INTRODUCTION

Am glad to be here once again to make a presentation on television invention based on the research i made, you will learn to always stay glued to your television rather than maybe going to junction to argue on something you did watch live.

How did Television came to be?

Television wave was created to transmit visual images, As early as 1876,Boston civil servant George Carey envisioned complete television system, putting forward drawing for a"selenium camera" that will enable people to see by electricity, Philo Taylor Farnsworth was an American inventor and television pioneer. He made many crucial contributions to the early development of all-electronic television. Wikipedia

The life before and after Television invention

Invention of Television Changed the World
Posted on October 15, 2021 by Foundation for the Future
Television as aTechnology has the biggest impact on how people live in the 21st century. Since its invention in the 1920s, the television has shaped the world in different ways. Now, you’d find at least one TV in every household. In fact, it’s hard to imagine a home without a TV console.

In the following years after television became a home essential, the way we interacted with the device also evolved with technological advances. From home decor to how we speak, televisions drive culture shifts, especially on the home front.

Here’s a look at how television changed the world:

Transformed Home Decor

Before television became a mainstream concept, the interior decor of houses had to be functional. The entertainment area had a radio, piano, or whatever activity the family enjoyed. After families started watching televisions at home, architects considered building homes with a specific living area in mind.

Since the 2010s, TV consoles have also become a staple decor piece in the home. Flat screen television stands become the focal point of living rooms. You’d also find ultra-thin televisions doubling as decorative pieces on the fireplace. You can add even more Abbott decor to the TV stands.

Access to Live Shows

Having access to live shows is another way on how television changed the world. Imagine a world where buying tickets was the only way to experience your favorite live event. That seems hectic and expensive. From the World Cup to other sporting events, televisions allowed fans to enjoy live shows from the comfort of their homes.

Beyond sports, people got access to view defining events like the first moon landing of 1969. This enabled proper documenting of historic events, reaching people from different corners of the world. Now, you don’t have to spend thousands of dollars to catch the Super Bowl games, when you can just turn on your TV.

Improved Social Interaction

TV allowed people with similar interests to connect over their shared love for different programs. Before the internet, watching television shows was a social event. Friends and family members would gather to watch and enjoy their preferred programs. These days, reality TV shows and television series drive massive conversations on the internet.

You’ll find Twitter hashtags containing tweets from people all over the world sharing their thoughts on a certain character or standout scene from the same show or film.

Changed How We Consume Food & Buy Products

Beyond social interaction, TVs influenced how we consumed food and shopped for our homes. Before Cable TV became a global phenomenon, cooking shows only aired during limited time slots. In fact, you’d only catch them during morning specials. Now, independent channels like Food Network broadcast food-related programs 24/7.

This consistent broadcast also birthed the rise of celebrity chefs who popularized food trends. This exposed people to a new world of cuisine featuring dishes from parts of the world they have never visited.

With advertisement, television also forced marketers to tell relatable stories to sell their products. Some companies even created short films to drive sales, creating characters the viewers could relate with. As a viewer, the quality of the advert you see on TV influences your decision to purchase, not necessarily the quality.

Global Consumption of Information

Back in the day, people had limited access to information and news. They had to wait for either radio broadcasts or newspaper reports of happenings all over the world.

Today, the television device has grown to become more than a source of entertainment. With a simple click on a button, you can access live global news from different countries. The device also serves as an educational resource for knowledge seekers. You’ll find a wide range of content teaching social and academic subjects like maths, geography, and science, on dedicated channels.

Gateway to Global Cultures

Before seeing colorful global cultures on your television screen, viewers had a limited worldview. However, through documentaries, you can learn about different cultures from your home. Popular trends across the fashion, film, and food industries also spread all over the world.

People also pick up new languages and vocabulary from the programs they watch. Popular catchphrases became popular thanks to TV characters and celebrities. It’s no longer strange to see people in different communities adopting values they learned from their TV screens.

