All about Television

Television turns light and sound into electrical signals, which are sent through the air, cable or internet to a receiver. The receiver turns the signals back into images and sound. Early television systems were developed in the 1920s and 1930s.

Early TVs were black and white, and colour television became widely available in the 1950s and 1960s. Today people stream shows and films on the internet, and many screens are connected to online services.
