In 1976, a California college dropout started a small business in a spare room at his home.
By his death on October 5, 2011 that company, Apple, was worth around $75.18bn and its founder, Steve Jobs, could claim to have touched the lives of nearly everyone on the planet, including celebrities and leaders such as Barack Obama who were quick to pay tribute to him.
"Steve was among the greatest of American innovators – brave enough to think differently, bold enough to believe he could change the world, and talented enough to do it," said the US leader.
The tech wizard passed away after a long battle with pancreatic cancer.

The rise-to-riches story behind Steve and Apple, is one that no one could ever have imagined.
From those modest beginnings, the company grew quickly and Steve headhunted his CEO, John Sculley, from Pepsi with a quote that summed up his legacy: "Do you want to sell sugar water for the rest of your life, or do you want to come with me and change the world?"
And change the world he did. Apple went on to become one of the most successful, innovative and recognisable brands in the world.
It represented, youth, creativity and cutting-edge design.
Steve, meanwhile, became one of the richest and most respected pioneers on the globe, with a net worth estimated by Forbes in 2010 to be in the region of $3.8 billion.

The key to Steve’s success was his talent for bringing technology, business and art together. His genius made computers what they are today – pretty, cool, fashionable and fun.
At technology conferences, his keynote addresses, the so-called 'Stevenote', would have journalists gripped as he unveiled Apple's latest inventions.
His know-how was the inspiration for the current generation of Silicone Valley leaders, like Facebook founder, Mark Zuckerberg, who has described him as “a mentor and a friend”.
"Thanks for showing that what you build can change the world. I will miss you," he said in a statement.
Yet, he was just as skilled at inspiring people outside his industry, and the news of his death has moved everyone from Ashton Kutcher to Kylie Minogue.
The pop star tweeted this tribute to her followers, known as 'lovers' : “From my Mac to all Lovers.....RIP Steve Jobs”.
Meanwhile, Ashton quoted the Apple founder himself on his Twitter page, saying: "Design is not just what it looks and feels like. Design is how it works."
Away from his professional persona, Steve Jobs the man was quietly, but undoubtedly, just as fascinating.
He was given up for adoption as a baby, later studied Buddhism, and confessed to having a daughter out of wedlock. She was born when he was 23, but it took him almost ten years before he acknowledged paternity.
Tributes have been left at Apple stores and offices
Steve met his wife Laurene Powell when she sat in the front row of one of his passionate speeches.
Starting his car to drive away, the tech mogul recalled later, he asked himself did he want to be in a meeting or having dinner with the smart blonde.
He ran back to ask her on a date that led to a 20-year marriage and three more children.
Despite his colourful private life, his legacy is and will always be Apple, that little company which started out in a garage and changed the way we live – just as he knew it would.
