Time unveils Person of the Year: The Protester

Time Magazine's choice for the person who made the single greatest impact in 2011 is The Protester.

The pick reflects the importance of demonstrations during 2011 - from the Arab Spring to Occupy Wall Street and the recent Russian rallies.

The weekly news magazine said the award recognised protesters for "redefining people power" around the world.
