Steve Jobs resigns as Apple CEO; Tim Cook takes helm

24.08.2011

This year's leave of absence was Jobs' second. In 2004 he underwent surgery to treat a rare form of pancreatic cancer and returned to work soon after. But in early 2009 Jobs took six months off to treat what he called a "hormone imbalance" that made him appear gaunt. During that leave he underwent a liver transplant.

Under his leadership, Apple developed the iPod, iPhone and iPad -- devices that have each defined their technology categories.
