Steve Jobs has resigned as chief executive of Apple, handing the reins to chief operating officer Tim Cook.
No specific reason was given for Jobs' resignation, but he went on his second spell of sick leave in January.
In a letter to the board, Jobs said: "I have always said if there ever came a day when I could no longer meet my duties and expectations as Apple’s CEO, I would be the first to let you know. Unfortunately, that day has come."
He will remain at Apple as chairman of the board, the company said. He recommended Cook as his replacement - suggesting that was the "succession plan" all along - advice the board has apparently taken.
Jobs' departure from the helm at Apple will leave many wondering whether the company will continue its incredible success. Cook has capably headed the firm in Jobs' absence, but the charismatic Apple founder is believed by many to be central to its success.
"The board has complete confidence that Tim is the right person to be our next CEO," said Art Levinson, chairman of Genentech and Apple board member. "Tim's 13 years of service to Apple have been marked by outstanding performance, and he has demonstrated remarkable talent and sound judgment in everything he does."
Of course, Jobs leaves his role as chief executive at a time when the company is at a high point, posting record profits, consistent increases in Mac sales despite wider troubles in the industry, and becoming the largest tech firm by market value. As well, Jobs isn't stepping entirely away from the firm, keeping a high-profile role as chairman of the board.
"I believe Apple’s brightest and most innovative days are ahead of it. And I look forward to watching and contributing to its success in a new role," Jobs added. "I have made some of the best friends of my life at Apple, and I thank you all for the many years of being able to work alongside you."
