He was a truly global force.

Steve told me as proud as he was of Apple and Pixar, his real pride was his family.  He was a thoughtful and tender father, and loved nothing more than hanging out in the house with his belle Laurene and the kids.

[Updated at 12:55 p.m.] As the world continues to pay tribute to Steve Jobs, the master showman and cult hero, it appears the appetite for more knowledge about the man is growing even more. For millennials, the interest may be high too, with some living in a world where Apple has always been a presence.

Apple fans won't have to wait as long to read the authorized story of Steve Jobs' life. Responding to a rush of interest following Wednesday's death of the Apple co-founder, Simon & Schuster announced it's moving up the publication date of its Steve Jobs biography from November 21 to October 24.

The book by Walter Isaacson, titled simply, "Steve Jobs," rocketed from 437 to No. 1 on Amazon's bestseller list - a spike of 43,000% - in the hours after Jobs' death, thanks to pre-orders.

[Updated at 12:34 p.m.] One of the other big reactions on the web to Steve Jobs' death has been remembering some of the iconic images that were a part of Apple's products. Like the "spinning wheel tribute" we mentioned below, the famous "sad mac" icon is now taking on a new meaning.

The words and icon have been included in thousands of tweets and even made it on the front page of the Bismark Tribune.

[Updated at 12:09 p.m.] One of the most popular or viral tributes to Jobs' death comes courtesy of a design from Jonathan Mak, a student at Hong Kong’s Polytechnic University School of Design. He posted the design on Tumblr and it immediately went viral.

[Updated at 11:30 a.m.] Nancy F. Koehn,  a historian at Harvard Business School who holds the James E. Robison chair of Business Administration, writes in a column for CNN.com that Jobs' central insight was that we live in transformative times.

"Steve Jobs died Wednesday at the age of 56. Within minutes of the announcement, Twitter and other digital channels were flooded with outpourings of grief for a very private man who leaves a very big mark on the world," she wrote. "It is the footprint, not of a manager or philanthropist, but of an entrepreneur. His legacy is that of an individual who used his drive, vision, curiosity and keen intelligence to follow new possibilities relentlessly without being deterred by the obstacles on his path."

[Updated at 11:09 a.m.] Omekongo Dibinga, an iReporter from Washington, weighs in on the loss of Steve Jobs:

“Despite the great products has brought to the world, Steve Jobs' work as a motivator is his greatest creation. He is a classic example of what happens when we drown the naysayers and follow our passion. It is a lesson that will not pass me by. Rest in peace.”

[Updated at 10:42 a.m.] The website XKCD, a daily webcomic that often focuses on technology, science and pop culture, paid tribute to Jobs with an animated gif called "Eternal Flame."

For those who know the "spinning wheel" so well, the tribute is simple but beautiful. When you mouse over the image on their website the text says: "there's always hope that if you sit and watch for long enough, the beachball will vanish and the thing in interrupted will return."

[Updated at 10:14 a.m.]  We knew Steve Jobs best as the face of Apple - the man who introduced the company's biggest products in front of cheering audiences filled with fans and journalists. He was in his element onstage in a black turtleneck and jeans, playing with the new iPod, iPhone or iPad. But Jobs also had a life offstage, one filled with celebrities, foreign leaders and, perhaps most importantly, his fans. See a gallery of Jobs' life offstage

"Self-explanatory. RT this. Not for me, but El Jefe himself," the tweet said.

[Updated at 9:46 a.m.] Apple co-founder Steve Wozniak, who started the company with Steve Jobs in 1976, spoke with Carol Costello, Christine Romans and Ali Velshi on CNN's "American Morning" about what it was like working with Jobs, and how he hopes the world will remember him.

[Updated at 9:24 a.m.] Former Facebook president Sean Parker posted a long note on his Facebook page in which he called Steve Jobs an "innovator, iconoclast and American hero."

