The object of the Red Wing project was "To determine the optimum economic uses of electricity in agriculture and to study the value of electricity in improved living conditions on the farm." Although not the first service to farms in the U.S., it was likely the first built as an experiment specifically for collecting and publishing engineering and economic data.

Prior to the development of circular, corrugated, galvanized steel grain bins, prefabricated, non-corrugated steel bins were used because of cost, portability, rodent resistance and waterproof features, but bin capacity was limited. In the 1920's, corrugated bins, which were larger in size and could support greater loads, were developed and became commercially available. In the 1930's, research programs advanced their use, notably research by F. C. Fenton at Kansas State College of Agriculture and Applied Science and T. E.

On 23 November 1963, this site received the first transpacific transmission of a TV signal from Mojave earth station in California, U.S.A., via the Relay 1 communications satellite. The Ibaraki earth station used a 20m Cassegrain antenna, the first use of this type of antenna for commercial telecommunications. This event demonstrated the capability and impact of satellite communications and helped open a new era of intercontinental live TV programming relayed via satellite.

On 12 September 1958, Jack S. Kilby demonstrated the first working integrated circuit to managers at Texas Instruments. This was the first time electronic components were integrated onto a single substrate. This seminal device consisted of a phase shift oscillator circuit on a tiny bar of germanium measuring 7/16” by 1/16” (11.1 mm by 1.6 mm). Today, integrated circuits are the fundamental building blocks of virtually all electronic equipment.

At the Yokohama Plant of Victor Company of Japan, Limited, a team of engineers headed by Shizuo Takano and Yuma Shiraishi developed VHS (Video Home System) format. They looked ahead to the need for home video tape recorders and embodied their idea in unique inventions. The first model JVC HR-3300 was announced on 9 September 1976. Their basic design with subsequent improvement gained wide customer acceptance.

The HP-35 was the first handheld calculator to perform transcendental functions (such as trigonometric, logarithmic and exponential functions). Most contemporary calculators could only perform the four basic operations – addition, subtraction, multiplication, and division. The HP-35 and subsequent models have replaced the slide rule, used by generations of engineers and scientists.

Dr. Takeshi Takei, the professor at the Tokyo Institute of Technology, discovered that composite oxides containing zinc and iron have distinguished magnetic properties. In 1930, Prof. Takei submitted a paper on his work to Japanese Electro-chemical Society and also presented a paper at 57th General Meeting of American Electrochemical Society in St. Louis. That same year, Prof. Takei applied a patent for his discovery, which was granted in 1932(Japan PAT-98844).
Tokyo Denki Kagaku Kogyo (now TDK Corporation) was founded in 1935 to commercialize this newly invented ferrite cores.

Professor Kenjiro Takayanagi started his research program in television at Hamamatsu Technical College (now Shizuoka University) in 1924. He transmitted an image of the Japanese character イ(i) on a cathode-ray tube on 25 December 1926 and broadcast video over an electronic television system in 1935. His work, patents, articles, and teaching helped lay the foundation for the rise of Japanese television and related industries to global leadership.
The milestone plaque may be viewed at the site of the research at Hamamatsu Technical College (now Shizuoka University).

On 8 March 1979, N.V. Philips' Gloeilampenfabrieken demonstrated for the international press a Compact Disc Audio Player. The demonstration showed that it is possible by using digital optical recording and playback to reproduce audio signals with superb stereo quality. This research at Philips established the technical standard for digital optical recording systems.
This event marked the start of the worldwide development of consumer digital optical recording and reproduction equipment, obtainable by the peoples of the world for a low price.