Digital Entertainment

After many decades, entertainment transformed from a social event to a personal experience. Hence, people now stream their favorite live programs on the internet. Platforms like Netflix changed how we consumed documentaries, movies, and series.

As a result, fewer people watched traditional programs, since the hottest shows moved to the internet. Thankfully, the TV also changed with this evolution.

To cope with the fast-growing digital age, TV companies created the Smart TV and phased out old antenna systems. Smart TVs now offer the best video quality and internet connectivity to popular streaming apps, so viewers don’t have to give up television culture. They also come installed with artificial intelligence software like Alexa and Google Home to help navigate channels with voice commands.

changes, upgrades and modification

Television was not invented by a single inventor. Instead, many people working together and alone over the years contributed to the evolution of the device.

1831
Joseph Henry's and Michael Faraday's work with electromagnetism jumpstarts the era of electronic communication.

1862
Abbe Giovanna Caselli invents his Pantelegraph and becomes the first person to transmit a still image over wires.

1873
Scientist Willoughby Smith experiments with selenium and light, revealing the possibility for inventors to transform images into electronic signals.

1876
Boston civil servant George Carey was thinking about complete television systems and in 1877 he put forward drawings for what he called a selenium camera that would allow people to see by electricity.

Eugen Goldstein coins the term "cathode rays" to describe the light emitted when an electric current was forced through a vacuum tube.

The Late 1870s
Scientists and engineers like Valeria Correa Vaz de Paiva, Louis Figuier, and Constantin Senlecq were suggesting alternative designs for telectroscopes.

1880
Inventors Alexander Graham Bell and Thomas Edison theorize about telephone devices that transmit images as well as sound.

Bell's photophone used light to transmit sound and he wanted to advance his device for image sending.

George Carey builds a rudimentary system with light-sensitive cells.

1881
Sheldon Bidwell experiments with his telephotography that was similar to Bell's photophone.

1884
Paul Nipkow sends images over wires using a rotating metal disk technology calling it the electric telescope with 18 lines of resolution.

1900
At the World's Fair in Paris, the first International Congress of Electricity was held. That is where Russian Constantin Perskyi made the first known use of the word "television."

Soon after 1900, the momentum shifted from ideas and discussions to the physical development of television systems. Two major paths in the development of a television system were pursued by inventors.

Inventors attempted to build mechanical television systems based on Paul Nipkow's rotating disks.
Inventors attempted to build electronic television systems based on the cathode ray tube developed independently in 1907 by English inventor A.A. Campbell-Swinton and Russian scientist Boris Rosing.

1906
Lee de Forest invents the Audion vacuum tube that proves essential to electronics. The Audion was the first tube with the ability to amplify signals.

Boris Rosing combines Nipkow's disk and a cathode ray tube and builds the first working mechanical TV system.

1907
Campbell Swinton and Boris Rosing suggest using cathode ray tubes to transmit images. Independent of each other, they both develop electronic scanning methods of reproducing images.

1923
Vladimir Zworykin patents his iconoscope a TV camera tube based on Campbell Swinton's ideas. The iconoscope, which he called an electric eye, becomes the cornerstone for further television development. Zworkin later develops the kinescope for picture display (aka the receiver).

1924–1925
American Charles Jenkins and John Baird from Scotland each demonstrate the mechanical transmissions of images over wire circuits.

John Baird becomes the first person to transmit moving silhouette images using a mechanical system based on Nipkow's disk.

Charles Jenkin built his Radiovisor and in 1931 and sold it as a kit for consumers to put together.

Vladimir Zworykin patents a color television system.

1926–1930
John Baird operates a television system with 30 lines of resolution system running at five frames per second.

1927
Bell Telephone and the U.S. Department of Commerce conducted the first long-distance use of television that took place between Washington, D.C., and New York City on April 7. Secretary of Commerce Herbert Hoover commented, “Today we have, in a sense, the transmission of sight for the first time in the world’s history. Human genius has now destroyed the impediment of distance in (this) new respect, and in a manner hitherto unknown.”