"Today is an incredibly sad day for me, and indeed for anyone who considers themselves a technologist or entrepreneur. It is also a sad day for anyone who believes in the value of creativity and the importance of innovation, and for the millions of people who were touched by the creative genius evidenced in the many products and companies created by Steve Jobs throughout his remarkable career. Steve Jobs was the most important technology leader of our era—perhaps even the most important business leader of our era. He was also a unique figure in the world of business and technology, a man who demonstrated—more so than any other—that pure force of will, energy, and creative drive can change the world for the better," the note said.

At an iVigil in Hong Kong:

Fans pay tribute to Steve Jobs online and at Apple stores

[Updated at 8:48 a.m.] iReporter Billie Criswell of Frankford, Delaware sent in his tribute to jobs headlined "iMourn: The Passing Of Steve Jobs."

"I was really sad to hear he passed, it's kind of a great loss in our technological society, there's certainly people who blaze the trail, and Steve Jobs is one of those guys," Criswell said. "I love the products, I'm such a huge fan of Apple products. It's technology that just lasts forever. My uncle has an 11 year old Apple laptop and it still runs, and you don't get that out of other brands."

[Updated at 8:48 a.m.] iReporter Ryan Navarro and his colleagues at the design group RipeConcepts in the Philippines were '"saddened by the news of a great innovator who has been very instrumental in putting together what could be the greatest invention of our generation."

Navarro has been a loyal Apple customer for thirteen years and Apple products can be seen in use throughout the company.

If he could have said one thing to Steve Jobs, it would have been: "Thank you and continue to stay hungry and foolish."

It seems many other Apple fans out there feel the same, echoing the sentiments Jobs said when he spoke at Stanford University in 2005. This morning #STAY HUNGRY is a top trend on Twitter.

Five other memorable quotes from Steve Jobs

[Updated at 8:41 a.m.] Cory Booker, the mayor of Newark, New Jersey, paid tribute to Jobs in a tweet with one of his most known quotes and perhaps the one most telling about the man himself:

[Updated at 8:35 a.m.] Simon Garfield, the author of "JUST MY TYPE: A Book About Fonts," published by Gotham Books, a member of Penguin Group USA, wrote an opinion column for CNN about "One thing we owe to Steve Jobs." And it might not be what you think. Here's a bit of his column below. You can continue reading his column here

"The news about the passing of Steve Jobs comes one day after a new iPhone was announced, a launch that took place without a man with a black polo neck presiding. And still, somehow, Steve Jobs dominated the proceedings. These last few months, as his illness kept him away from the office, it's been clear that we owe him for more than just upping the pixels on the phone camera and an ever-faster processor.

Even non-Mac believers - even anti-Mac folk - will acknowledge begrudgingly that he's been an invincible tech inspiration over the years. Simple really: much of the time he led and others followed. But there is something more fundamental to thank Jobs for - the very screen text you're reading now, the very fact that we can express ourselves digitally with emotion, clarity and variety.

Steve Jobs was the first to give us a real choice of fonts, and made Type Gods of us all."

The spiritual side of Steve Jobs

[Updated at 9:35 p.m. ET] Statement from President Obama: "Michelle and I are saddened to learn of the passing of Steve Jobs. 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.

By building one of the planet’s most successful companies from his garage, he exemplified the spirit of American ingenuity.

By making computers personal and putting the Internet in our pockets, he made the information revolution not only accessible, but intuitive and fun.  And by turning his talents to storytelling, he has brought joy to millions of children and grownups alike. Steve was fond of saying that he lived every day like it was his last.  Because he did, he transformed our lives, redefined entire industries, and achieved one of the rarest feats in human history: he changed the way each of us sees the world.

The world has lost a visionary. And there may be no greater tribute to Steve’s success than the fact that much of the world learned of his passing on a device he invented. Michelle and I send our thoughts and prayers to Steve’s wife Laurene, his family, and all those who loved him."
