3D television (3DTV) is a television that conveys depth perception to the viewer by employing techniques such as stereoscopic display, multi-view display, 2D-plus-depth, or any other form of 3D display. The stereoscope was first invented by Sir Charles Wheatstone in 1838. It showed that when two pictures are viewed stereoscopically, they are combined by the brain to produce 3D depth perception. A stereoscope is a device for viewing a stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image.
After then Stereoscopic 3D television was demonstrated for the first time on August 10, 1928, by John Logie Baird in his company’s premises at 133 Long Acre, London. Baird pioneered a variety of 3D television systems using electro-mechanical and cathode-ray tube techniques. The first 3DTV was produced in 1935. And stereoscopic 3D still cameras for personal use had already become fairly common by the Second World War. Many 3D movies were produced for theatrical release in the US during the 1950s just when television started to become popular. People were excited to view the 3D movies, but were put off by their poor quality.

The advent of digital television in the 2000s greatly improved 3D TVs. Although 3D TV sets are quite popular for watching 3D home media. Such as on Blu-ray discs, 3D programming has largely failed to make inroads among the public. Many 3D television channels that started in the early 2010s were shut down by the mid-2010s. As early as 2013, 3D televisions were being seen as a fad.
