The Chronicle of Philanthropy released its list of America's top 50 philanthropists for 2010 -- including these six big names in tech.
Facebook founder and CEO Mark Zuckerberg made a splash in September with a company blog post titled "Startup: Education" -- plus an appearance on Oprah.
In the post, Zuckerberg waxed poetic about the problems in school systems nationwide -- and especially that of one troubled New Jersey city. "Newark has unfortunately become a symbol of public education's failure -- of a status quo that accepts schools that don't succeed," Zuck wrote.
Zuckerberg said he would donate Facebook stock valued at $100 million to Newark's public schools. As part of the deal, New Jersey Governor Chris Christie handed some control of the state-run school system to Newark Mayor Cory Booker.
Zuckerberg, who dropped out of Harvard in 2002 to get Facebook off the ground, wrote that he looked forward to giving Newark's 40,000 students the same educational opportunities he had received.
