Clarification on 3D television

3D TVs did exist since 1890. This is a link to a wiki that does not allow public editing* that claims that: http://cultureandcommunication.org/deadmedia/index.php/3D_Television


Television started in 1884 when Paul Gottlieb Nipkow made a scanning disk. Only 6 years later, 3D television existed, but was very expensive.
"The first 3-D TV broadcast was on December 19, 1980. It was a 1953 3D feature film, Miss Sadie Thompson, along with a comedy short starring the Three Stooges also from 1953."
