Television (TV) is a technology that allows the transmission and reception of moving images and sound. It is a form of electronic media that uses a combination of electrical, mechanical, and optical technologies to capture, transmit, and display visual and auditory information.
The invention of television is often attributed to Philo Taylor Farnsworth, an American inventor, and electronic engineer. He developed and demonstrated the first fully electronic television system in 1927, which he called an “image dissector.”
Farnsworth’s invention used cathode ray tubes to capture, transmit, and display images electronically. His system could transmit a simple straight-line image, which he demonstrated to the press in September 1927.
It’s worth noting that a number of inventors, scientists, and engineers had been working on developing television systems for many years before Farnsworth’s invention, including Paul Nipkow, John Logie Baird, and Charles Francis Jenkins.
These inventors developed mechanical television systems that used spinning disks or similar devices to capture, transmit, and display images. But Farnsworth was the first to invent an all-electronic television system.
Farnsworth’s invention laid the foundation for developing modern television systems and the television industry, profoundly impacting society and culture.
Today, television is one of the most popular and widely used forms of electronic media, with billions of people worldwide watching television programs every day.
Types Of Televisions
There are several types of television available in the market:
Cathode Ray Tube (CRT) Televisions
Philo Taylor Farnsworth invented the first type of television. They used a cathode ray tube to produce images and were widely used from the 1930s to the 2000s. However, they have been largely phased out in favor of newer technologies.
Liquid Crystal Display (LCD) Televisions:
These use liquid crystal displays to produce images and are thinner and more energy-efficient than CRT televisions. They became popular in the early 2000s and are now widely used in homes, businesses, and other settings.
Plasma televisions:
These use plasma technology to produce images and are known for their high-quality images and wide viewing angles. They were popular in the early 2000s but have been phased out in favor of LCD and LED televisions.
Light-Emitting Diode (LED) televisions:
These use LED technology to produce images and are known for their energy efficiency and high-quality images. They have become increasingly popular in recent years and are now widely used in homes and businesses.
Organic Light-Emitting Diode (OLED) televisions:
These use OLED technology to produce images and are known for their deep blacks, wide viewing angles, and high contrast ratio. They are considered the most advanced in the market.
Smart Televisions:
These televisions have internet connectivity and other advanced features such as voice control, streaming services, etc.
Applications Of Television
Entertainment: Television is used to watch movies, television shows, and other forms of entertainment.
News And Information: Television is used to watch news programs, documentaries, and other forms of information programming.
Advertising: Television is used to display commercials and other forms of advertising.
Education: Television is used to watch educational programming, including educational shows and documentaries.
Public Service Announcements: Television displays public service announcements, such as announcements about natural disasters and public health emergencies.
Surveillance: Television is used in security systems, such as CCTV cameras, to monitor public and private spaces.
Business: Television is used in many businesses, such as retail stores, hotels, and restaurants, to display information or to entertain customers.
Sports: Television is used to watch live and recorded sports events, such as football, basketball, and baseball games.
