There are very few inventions like Tv that has a major effect on American society or the whole society in general. before 1947, the number of homes in the US that has Tv could actually be measured in numbers. There were only a few thousand sophisticated homes that hadTelevisions TVs and all. At the time of late 1990, almost 98 percent of the US homes have televisions and each home has at least one TV set and these TVs were always on for an average of almost more than 7 hours per day. An average American actually spent almost 4 to 5 hours watching tv. Others might also watch tv much less than 4 to 5 hours. Actually, this much time of consuming the tv is actually dangerous for both the mental and the physical health of the person who is watching the Tv. It is important to note that this time ids not only the time that is being spent by just sitting in from of the Tv. It is also the time where the people stopped engaging with the communities they actually even stopped reading and going to libraries. The count of people owning a library actually slowed down after the emergence of the powerful invader – the Tv. Going out and socializing also has drastically decreased.


Televisions TVs

Electronic television was first founded and successfully demonstrated in the year of 1927 I the date of September 7 in the place of san Francisco. This system was designed particularly by Philo Taylor Farnsworth, he was just a 21-year-old inventive who has lived in a house with no electricity for almost 14 years. While he was still in high school. Frans actually tried to conceive a system that would actually capture the picture that is moving and also play the sound back. This sound can be got on the radio that would be attached to the TV for the moving screen n ten it may be challenged as such to match with the moving picture. Boris Rosing in Russia had conducted some extreme experiments in transmitting images 16 years before Farnsworth’s first success. Also, he tried to create a system with rotating discs that would capture the moving pictures that were put into the disc. This mechanical system used the scanned images that were placed on the disc and the holes for the rotating disks were arranged quite well in a rotating fashion in a spiral pattern. This has been demonstrated with the help fo John Logie raid who has his home in England and then Charles Francis Jenkins demonstrated this in the united states. This happened earlier in the 1920s. However, the invention of Farnsworth in which the scanned images were projected to the screen with the help of an electron beam is known as the ancestor of modern television. The first image that Farnsworth transmitted on the Tv was just a single line. Soon he tried to incorporate many ideas and he tried in creating a primitive camera with a dollar sign because the investor in the Tv asked him “When are we going to see some dollars in this?”
