Since the replacement of radio as the most popular mass media in the 1950s, television has played an indispensable role in modern life, and it seems difficult for some people to imagine it without it. Television reflects and shapes cultural values, sometimes criticized for its negative effects on children and young people, and sometimes praised for its ability to create a common experience for all audiences.
Today, as Internet technology and satellite broadcasting change the way people watch television, television entertainment continues to evolve, consolidating its position as one of the most important inventions of the 20th century. However, early televisions were not as thin and light as we see them today, and even appeared directly as a projection. It is reported that the inventors of televisions thought of the concept of television long before the birth of television technology. Early pioneers speculated that if audio waves in electromagnetic waves could be separated from electromagnetic waves, television waves could also be separated to transmit visual images.
Back in 1876, Boston civil servant George Carey conceived a complete television system. In 1926, the British inventor John Roger Baird made the world’s first public display of television systems at Selfridges in London. However, the true mass production of TVs did not officially appear until 1934, and its appearance is mainly wood-based. In addition to displaying black and white images, its screen is quite small.
At the same time, the price is quite expensive, and it is not affordable for ordinary people. Today’s TV is not only thinner and lighter, the picture is clearer, but the price is getting lower and lower. It has already become a civilian product.
