Widervia

Widervia was a television set manufactured by Theorysonic. It was the first digital television set ever invented. Introduced at Expo 86, Widervia never made it to mass production due to being too expensive for Theorysonic to manufacture. Being one of the most rarest Theorysonic products ever produced, only five of them were made, Three remained, (one was privately owned and two were displayed in museums) and two were destroyed.
