It was not until 1930, he is called a " telescreen sold "at a price of 20 pounds. 1927 The first fully electronic music boxes ("Jukeboxes") used in the USA on the market. German Grammophon on sale due to a license agreement with the Brunswick-Balke-Collender Company. Its first fully electronic turntables.
In 1927, Philo Farnsworth made the first public demonstration of a purely electronic television. [19] During the 1930s, several countries began broadcasting, and after World War II it spread to millions of receivers, eventually worldwide. Ever since then, electronics have been fully present in television devices.
In the 1930s and working independently, American electronic engineer Claude Shannon and Soviet logician Victor Shestakov both showed a one-to-one correspondence between the concepts of Boolean logic and certain electrical circuits, now called logic gates, which are now ubiquitous in digital computers.

The success of transistor radios led to transistors replacing vacuum tubes as the dominant electronic technology in the late 1950s. [28] The transistor radio went on to become the most popular electronic communication device of the 1960s and 1970s. Billions of transistor radios are estimated to have been sold worldwide between the 1950s and ...
The Information Age [a] is a historical period that began in the mid-20th century. It is characterized by a rapid shift from traditional industries, as established during the Industrial Revolution, to an economy centered on information technology. [2]
c. 1930 United States: Vannevar Bush built a partly electronic differential analyzer capable of solving differential equations. c. 1930 United Kingdom: Welsh physicist C. E. Wynn-Williams, at Cambridge, England, used a ring of thyratron tubes to construct a binary digital counter that counted emitted alpha particles. [55]
The first digital electronic computer was developed in the period April 1936 - June 1939, in the IBM Patent Department, Endicott, New York by Arthur Halsey Dickinson. [35] [36] [37] In this computer IBM introduced, a calculating device with a keyboard, processor and electronic output (display). The competitor to IBM was the digital electronic ...
