Steve Jobs, who co-founded Apple in 1976 and returned in 1997 to lead one of the most consequential corporate turnarounds in business history, died at the age of 56.
Under his second tenure Apple introduced the iMac, iPod, iTunes Store, iPhone and iPad, and became for a time the most valuable listed company in the world. His approach to industrial design and integrated hardware and software reshaped consumer electronics, music distribution and mobile computing.
Tributes were left outside Apple stores worldwide. He had stepped down as chief executive six weeks earlier, handing the role to Tim Cook.
