Here’s the schedule for NBC’s experimental station W2XBS in New York City for the week starting Sunday, July 9th, 1939, straight from television listings printed in The New York Times. The schedule for Thursday, July 13th is confused due to differences in the day’s daily listings and the weekly listings published earlier on Sunday. I’ve included both for comparison. Otherwise, the weekly listings were either identical to the daily listings or more comprehensive. You can learn all about the theremin, a very unusual electronic instrument that was demonstrated on Tuesday, July 11th by Mary Huntington at Theremin World.
