  1. THE HISTORY OF TELEVISION

  2. THE TELEVISION Television has been an important part of modern culture since the mid-20th century. Its impact on entertainment, news, and communication cannot be overstated. Here is a brief history of television.

  3. STORY The invention of television can be traced back to the early 20th century, with early experiments in transmitting images over radio waves. However, it wasn't until the 1920s and 30s that practical television systems were developed. The first electronic television was created by Philo Farnsworth in 1927, but it wasn't until the 1930s that commercial television broadcasting began in the United States and Europe. During the 1950s and 60s, television became the dominant form of entertainment in many countries. In the 1970s and 80s, cable television and satellite broadcasting brought an explosion of new channels and programming options. The 1990s and 2000s saw the advent of high-definition television (HDTV) and the proliferation of reality TV shows, as well as the growth of online streaming services like Netflix and Hulu, which are now major players in the entertainment industry

  4. FUNCTIONING Television signal reception: The television receives the television signal through the antenna or cable Signal demodulation: the received signal is then demodulated Signal Amplification: The signal is amplified to increase signal strength and improve picture and sound quality. Signal decoding: The signal is decoded, i.e. converted from an analog signal to a digital signal. Signal processing: the signal is processed by the television's microprocessor Image emission: the image is then emitted from the television screen Sound emission: Sound is emitted through the television speakers

  5. today, television continues to evolve and adapt to changing technologies and viewer habits. Smart TVs, which can connect to the internet and offer access to streaming services, have become increasingly popular, and social media platforms like Twitter and Facebook have become important sources of real-time news and commentary.
