Television: Evolution, revolution | Manila weather

“TELEVISION (TV) is a gift from God, and God will hold those who use his divine instrument to account to him,” said Philo Taylor Farnsworth, considered by many historians to be the father of modern television. Ironically, the story of the evolution of television is the story of every revolution in humanity’s perception of heavenly possibilities in an increasingly secular, individualistic and globalized society.

On March 10, 1876, when Alexander Graham Bell, of Scottish origin, invented and demonstrated – in his laboratory by a call to his assistant in the next room – the first telephone, one of the most important innovations of the industrial revolution, he postulated the likelihood of a similar gadget that could not only send and receive angelic audio, but share divine visuals as if they were appearances right in front of viewers.

About eight years later, a German, Paul Gottlieb Nipkow, developed a way to transmit images via wires by means of rotating metal discs with perforations, aligned in a spiral. Nipkow’s “electric telescope” had only 18 lines of resolution, but it was in fact the first revolutionary mechanical television.

At the turn of the century, from 1897 to 1907, Boris Lvovich Rosing, a Russian physicist, and Vladimir Kosmich Zworkin, his pupil and assistant who later revolutionized television in the United States, developed the “electric telescope” by replacing the rotating discs. by cathode ray tubes, fused with an automated scanning mechanism.

Two decades later, a 21-year-old American, Farnsworth, proposed a prototype of a fully electronic television system. When a potential investor asked him “when are we going to see dollars on this thing, Farnsworth,” he revolutionized sardonic humor and burned his disbeliever by playing a dollar sign on television.

That same year, John Logie Baird presented the first public demonstration of an electronic television system to a live audience of 50 scientists, and the following year the Scottish engineer – a fellow Bell, oddly enough – did the first revolutionary, transatlantic broadcast from the UK to the US. Baird was also credited with developing the first stereoscopic and color television.

In the 1940s, radio still dominated the airwaves, but by the end of the 1950s, television was dethroning radio as the main source of information and entertainment and dominating the airwaves. In the 1960s, color became widespread on television. Cable television became the thing in the 1970s. VCRs or VCRs were all the rage to accompany television in the 1980s. And high definition disc devices replaced VCRs in the 1990s. In the 21st century, the concept of television escaped traditional televisions and invaded the screens of mobile devices which were the descendants of the Bell telephone. Who knew what would follow in the gradual and exponential evolution of television? What was his next revolution?

The answers were sought at the First World Television Forum on November 21, 1996. At the United Nations General Assembly, delegates declared November 21 World Television Day. It was the year that 18 inch satellite dishes became one of the best-selling devices on the market, revolutionizing the way television was viewed around the world.

In the years that followed, flat panel monitors and HDTVs made CRT screens obsolete, Blu-ray discs outperformed DVDs, and 3D TVs remarkably began to demonstrate angelic audio and divine visuals that Bell could only dream of in his analog lab. .

In 2021, the 25th World Television Day traces the trajectory of television from its roots to the most remote branches of science and technology of tomorrow.
