A look back at the triumphs and tragedies of 2011.
Saudi-born dissident Osama bin-Laden addresses a news conference in Afghanistan, where he and his organization are based, in a May 26,1998 file photo. News of bin Laden's death on May 2 was the top news story on msnbc.com in 2011.
The killing of Osama bin Laden by Navy SEALs at his hideout in Pakistan was the top news event of 2011, followed by the earthquake and tsunami disaster in Japan, according to a ranking on msnbc.com by page views as of Dec. 20.
Here's a look at those events and the three other stories with the most page views:
1. The May 2 death of bin Laden, the al-Qaida leader who masterminded the Sept. 11, 2001, terrorist attacks. Several stories about his death generated more than six million page views each, but a story that detailed how the U.S. used intelligence about the people in bin Laden's circle, including his personal couriers, was by far the No. 1 single story:

2. Japan's earthquake and tsunami on March 11 left nearly 20,000 people dead or missing. The quake triggered a tsunami that caused massive inland flooding and crippled the Fukushima nuclear reactor, sparking the largest nuclear disaster since the 1986 Chernobyl disaster in Ukraine. Here are the two stories on Japan's tragedy that got the most attention:

3. An article on the murder acquittal on July 5 of Florida mother Casey Anthony, who had been accused of killing her toddler daughter, had the second-most page views on the site. After a trial that lasted six weeks, a jury found Anthony not guilty of first-degree murder, aggravated child abuse and aggravated manslaughter of a child, but guilty of four misdemeanor counts of providing false information to a law enforcement officer. With credit for time served, she was released July 17.
