Correction: An Oct. 5 article with the headline "Steve Jobs' Greatest Tech Contributions" incorrectly stated that Steve Jobs was invovled in the creation of Apple Newton Device. Steve Jobs was not a part of Apple Inc. at the time. Neon Tommy regrets the error. 

Steve Jobs, "a visionary and creative genius," has amazed the world with some of the greatest tech innovations of his time. With his unwavering dedication to intuitive personal computing, Jobs introduced some of the greatest contributions to the tech world.  

NeXTCube Computers: 

When Jobs left Apple Inc. in 1985, he took with him his knowledge of personal computers and created Next, Inc. (NeXT). From 1985 till it was purchased by Apple in 1996, Jobs invested his time fully with NeXT. 

During his stint with NeXT Inc., Jobs created several computers--NeXT Computers, NeXT Cube, etc.--running NeXTSTEP, an object-oriented operating system (as opposed to script-oriented systems like DOS). This combination of hardware and object-oriented software reflected Jobs' approach to making personal computers more usable and, in many ways, served as the platform for popular computers today, like the iMac running Apple's OS X. 

iPod: 

The white cords, dancing black silhouettes and the click wheel are synonymous with one of the greatest music devices ever created, the iPod. With it, Jobs not only revolutionized the way people listened to music, but also managed to reshape the music industry by effectively bridging the gap between the physical music media and digital music files for the consumers.  

iPhone: 

In early 2007, Jobs introduced to the world a new device derived from a frustration of the mobile devices at the time. Jobs described it as "A leap-frog product five years ahead of any product out there." After the launch of the iPhone, Apple Computers reinvented itself into a "creative technology company."  

The concept of the iPhone, Jobs once described, came after software engineers showed him the "rubber band" effect seen in the user interface of the iPhone iOS. 

With the advent of the iPhone, the world was introduced to a device marrying the popular iPod device with a smartphone. Within a matter of five years, Apple took over 17 percent of the smartphone market. The iPhone was a large part of Apple Inc. becoming the second most profitable U.S. company with the highest market value of $350 billion in 2011.
