Time: Gaga, O'Brien influential artists

NEW YORK, April 29 (UPI) -- U.S. pop star Lady Gaga, talk-show host Conan O'Brien and filmmaker Kathryn Bigelow have made Time magazine's list of the most influential artists.

Also appearing on the roster are U.S. media mogul Oprah Winfrey, Russian conductor and opera company director Valery Gergiev, and British actor Robert Pattinson, as well as U.S. actor-producer Ashton Kutcher, U.S. television writer Suzanne Collins, U.S. country music star Taylor Swift and U.S. actor Neil Patrick Harris.

"The Time 100 list is not ranked. Time makes no distinction of level of influence among the 100 members on the list. There are many factors that go into the layout of a magazine, including graphics, photos, art, design and more," a representative for the magazine said in a statement.
