First practical of wireless telegraphy systems
"It was Marconi that was awarded the very first wireless telegraphy patent in England in the year 1896, securing his spot in radio's history. A year later, however, Tesla filed for patents for his basic radio in the United States"("History of the Radio")

First North American transcontinental telephone calling
"A long distance call (U.S.) or trunk call in telecommunications is a telephone call made to a place outside of a given local calling area. Usually, long distance calls are charged a higher billing rate than local ones. The term is not necessarily synonymous with other telephone area code being put on calls"("Long-distance calling")

Television
Philo Farnsworth Invents the First All-Electronic Television. 9/7/1927. On September 7, 1927 American inventor Philo T. Farnsworth transmitted an image through the purely electronic means of a device called an "image dissector." This was the first all-electronic television -
First commercial radio-telephone service, U.K.–U.S.
"First U.K.-U.S. radio-telephone service: The first radio-telephone service from the U.K. to the U.S. was established in January of 1927. The phones were initially radio phones, so there were some issues with fading and interference"("The History Of Telecommunication").

First commercial radio-telephone service, U.S.–Japan
"First commercial radio-telephone service, U.S.-Japan: The first radio telephone calls from the U.S. to Japan were first made in 1934. This enabled people to speak across the Pacific Ocean for the first time. Unfortunately, due to the distance, the quality of the calls was not great"(The History Of Telecommunication")

Limited capacity Mobile Telephone Service for automobiles
In June of 1946, the first telephone call was made from an automobile phone. The design had been put together by Southwestern Bell. Due to the cost of installation and the small volume of calls, it wasn't a very extensive mobile network. -
First working transistor (see History of the transistor)
"The principle of a field-effect transistor was proposed by Julius Edgar Lilienfeld in 1925. John Bardeen, Walter Brattain and William Shockley invented the first working transistors at Bell Labs, the point-contact transistor in 1947 and the bipolar junction transistor in 1948"

Semiconductor era begins
"History of semiconductors. The birth history of semiconductors can be traced back to the invention of the rectifier (AC-DC converter) in 1874. Decades later, Bardeen and Brattain at Bell Laboratories in the US invented the point-contact transistor in 1947, and Shockley invented the junction transistor in 1948"("History of semiconductors")

Transatlantic telephone cable
"A transatlantic telecommunications cable is a submarine communications cable connecting one side of the Atlantic Ocean to the other. In the 19th and early 20th centuries each cable was a single wire. After mid-century, coaxial cable came into use, with amplifiers. Late in the century, all used optical fiber, and most now use optical amplifiers"("Transatlantic communications cable")

Metal-oxide-semiconductor field-effect transistor (MOSFET)
"The metal–oxide–semiconductor field-effect transistor (MOSFET) was invented by Mohamed Atalla and Dawon Kahng in 1959. The MOSFET largely superseded both the bipolar transistor and the JFET, and had a profound effect on digital electronic development"("MOSFET")

Commercial telecommunications satellite
"The Communications Satellite Act of 1962 then declares that “The new and expanded telecommunication services are to be made available as promptly as possible and are to be extended to provide global coverage at the earliest practicable date"("Telstar")

Fiber optical telecommunications
"Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared light through an optical fiber. This type of communication can transmit voice, video, and telemetry through local area networks, computer networks, or across long distances"("Fiber-optic communication").

First North American public videophone network
In 1965, the first picturephone service began in trials. These phones were called "Mod I" picturephone sets, and in July of that year, Union Carbide Corporation began trials for the first picturephone network. -
Computer networking
"A computer network is a digital telecommunications network for sharing resources between nodes, which are computing devices that use a common telecommunications technology. Data transmission between nodes is supported over data links consisting of physical cable media, such as twisted pair or fiber-optic cables, or by wireless methods, such as Wi-Fi, microwave transmission, or free-space optical communication"("Computer network")

Discrete cosine transform (DCT) digital media data compression
"A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies. The DCT, first proposed by Nasir Ahmed in 1972. It is used in most digital media, including digital images, digital video, digital audio, digital television, digital radio, and speech coding"("Discrete cosine transform")

Mobile satellite hand-held phones
"A satellite telephone, satellite phone or satphone is a type of mobile phone that connects to other phones or the telephone network by radio through orbiting satellites instead of terrestrial cell sites, as cellphones do. The advantage of a satphone is that its use is not limited to areas covered by cell towers; it can be used in most or all geographic locations on the Earth's surface"("Satellite phone")
