founder Steve Jobs' $4.6 billion worth of shares in The Walt Disney Co. are now in a trust run by his wife, Laurene Powell Jobs. That's according to a securities filing made Wednesday. Jobs acquired the 138 million shares when Disney bought his Pixar Animation Studios for $7.4 billion in 2006. With a 7.7 percent stake, Jobs' trust is Disney's largest single shareholder. Jobs bought the fledgling computer imaging company from “Star Wars” creator George Lucas for a total investment of $10 million in 1986 and kept it going with his own money. He later took Pixar public after the successful debut of “Toy Story” in 1995. The creative executive behind the iPod, iPhone and iPad died last month at age 56 after battling pancreatic cancer.
