When I first started posting schedules for NBC’s experimental station WX2BS in New York City I started with the 1940 simply because it seemed like a natural place to begin. Of course, looking back, I really should have started at the beginning, or at least the beginning of broadcast television. I’m going to be posting schedules from both 1939 and 1940 before hopefully catching up by the time 1941 rolls around.
The medium of television was officially unveiled on Sunday, April 30th, 1939 with the opening of the New York World’s Fair. The New York Times reported on April 23rd that the station would broadcast from 12:30-4:30PM that first day, followed by regular studio presentations on Wednesdays and Fridays from 8-9PM with outdoor pick-ups on Wednesday, Thursday and Friday afternoons [1].
When the outdoor pick-ups started was not made clear, although the article did note that they would be “attempted,” suggesting that they might not have worked as planned. An April 30th article noted that the schedule would likely become monotonous and might not be strictly followed [2]. Thus, there’s no way to know exactly what was shown during the long blocks consisting of “ten-minute transmissions at fifteen-minute intervals” broadcast so salesmen would have something to show potential customers [3].
Here’s a very generic schedule for the first week of broadcast television in the United States:

I suspect the same kind of films shown that first week were seen over the next two years on W2XBS- lots of “obscure” films (some “silent”), tons of “industrial” and “commmercial” shorts, travelogues and old cartoons…as for live remotes, I believe most of them originated from the World’s Fair itself (especially at the RCA exhibition), with “man on the street” interviews, demonstrations, some live “performances”…and studio “filler” at night- “charades”, some drama and comedy, perhaps a cooking demonstration, a fashion show….a fascinating period!
