Giving it away: A look at past decade's $1 billion donations
SAN FRANCISCO (AP) -- Mark Zuckerberg's pledge to give away Facebook stock worth $45 billion puts him at the forefront of a philanthropic class that has promised to donate most of their fortunes.
The elite list includes three men -- Microsoft co-founder Bill Gates, stock market sage Warren Buffett and Oracle co-founder Larry Ellison -- who are wealthier than Zuckerberg, according to Forbes magazine's latest rankings.
That trio and Zuckerberg are among the 138 wealthy individuals and families who have signed a "giving pledge" committing them to give away most of their fortunes in an attempt to fix society's problems.
Zuckerberg, 31, and his wife Priscilla Chan, 30, waited until the birth of their first child, a girl named Max, to reveal their intention to give away all but 1 percent of the Facebook stock that accounts for most of their fortune.
Here's a look at the donations of at least $1 billion announced during the past decade, as tracked by the Chronicle of Philanthropy:
