In this week’s issue, TIME reveals its list of the 100 most influential people in the world. As TIME managing editor Richard Stengel writes in his Letter to Readers, “The TIME 100 is not a list of the smartest, the most powerful, or the most talented—it is a thoughtful and sprightly survey of the most influential individuals in the world. Influence, like those other categories, is subjective, but you try to measure it in the effect people have on the world.” The list is divided into five subsections: Leaders and Revolutionaries; Builders and Titans; Artists and Entertainers; Scientists and Thinkers; and Heroes and Pioneers.
The TIME 100 features often-surprising pairings of the influentials and the guest contributors TIME selects to write about them. This year’s list includes Bill Clinton on Tony Blair, George Clooney on Brad Pitt and Angelina Jolie, Silvio Berlusconi on George W. Bush, Paul Steiger on Rupert Murdoch, Michelle Obama on Oprah Winfrey, and Donny Osmond on Miley Cyrus.
