The original text was this:

''In January 1936, Land gave the first demonstration of Polaroid filters in conjunction with 3D photography at the Waldorf-Astoria Hotel.[34][citation needed] The reaction was enthusiastic, and he followed it up with an installation at the New York Museum of Science.[citation needed] It is unknown what film was run for audiences at this exhibition.

 In 1939, John Norling shot In Tune With Tomorrow, the first commercial 3D film using Polaroid in the US[citation needed].''

Where it says "citation needed" I have looked it up and added it myself:

In January 1936, Land gave the first demonstration of Polaroid filters in conjunction with 3D photography at the Waldorf-Astoria Hotel.[ ] The reaction was enthusiastic, and he followed it up with an installation at the New York Museum of Science.[ ] It is unknown what film was run for audiences at this exhibition.

In 1939, John Norling shot In Tune With Tomorrow, the first commercial 3D film using Polaroid in the US[ ].