Philo Farnsworth files for a patent on the first completely electronic television system, which he called the Image Dissector.

1928
The Federal Radio Commission issues the first television station license (W3XK) to Charles Jenkins.

1929
Vladimir Zworykin demonstrates the first practical electronic system for both the transmission and reception of images using his new kinescope tube.

John Baird opens the first TV studio; however, the image quality is poor.

1930
Charles Jenkins broadcasts the first TV commercial.

The BBC begins regular TV transmissions.

1933
Iowa State University (W9XK) starts broadcasting twice-weekly television programs in cooperation with radio station WSUI.

1936
About 200 television sets are in use worldwide.

Coaxial cable—a pure copper or copper-coated wire surrounded by insulation and aluminum covering—is introduced. These cables were and are used to transmit television, telephone, and data signals.

The first experimental coaxial cable lines were laid by AT&T between New York and Philadelphia in 1936. The first regular installation connected Minneapolis and Stevens Point, Wisconsin, in 1941.

The original L1 coaxial cable system could carry 480 telephone conversations or one television program. By the 1970s, L5 systems could carry 132,000 calls or more than 200 television programs.

1937
CBS begins its TV development.

The BBC begins high-definition broadcasts in London.

Brothers and Stanford researchers Russell and Sigurd Varian introduce the Klystron. A Klystron is a high-frequency amplifier for generating microwaves. It is considered the technology that makes UHF-TV possible because it gives the ability to generate the high power required in this spectrum.

1939
Vladimir Zworykin and RCA conduct experimental broadcasts from the Empire State Building.

Television was demonstrated at the New York World's Fair and the San Francisco Golden Gate International Exposition.

RCA's David Sarnoff used his company's exhibit at the 1939 World's Fair as a showcase for the first presidential speech (by Franklin D. Roosevelt) on television and to introduce RCA's new line of television receivers, some of which had to be coupled with a radio if you wanted to hear the sound.

The Dumont company starts making TV sets.

1940
Peter Goldmark invents 343 lines of the resolution color television system.

1941
The FCC releases the NTSC standard for black and white TV.

1943
Vladimir Zworykin develops a better camera tube called the Orthicon. The Orthicon has enough light sensitivity to record outdoor events at night.

1946
Peter Goldmark, working for CBS, demonstrated his color television system to the FCC. His system produced color pictures by having a red-blue-green wheel spin in front of a cathode ray tube.

This mechanical means of producing a color picture was used in 1949 to broadcast medical procedures from Pennsylvania and Atlantic City hospitals. In Atlantic City, viewers could come to the convention center to see broadcasts of operations. Reports from the time noted that the realism of seeing surgery in color caused more than a few viewers to faint.

Although Goldmark's mechanical system was eventually replaced by an electronic system, he is recognized as the first to introduce a broadcasting color television system.

1948
Cable television is introduced in Pennsylvania as a means of bringing television to rural areas.

A patent was granted to Louis W. Parker for a low-cost television receiver.

One million homes in the United States have television sets.

1950
The FCC approves the first color television standard, which is replaced by a second in 1953.

Vladimir Zworykin developed a better camera tube called the Vidicon.

1956
Ampex introduces the first practical videotape system of broadcast quality.

1956
Robert Adler invents the first practical remote control called the Zenith Space Commander. It was preceded by wired remotes and units that failed in sunlight.

1960
The first split-screen broadcast occurs during the debates between presidential candidates Richard M. Nixon and John F. Kennedy.

1962
The All-Channel Receiver Act requires that UHF tuners (channels 14 to 83) be included in all sets.

1962
A joint international collaboration between AT&T, Bell Labs, NASA, British General Post Office, the French National Post, Telegraph, and Telecom Office results in the development and launch of Telstar, the first satellite to carry TV broadcasts. Broadcasts are now internationally relayed.
