From Forbes magazine... Bill Gates remains the richest person in the world with a net worth of $75 billion, despite being $4.2 billion poorer than a year ago. He has been No. 1 one for 3 years in a row and topped the list 17 out of 22 years. (In the 30 years FORBES has tracked global wealth, only 5 people have held the title of richest person on planet; 3 of those 5 still rank among the 4 richest in the world including Warren Buffett and Carlos Slim.)
Also holding steady is Buffett at No. 3. Zara ’s Amancio Ortega moves up to No. 2 for the first time, displacing Mexico’s Carlos Slim, who slips to No. 4. Slim’s fortune fell $27.1 billion to $50 billion in the past year, as shares of his telecom business América Móvil tumbled. Facebook’s Mark Zuckerberg had the best year of all billionaires. 
The 31-year-old added $11.2 billion to his fortune and moved up to No. 6 from 16. He and Amazon’s Jeff Bezos both make their first appearance in the top ten of FORBES’ annual ranking of the world’s wealthiest. Another first: A billionaire from China’s mainland, Wang Jianlin, whose company owns AMC Theaters and soon will own Legendary Pictures, has climbed into the top 20.
