All about Television
Television turns light and sound into electrical signals, which are sent through the air, cable or internet to a receiver. Early television systems were developed in the 1920s and 1930s.
Today people stream shows and films on the internet, and many screens are connected to online services.
Early televisions were black and white, and colour TV became common in the second half of the 1900s. Today televisions can show very sharp images on flat screens.
Television brings news, education and entertainment into homes around the world. Watching too much TV can be unhealthy, so it is good to balance screen time with other activities.
