Broadcasting is a way to spread information to a lot of people at once. In the early 1900s, radio broadcasting was invented. Radio uses sound waves to carry information from a transmitter (like a radio tower) to a receiver (like a radio). People would listen to the radio to hear new music, radio programs, and news from all around the world.
Then, in the 1920s, television was invented. Just like radio, television uses sound waves to send information from a transmitter to a receiver. But it also uses something called "pictures," which are moving images sent through the air. People can watch TV to see new movies, TV shows, and news.
Now, broadcasting is used for many different kinds of technologies, like satellite TVs, internet streaming, and more. Broadcasting is everywhere and helps us stay connected to the world!
