Steve Jobs

Steven Paul Jobs (February 24, 1955 – October 5, 2011) was an American entrepreneur, business magnate, inventor, and industrial designer. He was the chair, chief executive officer (CEO), and co-founder of Apple Inc.; CEO and majority shareholder of Pixar; a member of The Walt Disney Company’s board of directors following its acquisition of Pixar; and the founder, chair, and CEO of NeXT. Jobs and Apple co-founder Steve Wozniak are widely recognized as pioneers of the microcomputer revolution of the 1970s and 1980s.

He was born in San Francisco to parents who had to put him up for adoption at birth; he grew up in San Francisco Bay Area during the 1960s. Jobs then attended Reed College in 1972 before dropping out. He traveled through India in 1974 seeking enlightenment and studying Zen Buddhism. Jobs’s declassified FBI report stated that an acquaintance knew that Jobs had used marijuana and LSD while he was in college. Jobs once told a reporter that taking LSD was “one of the two or three most important things” he did in his life.

Jobs and Wozniak co-founded Apple in 1976 to sell Wozniak’s Apple I personal computer. The visionaries gained fame and wealth a year later for the Apple II. In 1979, after a tour of PARC, Jobs saw the commercial potential of the Xerox Alto, which was mouse-driven and had a graphical user interface. This led to development of the unsuccessful Apple Lisa in 1983, followed by the break-through Macintosh in 1984. In addition to being the first mass-produced computer with a GUI, the Macintosh introduced the sudden rise of the desktop publishing industry in 1985 with the Apple LaserWriter addition, the first laser printer to feature vector graphics. Following a long power struggle, Jobs got forced out of Apple in 1985.

 Steve Jobs & Hartmut Esslinger

In 1982 Apple Computer entered into an exclusive $2,000,000 per year contract with Hartmut Esslinger to create a design strategy which transformed Apple from a “Silicon Valley Start-Up” into a global brand. Setting up shop in California for the first time, Esslinger and Frogdesign created the “Snow White design language” which was applied to all Apple product lines from 1984 to 1990, commencing with the Apple IIc and including the Macintosh computer. The original Apple IIc was acquired by the Whitney Museum of Art in New York and Time voted it Design of the Year. Soon after Steve Jobs’ departure, Esslinger broke his own contract with Apple and followed Jobs to NeXT.

After leaving Apple, Jobs took a few of its members with him to found NeXT, a computer platform development company that specialized in latest computers. In addition, Jobs helped to start development of the visual effects industry when he funded the spinout of the computer graphics division of George Lucas’s Lucasfilm in 1986. The new company, Pixar, would eventually produce the first fully computer-animated film, Toy Story—an event made possible in part because of Jobs’s financial support.

In 1997, Apple merged with NeXT. Within a few months of the merger, Jobs became CEO of his former company; he revived Apple at the verge of bankruptcy. Beginning in 1997 with the “Think different” advertising campaign, Jobs worked closely with designer Jonathan Ive to develop a line of products that would have larger cultural ramifications. They worked on the iMac, iTunes and iTunes Store, Apple Store, iPod, iPhone, App Store, and the iPad. In 2001, the original Mac OS got replaced with a completely new Mac OS X. NeXT’s NeXTSTEP platform, gave the new OS a modern Unix-based foundation for the first time.

Jobs got diagnosed with a pancreatic neuroendocrine tumor in 2003 and died on October 5, 2011, of respiratory arrest related to the tumor.

Steve Jobs’s world-changing innovations and designs


Apple iMac got introduced in 1998 and its innovative design was directly the result of Jobs’s return to Apple. Apple boasted “the back of our computer looks better than the front of anyone else’s.” Described as “cartoonlike”, the first iMac, clad in Bondi Blue plastic, was unlike any personal computer that came before.

In 1999, Apple introduced the Graphite gray Apple iMac and since has varied the shape, colour and size considerably while maintaining the all-in-one design. The Apple iMac sold for $1,299 at that time. The iMac also featured some technical innovations, such as having USB ports as the only device inputs. This latter change resulted, through the iMac’s success, in the connection being popularised among third-party peripheral makers – as shown by the fact that many early USB peripherals were made of translucent plastic (to match the iMac design).


Apple began work on the first Apple phone in 2005, the first iPhone, released on June 29, 2007. The iPhone created such a sensation that a survey indicated six out of ten Americans were aware of its release. Time Magazine declared it “Invention of the Year” for 2007. The Apple iPhone is a small device with multimedia capabilities and functions as a quad-band touch screen smart phone. in July 2008, Apple released the iPhone 3G with three key features: support for GPS, 3G data and tri-band UMTS/HSDPA.

In June 2009, the iPhone 3GS, whose improvements included voice control, a better camera, and a faster processor. The iPhone 4 is thinner than earlier models, has a five megapixel camera capable of recording video in 720p HD, and adds a secondary front-facing camera for video calls. A major feature of the iPhone 4S, introduced in October 2011, was Siri, a virtual assistant capable of voice recognition.


The MacBook is a brand of portable computer manufactured by Apple Inc. from May 2006 to February 2012, and relaunched in 2015. It replaced the iBook series and 12-inch PowerBook series of notebooks as a part of the Apple-Intel transition from PowerPC. Positioned as the low end of the MacBook family, below the premium ultra-portable MacBook Air and the powerful MacBook Pro, the MacBook was aimed at the consumer and education markets. It was the best-selling Macintosh ever. For five months in 2008, it was the best-selling laptop of any brand in US retail stores. Collectively, the MacBook brand is the “world’s top-selling line of premium laptops.”
