20th Century: 1973

Ethernet developed; this became a popular way of connecting PCs and other computers to share data and devices such as printers. A group of machines connected together in this way is known as a LAN.

The IBM3340 hard disk drive (HDD) that began shipping in November 1973 pioneered new low-cost, low-load, landing read/write heads with lubricated disks and established what became the dominant HDD technology. Al Shugart identified this new “Winchester head” as one of the four most significant mass storage developments.

Global networking becomes a reality as the University College of London (England) and Royal Radar Establishment (Norway) connect to ARPANET. The term Internet is born.

Development of the TCP/IP protocol suite by a group headed by Vinton Cerf and Robert E. Kahn.

The first computer monitor was released as part of the Xerox Alto computer system.

The first VoIP call was made in 1973. Danny Cohen first demonstrated a form of packet voice in 1973 as part of a flight simulator application, which operated across the early ARPANET.

May 1973 – Empire I is the first game in the Empire (PLATO) series. It was most likely the first networked multiplayer game available on an open network allowing more than two players. In this simulation game, up to eight players take control of their respective planets. The screen showed each of the planets and space ships that the players controlled and information about the economy, population, manufacturing, and trade. Space ships could be used to transport goods, attack, and transport military forces.

May 14, 1973: A Saturn V rocket launches Skylab, the first space station.

Judge awards John Vincent Atanasoff as the inventor of the first electronic digital computer on October 19, 1973.

The first broadcast of The Ascent of Man, Moonbase 3, The Wombles, The Young and the Restless, An American Family, Seventeen Moments of Spring, Last of the Summer Wine, and The World at War.

Datalink is founded.

Pioneer is founded.

Founded in 1973, ICCP’s mission is to standardize the certifications given to IS professionals throughout the industry. The mission of the ICCP is to promote the continuous improvement of the Information System profession and professionals through certification, enforcement of a professional code of ethics, standards of conduct, and continuing education.

In 1973 Gary Kildall, a Naval Postgraduate School instructor and consultant to Intel, writes PL/M for the 8008, the first programming language and first compiler specifically for microprocessors. It’s a cross compiler written in ANSI standard Fortran IV so it will run on most computers, including a PDP-10. However, the 8008’s seven-level subroutine call stack is too small to support a self-hosted compiler. Kildall also wrote an 8008 simulator in Fortran IV.

On a summer job in Vancouver, Washington working for TRW, a contractor for the Bonneville Power Administration, in his spare time, Paul Allen adapts the PDP-10 Macro Assembler and DDT debugger to create an 8008 simulator that lets Bill Gates develop code for their 8008-based Traf-O-Data computer built by Paul Gilbert. Allen had previously tried, without success, writing the simulator on the IBM System/360 at Washington State University, where he was studying computer science.
