1968 in technology

1968 in technology was a pivotal year marked by foundational breakthroughs across multiple fields. The period saw the conceptual birth of personal computing, significant milestones in space exploration, and the introduction of technologies that would define modern consumer electronics. These advancements collectively set the trajectory for the digital age and reshaped global technological capabilities.

Major technological developments

The year was defined by several landmark events that demonstrated the rapid pace of technological integration into society. The Apollo 8 mission, the first crewed voyage to orbit the Moon, showcased unprecedented capabilities in guidance systems and live television broadcast from deep space. In computing, the public demonstration of Douglas Engelbart's NLS (computer system) at the Fall Joint Computer Conference introduced revolutionary concepts like the computer mouse, hypertext, and graphical user interface. Concurrently, the development of the Intel 4004 microprocessor began at Intel Corporation, laying the groundwork for the microprocessor revolution. In telecommunications, the Carterfone decision by the Federal Communications Commission began breaking the monopoly of the Bell System, fostering future innovation in device interconnectivity.

Computing and information technology

This domain experienced a paradigm shift, moving from large, centralized systems toward interactive and personal computing. Engelbart's "The Mother of All Demos" in San Francisco was a watershed moment, demonstrating real-time collaboration, video conferencing, and word processing. The ARPANET, the precursor to the Internet, had its initial design specifications published by the United States Department of Defense's Advanced Research Projects Agency. In hardware, IBM announced the System/360 Model 85, which featured cache memory, while Robert Noyce and Gordon Moore co-founded Intel. Software saw the development of the Logo (programming language) by Wally Feurzeig and Seymour Papert at the MIT Artificial Intelligence Laboratory, promoting educational computing.

Space exploration and aerospace

Human spaceflight achieved a historic milestone with the NASA Apollo 8 mission. Astronauts Frank Borman, James Lovell, and William Anders became the first humans to leave Earth's gravitational influence, orbit the Moon, and witness an "Earthrise". The mission relied on the powerful Saturn V rocket built by Boeing and North American Aviation. Uncrewed exploration also advanced with the Soviet Union's Zond 5 mission, which performed a lunar flyby and returned biological payloads to Earth. In aviation, the Tupolev Tu-144, developed by the Tupolev design bureau, became the world's first supersonic transport aircraft to fly, preceding the Anglo-French Concorde.

Consumer electronics and telecommunications

The consumer landscape began its transition toward more integrated and portable media. Sony introduced the Trinitron color television system, which set a new standard for picture quality with its single-lens technology. The first successful demonstration of a working LED display was made by Hewlett-Packard, utilizing gallium arsenide phosphide. In audio, the compact cassette, pioneered by Philips, gained significant popularity for music recording and playback. Telecommunications was revolutionized by the aforementioned Carterfone decision, which allowed non-AT&T devices to connect to the telephone network, paving the way for future innovations like the fax machine and modem.

Notable inventions and innovations

Several specific inventions from 1968 had enduring impacts. Douglas Engelbart received a patent for the wooden-shelled computer mouse (originally termed an "X-Y position indicator for a display system"). The CAD and manufacturing industry was transformed with the introduction of UNIX, an operating system created by Ken Thompson and Dennis Ritchie at Bell Labs. In medicine, the first successful human heart transplant in the United States was performed by surgeon Norman Shumway at Stanford University, relying on advanced surgical and support technologies. The field of materials science saw the development of Dynel, a synthetic modacrylic fiber used in wigs and protective clothing.
