Both television and radio have played important roles in history, allowing soldiers to communicate, spreading news almost instantly, providing entertainment for millions, and many other things.
Summary:
-The radio began development in 1870’s
-The first public demonstration of radio was in 1893
-The radio was patented by Guglielmo Marconi in 1896
-The radio is used for war communication, entertainment, and news
-The development of the television began in 1884
-The first working electronic television was completed in 1927
-Television is used for entertainment and news
Radio and television, two communication technologies vital to the everyday lives of billions of people around the world, have each developed over the course of the 19th and 20th centuries. For radio, the technology that came chronologically first, development began in approximately 1870. Television, a much more complicated technology, began development in 1884. However, twenty-four years passed before the conceptualization of the electronic television in 1908. Both television and radio have played important roles in history, allowing soldiers to communicate, spreading news almost instantly, providing entertainment for millions, and many other things.
Radio
After its theorization in 1878 by James Clerk Maxwell, much development went
into radio. Nikola Tesla performed the
first public demonstration of radio in 1893. While at this time primarily two
scientists focused on developing radio technology, Guglielmo Marconi and Nikola
Tesla, Heinrich Hertz (from whose name comes the word for a unit of frequency)
was the first to detect radio waves. Following him, Oliver Lodge, Alexander
Popov, and Edward Brauley developed a practical method for transmitting radio
waves. After Tesla's demonstration, many other scientists soon began development
on radio soon after the demonstration. The first patent awarded for radio went
to Marconi in 1896. One year later he established the first radio station in
the world on the Isle of Wight, England. Six years after this, in 1906, Guglielo
Marconi and Karl Braun were awarded The Nobel Prize in Physics for their contributions
to radio. The next notable development to radio did not come to radio until
much later with the advent of Frequency Modulated (FM) radio, invented by Edwin
Armstrong in 1933.
Radio has seen many uses throughout the 20th century. It was used in many wars throughout the century (including the first and second World Wars) as a method of communication between soldiers, and later in airplanes (both military and non-military) as a method of pilot-to-pilot or pilot-to-ground communication. Radio also has classically been used to distribute many different forms of media to the public, including music, news, and other such content. Television signals are also transmitted using radio, with video as AM, and later sound as FM.
Television
The first major step in the development of the television came in 1884, with
the advent of Paul Nipkow's "Electric Telescope", an electromechanical television
(of sorts). The machine was rather primative, with a resolution of only eighteen
lines. In 1924, another advancement came when John Baird demonstrated an analogue
television in London. Shortly thereafter a company started by Baird broadcasted
the first transatlantic television signal. Though serving well in causing public
interest in television, these early developments in television meant little,
as they dealt mainly with electromechanical television systems, which were quickly
set aside with the arrival of the electronic television. In 1927 Philo Farnsworth
finished the first working electronic television, free from many of the mechanical
moving parts of previous televisions.
Television began to become more and more prevalent after the development of the electronic television. RCA was the first company to begin marketing television sets for use in the home. Stations that broadcasted television signals became commonplace as television sets grew popular. Over the course of the 20th century television has become one of the primary sources for entertainment and information in the lives of millions of people around the world.
These two technologies, radio and television, have revolutionized the lives of billions of people around the world. Radio allows for those in remote areas to stay in communication with the rest of the world; television remains one of the fastest and most global ways for news to reach a great deal of people. Radio was also an important preceding technology for television; without it, television stations would not have a way to easily distribute their content. Television was also a technology that played an important role of the development of computers, a technology that did not come until much later in the 20th century. Together, television and radio have given way to a technological revolution around the world.
Commentary
God is moving in all aspects of life, not simply the strictly religious ones.
If the author wanted to integrate a Biblical worldview they could’ve included
how the invention of the television and radio have been used for God’s
purposes and also how they have detracted from God’s purposes. If one
of the inventors was a Christian the author could’ve commented on the
inventor’s faith.
