TVs started in 1884 when Paul Gottlieb Nipkow made a scanning disk. It was able to transmit signals. The cathode ray tube (CRT) is used in his later design but moving images were still not possible, due to the poor sensitivity of the selenium sensors. In 1927, Philo Farnsworth made the world's first working television system which he shown to the press in September 1 1928. In 1936, Kálmán Tihanyi described the principle of plasma television, the first flat panel system.

3D films existed since 1890, but not common until December 2009. There are many techniques to achieve 3D pictures. The most common technique are Anaglyph images, having a 2 separated colors. Another method is to use polarizers, having 2 projectors projecting 2 images, one goes to one side of the polarizer, making it look 3D.
