The TIME 100 issue represents our choices for the 100 most influential people in the world. It’s our 10th year doing it, and the cover always presents a special challenge. In some years we put all 100 of them on the cover, with a postage-stamp-size picture of each. This year we are trying something new: seven cover portraits of TIME 100 honorees who reflect the breadth and depth of our list, each one profiled inside—as is our tradition—by an equally luminary voice.
