The invention of television
Invention of television dates back to 1927 and is due to the endeavors of Philo Farnsworth, John Logie Baird and a Russian, named Vladimir Zworykin. Baird was the first to publicly demonstrate a real TV, as well as other achievements that followed later. Television works by conveying current into a cathode ray tube which forms pictures by scanning them on a luminous plane. The invention changed the development of the Earth, both positively and negatively. The aim of this paper is to give a brief history of the invention of the television, its advantages and disadvantages, and how it generally affects our behavior.
In 1921, Philo Farnsworth suggested an idea that electron beams could somehow scan a photograph horizontally and, thereafter, reproduce an image instantaneously. This breakthrough was really of significance, as it led Philo to the invention of the television in 1927. During the same ages, there appeared a Russian migrant known as Vladimir Zworykin, who apparently had already designed a camera that could focus a photograph via a lens to a tube that was coated with range of photoelectric cells. Then Philo came up with a picture dissector device which made use of an anode finger so as to scan a photograph. A collection of magnetic coiled were used to spray the electrons discharged from the formed electrical picture from left to right and then through line by line onto the opening, from where they turned into electric current. Both the Philo's and Zworykin's devices then conveyed the formed current into a cathode-ray tube, which then formed the picture by scanning it on a luminous plane. This device brought up the idea of television to another level and consequently a significant invention, which would actually change the phase of the Earth ("Television History").
Television revolved the world, drove it to another level, and introduced loads of benefits to the mankind. It acts as actually a good way to pass time in modern society, composed of lonely and busy people. It is also introduced an employment of opportunities for many technicians, actors, newscasters, as well as art designers. TV, if utilized correctly within stipulated limits, forms a vast source of leisure time and knowledge. Moreover, it creates an enormous source of entertainment where people are able to view cricket, soccer, music videos and films. Currently it is installed in most shopping malls to curb robbery. Live TV is connected to a video recording device to show all the activities in the mall ("Who Invented Television").
On the other hand, television has its demerits which, for instance, render a person glued to it for quite a longtime, thus reducing his/her physical activity, which could cause health issues like obesity. It is also classified as a major time waster, especially to people addicted to it. This specifically affects the retired people, housewives, unemployed, and also school kids. In addition, TV has caused heavy dust and thermal pollution by energy plants that operate continuously to meet the ever-increasing demand of power. In terms of health, the television is known to cause eye damages due to the emitted radiations coming off the screens ("Who Invented Television").
A number of populace may perhaps dispute that television is the most horrible innovation that has ever happened, however, the television has caused enormous merits to the people. First and foremost, television has introduced current information to the doorsteps of the people. For instance, one is able to switch on their TV and learn about weather and traffic updates. Also one can access to different channels and watch local and international news and, thus, acquire or rather become informed on current affairs (Wilt, "Television History: The Beginning of a New Medium.").
Secondly, the television has brought education closer to the people. There are numerous daily junior shows that educate them on how to play or count. Subsequently, there are grown-up educational programs like, for instance, the Discovery and National Geographic channels. They allow adults to develop their minds as well as discover something they generally would not know in absence of TV. Education is a great component of our youth and maturity, and it ought to be as expedient as switching on the TV (Ballard, "The Effects of Television.").
Moreover, another extremely significant feature of television is entertainment although many people argue that if television wasn't yet invented, people could read or exercise more. Television entertains through its shows that many people become fans of, for instance, cartoon networks, sporting activities, concerts, and even films.
Television has actually an immense effect on the manner people use their leisure time. It almost certainly affects the younger generation more than the grown-ups, as they spend more time in front of the TV sets. Many critics of TV assert that the television usually consumes a lot of people's free time which they could devote to such activities as reading, family conversations, and also physical exercises ("Social Impact of Television").
From another angle, TV tries to illustrate a globe that actually isn't existent. It regularly promotes the populace to believe that the Earth is more aggressive than it actually is. Via TV, we make fascinating existence of populace and suppose that they are superior to the rest of people ("Social Impact of Television").
TV has an enormous effect on the world politics. During the voting years, campaign news, speeches, and discussions of aspirants are televised nearly daily. Political parties purchase television time so as to air their visions and bring thoughts to the viewers. In this case, television influences the current world politics to a great extent.
Many people ask themselves whether television and movies have an effect on their behavior. Seemingly, many researchers judge that television and movies usually manipulate peoples' behavior. The affected group is the teens, in better and also worse way. Television has much influence on teens because it makes them less active. Watching TV is evidently a passive undertaking, and too much of it causes them to grow unhealthy both physically and mentally. People bring to a close the use of their own imagination during the time they perceive things which, thus, make them misbehave. Psychological laziness eventually proves to be physical laziness, for kids as well as adults would rather observe sports/games on television than go and actually do them. Additionally, they would somewhat assume watching their favorite TV characters rather than going to chat with their own mates or neighbors. That's why living a life of imaginary or rather a fantasy could actually be detrimental to the teens (Boyse, "Television and Children").
Television is also known to make youth be more violent. The more frequently they watch violent actions on TV, the less perceptive they become to such scenes. They eventually perceive violence not to be a wrong deed, which may even lead them to commit cruel activities. This is particularly factual, since they don't constantly comprehend that violent behavior has penalty. Actors that are killed in one TV scene come back in another TV series, which does not correspond to the reality. They fail to remember that murdering somebody is actually permanent (Ballard, "The Effects of Television").
On the other hand, watching television can as well be a good activity. It is capable of broadening our thinking and perception of issues in the world. For instance, watching TV which hosts diverse programs and films can really expose the people to quite different races of people as well as varied cultures. It can actually open peoples' way of thinking, since, for instance, watching programs about handicapped people, reduces prejudice greatly.
Numerous people see TV as a way of reducing stress and pressure and they tend to watch it so as to escape from their prevailing problems for a while. In addition, sometime the television presents programs which educate people on positive methods to resolve their troubles they face. Moreover, TV is seen as a way for people to hide from life, and occasionally, it can assist people in coping with harsh life (Boyse, "Television and Children").
Few inventions have had greater impact all over the world than that of television. The number of US homes has tremendously increased since 1947 to about 98% by the late 1990s. Typical Americans spend about two and half hours to about 5 hours a day watching television. Television has affected most American generations both positively and negatively. It is the parents' choice to regulate what and how much TV to watch, and it is the federal government's choice to regulate what TV stations broadcast in order to sensor sensitive programs that can have negative impact on our kids.
