CUPERTINO, Calif. (AP) - Apple founder Steve Jobs has died. The former CEO invented and masterfully marketed gadgets including PC's, the iPod and iPhone.
Apple announced his death without giving a specific cause. Jobs, who was 56, had battled cancer in 2004 and underwent a liver transplant in 2009 after taking a leave of absence for unspecified health problems. He took another leave of absence in January - his third since his health problems began - and officially resigned in August.
Jobs started Apple with a high school friend in a Silicon Valley garage in 1976. He was forced out a decade later and returned in 1997 to rescue the company. During his second stint, it grew into the most valuable technology company in the world.
