Steve Jobs

January 24, 1984, an emotional Jobs introduced the Macintosh to a wildly enthusiastic audience; Andy Hertzfeld described the scene as "pandemonium." The Macintosh became the first commercially successful small computer with a graphical user interface. The development of the Mac was started by Jef Raskin, and eventually taken over by Jobs.
While Jobs was a persuasive and charismatic director for Apple, some of his employees from that time had described him as an erratic and temperamental manager. An industry-wide sales slump towards the end of 1984 caused a deterioration in Jobs's working relationship with Sculley, and at the end of May 1985 – following an internal power struggle and an announcement of significant layoffs – Sculley relieved Jobs of his duties as head of the Macintosh division.
NeXT Computer
Around the same time, Jobs founded another computer company, NeXT Computer. Like the Apple Lisa, the NeXT workstation
was technologically advanced; however, it was largely dismissed by industry as cost-prohibitive. Among those who could afford it, however, the NeXT workstation garnered a strong following because of its technical strengths, chief among them its object-oriented software development system. Jobs marketed NeXT products to the scientific and academic fields because of the innovative, experimental new technologies it incorporated (such as the Mach kernel, the digital signal processor chip, and the built-in Ethernet port).
The NeXTcube was described by Jobs as an "interpersonal" computer, which he believed was the next step after "personal" computing. That is, if computers could allow people to communicate and collaborate together in an easy way, it would solve many of the problems that "personal" computing had come up against. During a time when e-mail for most people was plain text, Jobs loved to demo the NeXT's e-mail system, NeXTMail, as an example of his "interpersonal" philosophy. NeXTMail was one of the first to support universally visible, clickable embedded graphics and audio within e-mail.
Jobs ran NeXT with an obsession for aesthetic perfection, as evidenced by such things as the NeXTcube's magnesium case. This put considerable strain on NeXT's hardware division, and in 1993, after having sold only 50,000 machines, NeXT transitioned fully to software development with the release of NeXTSTEP/Intel.
Pixar and Disney
In 1986, Jobs bought The Graphics Group (later renamed Pixar) from Lucasfilm's computer graphics division for the price of $10 million, $5 million of which
