Our NewsDepth A+ this week goes to someone you've already heard of - the man who created Facebook, Mark Zuckerberg.
His wealth is estimated to be worth about $45 billion. And last week, the computer programmer and philanthropist and his wife Priscilla announced that they're going to give away almost all of it.
A company they created called the Chan Zuckerberg initiative will use the money to do what they called “advance human potential", fighting to end disease, to boost education, and to connect more people to the information available on the internet.
They did not say how fast money would become available or exactly how it will be spent.
