Major computer events in 1973

The first computer monitor was released on March 1, 1973, as part of the Xerox Alto computer system. The monitor used CRT (cathode ray tube) technology and had a monochrome display.

Martin Cooper

Dr. Martin Cooper made the first handheld cellular phone call to Dr. Joel S. Engel on April 3, 1973.

Robert Metcalfe created Ethernet at the Xerox PARC (Palo Alto Research Center) on May 22, 1973.

New computer products and services introduced in 1973

IBM introduced its 3660 Supermarket System, which used a laser to read grocery prices and UPC (universal product code) barcodes.

The IDMS (Integrated Database Management System) was introduced in 1973.

Interactive laser discs made its debut in 1973.

IBM introduced the 3740 data entry system, using the IBM Diskette, a new storage medium.

IBM released the 3336 disk pack.

IBM introduced the Correcting "Selectric" Typewriter

IBM released the Mag Card II Typewriter with an electronic memory.

IBM introduced the IBM Model 96 single-element typewriter, designed to meet Japanese Katakana alphabet requirements.

Computer and technology-related events in 1973

RFID (radio frequency identification) was patented by Mario Cardullo in January 1973.

The architecture used with the CP/M operating system became the standard for the next eight years until MS-DOS was introduced.

The IBM 3340 disk unit -- known as "Winchester" after IBM's internal project name -- was introduced, an advanced technology that more than doubled the information density on disk surfaces.

Vinton Cerf and Robert Kahn designed TCP (transmission control protocol) in 1973 and later published it with the help of Yogen Dalal and Carl Sunshine in December 1974 in RFC 675.

ARPA (Advanced Research Projects Agency) deployed SATNET, the first international connection.

The first VoIP (Voice over Internet Protocol) call was made in 1973.

The first Landsat satellite was launched on July 23, 1973.

U.S. patent 3,906,166 was filed on October 17, 1973, for a radio telephone system that helped pave the way for what we know today as a cell phone.

Engineers Frank Beck and Bent Stumpe at CERN developed the first transparent touch screen.

On October 19, 1973, Judge Earl R. Larson concluded the ENIAC (Electronic Numerical Integrator and Computer) patent by Eckert and Mauchly was invalid and named Atanasoff the inventor of the first electronic digital computer (ABC).

Dr. Leo Esaki, an IBM Fellow who joined the company in 1960, shares the 1973 Nobel Prize in physics for his 1958 discovery of the phenomenon of electron tunneling. His discovery of the semiconductor junction called the Esaki diode finds wide use in electronics applications. More importantly, his work in semiconductors lays a foundation for further exploration of the electronic transport of solids.
