Larry Ellison: Oracle co-founder who overtook Musk as world's richest person

Larry Ellison, the co-founder of software company Oracle, is having a good year. His friend Donald Trump is in the White House, his son David Ellison has taken over the storied media company CBS, and on Wednesday he surpassed his buddy Elon Musk to win the title of the "world's richest man". Oracle's stock went wild with the news, pushing his fortune even higher. Ellison's net worth shot up to $393bn, surpassing Musk's $384bn - although, by the time markets closed on Wednesday, Musk was back ahead. Ellison is not as much of a household name as Musk, but he's largely influential in Silicon Valley and more recently, politics.
