Tributes have been pouring in from across the technology world to mark the passing of Steve Jobs, the former CEO of Apple.
Jobs died last night after losing a long hard fought battle with cancer and as the news spread around the world many well known tech figures have wanted to pay tribute to the man and his impact.
The most popular word to describe Jobs was "visionary" with Mike Lazaridlis and Jim Balsillie, co-CEO's of Research in Motion describing him in such terms.
Even competitors spoke with great respect about Jobs and the impact he made on the industry.
"He was a great man with incredible achievements and amazing brilliance. He always seemed to be able to say in very few words what you actually should have been thinking before you thought it. His focus on the user experience above all else has always been an inspiration to me," said Larry Page, CEO of Google.
Lord Sugar tweeted that he had entered the industry at the same time as Jobs and his rival was a great visionary.
"Gutted Steve Jobs died. We started our computer biz at the same time and were competitors through the 80s. great visionary. Sadly missed. RIP," he tweeted.
Long time Apple fan Stephen Fry also took to Twitter to say that Jobs had "changed the world".
Paul Allan, co-founder of Microsoft, said that the way that Jobs had fought so hard against cancer was an inspiration to others battling health issues.
Barack Obama, US President, said that the world had lost a visionary and other household names in the tech world have also paid tribute.
Michael Dell, founder and CEO of Dell also described Jobs as visionary and added that "the technology industry lost an iconic legend and I lost a friend and fellow founder."
Bill Gates, former boss at Microsoft, also expressed a sense of personal loss: "For those of us lucky enough to get to work with Steve, it's been an insanely great honor. I will miss Steve immensely."
Richard Holway, chairman of analyst firm TechMarketView, said that Apple products had been something he had used for years and had improved the life of himself and his family.
"I've likened Jobs to my other hero - Isambard Kingdom Brunel. Both achieved greatness across many different things - bridges, railways, tunnels, buildings, ships in the case of Brunel. Both were passionate workaholics. Both were sticklers for detail. Both died young. Both had, or in the case of Jobs will have, huge effects on our lives for many years, decades, centuries after their death," he said.
