beyonce Knowles in fourth ($53 million), Madonna in fifth ($125 million) and Taylor Swift ($55 million).
