Time 100 is a list of the top 100 most influential people in the world, assembled by the American news magazine Time. First published in 1999 as the result of a debate among American academics, politicians, and journalists, the list is now a highly publicized annual event. Appearing on the list is often seen as an honor, and Time makes it clear that entrants are recognized for changing the world, regardless of the consequences of their actions. The final list of influential individuals is exclusively chosen by Time editors, with nominations coming from the Time 100 alumni and the magazine's international writing staff. Only the winner of the Reader's Poll, conducted days before the official list is revealed, is chosen by the general public. The corresponding commemorative gala is held annually in Manhattan.
