Video: Biggest Moments of 2011

2011 was a year of extremes.  From the tragedy of Japan’s devastating earthquake and tsunami, to the pageantry of a British Royal wedding; from the wave of revolutionary change in Egypt, Tunisia and Libya, to the solemn commemoration that took place on September 11, we reflect on a passing year filled with emotion, knowing the world will never be the same.
