Perskyi's paper reviewed the existing electromechanical technologies, mentioning the work of Nipkow and others.

The first demonstration of the live transmission of images was by Georges Rignoux and A. A matrix of 64 selenium cells, individually wired to a mechanical commutator, served as an electronic retina.

For many reasons, the storage of television and video programming now occurs on the cloud.

At the end of the first decade of the 2000s, digital television transmissions greatly increased in popularity.

After World War II, an improved form of black-and-white TV broadcasting became popular in the United States and Britain, and television sets became commonplace in homes, businesses, and institutions.

During the 1950s, television was the primary medium for influencing public opinion.

As a 23-year-old German university student, Paul Julius Gottlieb Nipkow proposed and patented the Nipkow disk in 1884.

This was a spinning disk with a spiral pattern of holes in it, so each hole scanned a line of the image.

HDTV may be transmitted in various formats: 1080p, 1080i and 720p.Alternatively television signals are distributed by coaxial cable or optical fiber, satellite systems and, since the 2000s via the Internet.Until the early 2000s, these were transmitted as analog signals, but a transition to digital television is expected to be completed worldwide by the late 2010s.Although he never built a working model of the system, variations of Nipkow's spinning-disk "image rasterizer" became exceedingly common.Constantin Perskyi had coined the word television in a paper read to the International Electricity Congress at the International World Fair in Paris on 24 August 1900.

In the receiver, a type of Kerr cell modulated the light and a series of variously angled mirrors attached to the edge of a rotating disc scanned the modulated beam onto the display screen. The 8x8 pixel resolution in this proof-of-concept demonstration was just sufficient to clearly transmit individual letters of the alphabet.
