1939 Digital Computer
John Atanasoff and Clifford Berry of Iowa State College complete the prototype of the first digital computer. It can store data and perform addition and subtractions using binary code. The next generation of the machine will be abandoned before it is completed due to the onset of World War II. -
1947 Polaroid Camera
Dr. Edwin H. Land introduces a new camera that can produce a developed photographic image in sixty seconds. Land will follow in the 1960s with a color model and eventually receive more than 500 patents for his innovations in light and plastics technologies. -
1951 UNIVAC 1
The Eckert and Mauchly Computer Co. of Philadelphia sells the first commercial computer, the UNIVAC 1, to the U.S. Census Bureau. The memory called up data by transmitting sonic pulses through tubes of mercury. An additional 45 UNIVAC 1 machines would eventually be sold. -
1953 Heart-lung Machine
Dr. John H. Gibbon performs the first successful open heart surgery in which the blood is artificially circulated and oxygenated by a heart-lung machine. This new technology, which allows the surgeon to operate on a dry and motionless heart, greatly increases surgical treatment options for heart defects and disease. -
1958 Explorer I
videoThree months after the Soviet Union began the Space Age by launching Sputnik, the U.S. responds by sending the Explorer I satellite into orbit. Explorer I's mission is to detect radiation; it discovers one of the Van Allen radiation belts. -
1960 Laser
videpWorking at Hughes Research Laboratories, physicist Theodore H. Maiman creates the first laser. The core of his laser consists of a man-made ruby -- a material that had been judged unsuitable by other scientists, who rejected crystal cores in favor of various gases. -
1964 Operating System
IBM rolls out the OS/360, the first mass-produced computer operating system. Using the OS/360, all computers in the IBM 360 family could run any software program. Already IBM is a giant in the computer industry, controlling 70% of the market worldwide. -
1965 Minicomputer
Digital Equipment introduces the PDP-8, the world's first computer to use integrated circuit technology. Because of its relatively small size and its low $18,000 price tag, Digital sells several hundred units. -
1976 Super Computer
videoCray Research, Inc. introduces its first supercomputer, the Cray-1, which can perform operations at a rate of 240,000,000 calculations per second. Supercomputers designed by Seymour Cray will continue to dominate the market; the Cray 2, marketed in 1985, will be capable of 1,200,000,000 calculations per second. -
1983 PC
In January "Time" names its 1982 "man" of the year -- the personal computer. PC's have taken the world by storm, dramatically changing the way people communicate. IBM dominates the personal computer market, benefiting both from the production of its own machines as well as "clones" produced by other companies.
