Tech companies bring jobs, innovation and billions of dollars to the Peninsula.
So it's not surprising that some of the wealthiest Americans made their fortunes in the Silicon Valley and San Francisco, and still reside in the region.
Forbes magazine released its annual list of the richest people on the planet this month. The rankings include a who's-who of tech CEOs who call the Peninsula home.
Woodside's Larry Ellison leads the rankings for the region and all of California.
Ellison ranks No. 5 on Forbes' Billionaires list, the same place he held in 2011. He is the third richest person in the United States, the magazine reports. The 68-year-old Woodside resident, made his fortune as co-founder and CEO of Oracle Corporation, is worth an estimated $43 billion.
In Los Altos Hills, Sergey Brin, co-founder of Google, and Jerry Yang, co-founder of Yahoo!, rank 21st and 328th in the world, respectively.
