TVs that give people a much better viewing experience. But

 

The development of the television was a long process that began in the early 19th century. The first primitive "televisions" were made of a spinning drum with discs on it, each disc hosting an image, which could be seen by everyone in the room. These "perspective" systems first appeared at least a decade before 1855 and had demonstrated the principle used in modern TVs: sending an electrical signal to light up each individual pixel on a screen. But in those days, no matter how primitive the image might have been, it had to be visible from the same angle as the user's eyes. In 1884, Russian inventor Pavel Florensky transmitted signals over a two-mile-long wire to light up a picture of his factory in another room. Florensky also introduced the first system that could be used at home: more than 50 light bulbs sent pictures by wireless telegraphy to flat screens with prisms that direct each of the individual pixels in line with your eyes.

During this time, public interest in radio was huge and people were largely unimpressed by television. Even when it became possible to broadcast live images, a dozen years later, only 6 000 people bought sets. But thanks to the rapid advances in electronics, improvements were constantly made: in 1927, the American inventor Philo T. Farnsworth built the first television that could be mass produced and sold successfully. One year later, Vladimir Zworykin invented a camera tube that could be used in televisions and a year after that an improved cathode ray tube that allowed people to see such things as baseball games live and on their set at home.Television sets became more common and spread around the world. When President Kennedy was assassinated in 1963, millions of people across the world watched it on their new TV sets. Despite that, televisions were still relatively expensive and few people had any idea how much development went into creating them. The first TV sets could not show colour, only black-and-white pictures. Now they are so cheap that you can buy a 32-inch screen with LED TV for less than USD $60.

Looking at the history of innovation and the steady progress in television technology it is difficult to imagine that technology has advanced by leaps and bounds since the early 1990s. We have now gone from black-and-white to full colour and on to 3D. HD technology is also becoming increasingly popular and new features such as Internet access and Wi-Fi are becoming standard features with most TVs these days. It seems logical, then, that we will soon have a new generation of TV sets that willlook very different. But until they're ready, it looks like television is here to stay!TVs (or televisions) were originally just a way for people to see moving images on a screen in their home. But quickly the technology behind them started to develop and become much better. Now there are new technologies like 3D TV and 4Kcould we soon look back at the first televisions in the same way that we now look back at the first mobile phones?The first televisions were mechanical and couldn't be mass produced. The second generation of television sets was electronic, but for each set there had to be a camera filming what was being shown on it. Now, with digital broadcasting, you don't need to have cameras filming for television stations anymore. You can basically record whatever you like and then transmit it digitally across the world.
