Steve Jobs, jutawan dan juga pengasas kepada Apple dan 'mastermind' kepada revolusi dunia siber, telefon dan juga industri musik, telah meninggal dunia di California pada usia 56 tahun.
Jobs stepped down in August as chief executive of the company he helped set up in 1976, citing illness. He had been battling an unusual form of pancreatic cancer, and had received a liver transplant in 2009.
Jobs wrote in his letter of resignation: "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."
Apple released a statement paying tribute to Jobs: "Steve's brilliance, passion and energy were the source of countless innovations that enrich and improve all of our lives … The world is immeasurably better because of Steve."
Bill Gates, the former chief executive of Microsoft, said in a statement that he was "truly saddened to learn of Steve Jobs's death".
He added: "The world rarely sees someone who has had the profound impact Steve has had, the effects of which will be felt for many generations to come.
"For those of us lucky enough to get to work with him, it's been an insanely great honour. I will miss Steve immensely."
He is survived by his wife, Laurene, and four children. In a statement his family said Jobs "died peacefully today surrounded by his family … We know many of you will mourn with us, and we ask that you respect our privacy during our time of grief".
Jobs was one of the pioneers of Silicon Valley and helped establish the region's claim as the global centre of technology. He founded Apple with his childhood friend Steve Wozniak, and the two marketed what was considered the world's first personal computer, the Apple II.
He was ousted in a bitter boardroom battle in 1985, a move that he later claimed was the best thing that could have happened to him. Jobs went on to buy Pixar, the animation company behind Finding Nemo, Cars and Toy Story and maker of some of the biggest blockbusters in cinema history.
He returned to Apple 11 years later when the company was being written off by rivals. What followed was one of the most remarkable comebacks in business history. Apple was briefly the most valuable company in the world earlier this year, knocking oil giant Exxon Mobil off the top spot. The company produces $65.2 billion a year in revenue compared with $7.1 billion in its business year ending September 1997.
Starting with his brightly coloured iMacs, Jobs went on to launch hit after hit. In the process he transformed personal computing. Then came the success of the iPod, which revoltionised the music industry, leading to a collapse in CD sales and making Jobs one of the most powerful voices in an industry he loved. His firm was named in homage to the Beatles' record label, Apple. But it wasn't a complement that the Fab Four appreciated. The two were engaged in a lengthy legal battle which finally ended last year when the Beatles allowed iTunes to start selling their back catalogue.
Jobs initially hid his illness but his startling weight loss started to unnerve his investors. He took a six month medical leave of absence in 2009, during which he received a liver transplant, and another medical leave of absence in mid-January before stepping down as chief executive in August.
