Television: history - the evolution of the first TV

Televisions have become increasingly commonplace over the past few decades. The now inexpensive flat-screen sets are no longer as difficult to acquire as they used to be and for this reason can be spotted in almost every store window. In this tip, we explain how the devices have conquered the market.

This is how the TV evolved

As early as 1843, a physicist described the theoretical principle to transmit certain brightness. But it wasn't until 1883 that Braun, a scientist, invented a tube to split images into signals of a certain brightness and then reassemble them afterwards. This was how images would later be transmitted in radio waves.

1. After Braun's tube was developed, images could be projected onto a glass screen for the first time. For this purpose, electron beams were modified with electromagnetic fields so that they hit a coated glass plate in a certain way.
2. Over time, these inventions were followed by more and more developments that had image transmission as a goal. However, it took quite a while before the television was developed. In between, some physicists succeeded in transmitting different images over a limited distance.
3. Although the Telefunken apparatus reproduced a much higher resolution and thus a better picture, the Telehor, the first television set, was assigned a greater coverage.
4. The further development of the devices was interrupted during the Second World War. Only in the U.S. continued to work on the development of the television.
5. From the 1950s, the television then became a mass medium.
