On Wednesday night, Apple's website simply showed a picture of the company's founder and the 56 years he lived.
In a statement, President Obama said, "the world has lost a visionary. 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."
DJ Miller is one of those who learned the news on his iPad.
"He had such a hand in how we interact with machines and how they interact with us," Miller told ABC7.
Jobs changed the way people use computers. He revolutionized the music industry with iPods and iTunes. And his iPhone revolutionized the cell phone industry, creating the market for smart phones.
"People are going to associated him with innovation. Maybe it wasn't him who actually thought up this stuff. But he was the face behind the company that actually produced the stuff that changed the way people do things," said Josh Dunlop, Apple customer.
Apple CEO Tim Cook sent an email to employees Wednesday saying, in part, "those of us who have been fortunate enough to know and work with Steve have lost a dear friend and an inspiring mentor. Steve leaves behind a company that only he could have built, and his spirit will forever be the foundation of Apple."
In the meantime, longtime Apple fans are contemplating Jobs' legacy.
"He integrated technology with regular, everyday life," said Nick Johnson, Apple customer
The tributes have been pouring in from around the world. But perhaps one of the most poignant comes from Microsoft founder Bill Gates who knew Jobs for 30 years as a competitor, colleague and friend. Gates said, "the world rarely sees someone who has the profound impact Steve had, the effects of which will be felt for many generations to come."
