The 1939 New York World's Fair
RCA introduced television to the American public at the 1939 World's Fair. Before the fair, they published a brochure for their dealers to explain television. The opening ceremony and events at the fair were televised, and NBC began regularly scheduled broadcasts.
TRK-12s were on display for viewers to see television. These sets used voltage doublers to power the CRTs with about 10 kv to produce a brighter picture than the sets sold to the public. Here is an inventory of spare tubes that RCA brought to the fair to keep its television display working.
In order to convince skeptical visitors that the TV set was not a trick, one set was made with a transparent case so that the internal components could be seen. As part of the exhibit, visitors could see themselves on television, and were give a card documenting the event.

Other manufacturers had television demonstrations, including General Electric, which demonstrated its own sets; Westinghouse, which had sets on display made for them by RCA; and Crosley, which probably demonstrated DuMont sets.
The following is from "Television in the World of Tomorrow", by Iain Baird, ECHOES, Winter, 1997:

Manufacturers other than RCA exhibited their television receivers at the 1939 World's Fair. In 1938, Allen B. DuMont Laboratories, established by the inventor and entrepreneur of the same name, had already offered the first electronic TV sets for sale to the public (prior to the Fair) with their 180 model. Westinghouse Electric and General Electric offered competing production lines of consumer televisions in their own pavillions. These companies also built studios with live cameras for interviews. Even Ford Motor Company got into the act, with television receivers in their executive lounge. Conspicuously missing was Farnsworth Television. Although Philo T. Farnsworth was the first to demonstrate electronic television technology in 1927, his company was not yet manufacturing commercial television receivers. |
