In the 1880s a German inventor created simple moving images using a filtered light viewed through a spinning disk, laying the foundations for the modern television. During the 1920s a number of scientists began experimenting with sending still images using radio waves. However, it was in 1928 that General Electric first combined the idea of a device that could show moving images with the technology to wirelessly broadcast them.
During the 30s and 40s the technology was gradually improved upon. In America the first regular broadcasts began in 1939 though it was not until after the Second World War that the television as a standard home appliance began to really take off. After 1945 television sales in America skyrocketed. The first colour broadcast was made in 1954.
