Apple Computer started in a garage
In 1976, when Jobs was just 21, he and Steve Wozniak started Apple Computer in the Jobs’ family garage. They funded their entrepreneurial venture by Jobs selling his Volkswagen bus and Wozniak selling his beloved scientific calculator. Jobs and Wozniak are credited with revolutionizing the computer industry with Apple by democratizing the technology and making machines smaller, cheaper, intuitive and accessible to everyday consumers.
Wozniak conceived of a series of user-friendly personal computers, and — with Jobs in charge of marketing — Apple initially marketed the computers for $666.66 each. The Apple I earned the corporation around $774,000. Three years after the release of Apple's second model, the Apple II, the company's sales increased by 700 percent to $139 million.
In 1980, Apple Computer became a publicly traded company, with a market value of $1.2 billion by the end of its very first day of trading. Jobs looked to marketing expert John Sculley of Pepsi-Cola to take over the role of CEO for Apple.
The next several products from Apple suffered significant design flaws, however, resulting in recalls and consumer disappointment. IBM suddenly surpassed Apple in sales, and Apple had to compete with an IBM/PC-dominated business world.
In 1984, Apple released the Macintosh, marketing the computer as a piece of a counterculture lifestyle: romantic, youthful, creative. But despite positive sales and performance superior to IBM's PCs, the Macintosh was still not IBM-compatible. Sculley believed Jobs was hurting Apple, and the company's executives began to phase him out. Not actually having had an official title with the company he co-founded, Jobs was pushed into a more marginalized position and thus left Apple in 1985.
Pixar the next venture after being thrown out of Apple Inc
In 1986, Jobs purchased an animation company from George Lucas, which later became Pixar Animation Studios. Believing in Pixar's potential, Jobs initially invested $50 million of his own money in the company. The studio went on to produce wildly popular movies such as Toy Story, Finding Nemo and The Incredibles; Pixar's films have collectively netted $4 billion. The studio merged with Walt Disney in 2006, making Steve Jobs Disney's largest shareholder.
Reinventing Apple – Back to Apple
After leaving Apple in 1985, Jobs began a new hardware and software enterprise called NeXT, Inc. The company floundered in its attempts to sell its specialized operating system to mainstream America, and Apple eventually bought the company in 1996 for $429 million. In 1997, Jobs returned to his post as Apple's CEO. Just as Jobs instigated Apple's success in the 1970s, he is credited with revitalizing the company in the 1990s.
With a new management team, altered stock options and a self-imposed annual salary of $1 a year, Jobs put Apple back on track. Jobs’ ingenious products (like the iMac), effective branding campaigns and stylish designs caught the attention of consumers once again. In the ensuing years, Apple introduced such revolutionary products as the Macbook Air, iPod and iPhone, all of which dictated the evolution of technology. Almost immediately after Apple released a new product, competitors scrambled to produce comparable technologies.
Battle with Cancer
In 2003, Jobs discovered that he had a neuroendocrine tumor, a rare but operable form of pancreatic cancer. Instead of immediately opting for surgery, Jobs chose to alter his pesco-vegetarian diet while weighing Eastern treatment options. For nine months, Jobs postponed surgery, making Apple's board of directors nervous. Executives feared that shareholders would pull their stock if word got out that their CEO was ill. But in the end, Jobs' confidentiality took precedence over shareholder disclosure. In 2004, he had a successful surgery to remove the pancreatic tumor. True to form, in subsequent years Jobs disclosed little about his health.
Early in 2009, reports circulated about Jobs' weight loss, some predicting his health issues had returned, which included a liver transplant. Jobs responded to these concerns by stating he was dealing with a hormone imbalance. Days later, he went on a six-month leave of absence. In an e-mail message to employees, Jobs said his "health-related issues are more complex" than he thought, then named Tim Cook, Apple’s chief operating officer, as “responsible for Apple's day-today operations."
After nearly a year out of the spotlight, Steve Jobs delivered a keynote address at an invite-only Apple event on September 9, 2009. He continued to serve as master of ceremonies, which included the unveiling of the iPad, throughout much of 2010. However in January 2011, Jobs announced he was going on medical leave. In August, he resigned as CEO of Apple, handing the reigns to Cook, and in October he passed away.
