How TV has evolved over the years
Amongst other things, the television has dramatically changed society and how it was. The first electronic television was invented in 1927. Created by a 21-year-old inventor who went by the name Philo Taylor Farnsworth. Starting when he joined high school, he started to think of a system that could capture moving images. Transform those images into code then move those images along radio waves to different devices.
He was way ahead of any mechanical TV inventor. Philo’s system captured moving images using beams of electrons just like an early camera. The first image he transmitted was a line, following his success his second transmitted image was a dollar sign! This is ironic as an important investor grew tired of waiting and asked Philo “When are going to see some dollars in this thing, Farnsworth?”
By 1934, all television sets all TV’s had been converted into the electronic system as mechanical TV’s no longer had a place. Of course, early TV’s transmitted images in only black and white but the colour television was first theorized in 1904!
The reason mechanical televisions stopped being developed is that electronic televisions where vastly superior. Electronic televisions relied on a technology named a “Cathode Ray Tube” or CRT, as well as two more anodes. The anodes where naturally the positive terminals and the cathode was negative.
The Cathode part of the CRT was a heated filament (like that of a light bulb) enclosed in a glass tube (The T in CRT). The cathode would then release a beam of electronics into the empty space of the tube. (This is a vacuum).
These released electrons of course had a negative charge which would attract to positively charged anodes. As the electrons were released at one end, they were displayed on the television screen at the other end.
So now we know how the TV first came about… but what we are really interested in is the way the television has moulded our society. TV has brought us a lot of good things, on-site breaking news, international broadcasts and live tv! But not every change the television brought is a good one. Studies show that a child in a modern household will witness close to 1 million acts of violence before their 18th birthday. This is due to the endless amount of police dramas, war movies and action films. Similar, some scientists think that TV depicts inaccurate portrayals of sex, beauty and relationships. Broadcasters and program produces argue that they are simply meeting demand and that if they didn’t do such things, people wouldn’t watch. But that debate has gone on for many years and I don’t think we will ever come to a solution.
Television is A pervasive medium, people encounter TV screens everywhere… weather it’s at home or on the street. Generations have grown to know the TV and are now almost reliant on getting information from them. Is it right that a politician’s catchy jingle or on-camera gaffe becomes part of national and even international conversation? The answer can be debated, either way… television has brought a huge change to society and will continue to do so.
