This is a great video. It's 1991 and Steve Jobs (who had not yet returned to Apple) is demonstrating the features of the "NeXT" operating system.

NeXT In 1986, finding himself sidelined by the company he had founded, Jobs sold all but one of his shares in Apple. The single share may have been for symbolic and sentimental reasons or to ensure that he would receive stock reports (as some biography books have stated) and attend shareholder meetings. Around the same time, Jobs founded another computer company, NeXT Computer. Like the Apple Lisa, the NeXT workstation was technologically advanced, but was never able to break into the mainstream mainly owing to its high cost. 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 NeXT Cube 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 a lot 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 NeXT Cube'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. NeXT technology played a large role in catalyzing three unrelated events: The World Wide Web. Tim Berners-Lee developed the original World Wide Web system at CERN on a NeXT workstation. Jean-Marie Hullot's 'SOS Interface' became the basic for Interface Builder which Hullot built for NeXT and which Berners-Lee also used in his project the program 'WorldWideWeb'. NeXT computers were used in the development of the computer game Doom. The return of Apple Computer. Apple's reliance on outdated software and internal mismanagement, particularly its inability to release a major operating system upgrade, had brought it near bankruptcy in the early-to-mid 1990s. Jobs' progressive stance on Unix and open source underpinnings was considered overly ambitious and somewhat backward in the 1980s but ultimately became an expandable solid foundation for an operating system. Apple would later acquire this software and under Jobs' leadership experience a renaissance.
