For my response, I chose a Bing Crosby Woodbury Soap Show from the mid 1930s. The introduction was a two minute long advertisement in which a host touts the benefits of Woodbury Soap as not just a regular soap, but a beauty product guaranteed to improve women’s skin. The host talks about the product for the first part of the commercial, and spends the second part talking to a man who apparently has two daughters who use the product.
The meat of the program consists of musical numbers, much like the FM radio we know today. However, instead of blocks of songs bookended by commercials, between each song is a brief interlude with a host introducing the song, sometimes engaging in banter with someone else in the studio (or Crosby) . Every so often, a longer interlude will occur, usually about 90 seconds, which is another Woodbury Soap advertisement.
At the very end of the program, the host plugs Woodbury Soap one more time. Based on my relatively limited knowledge of early TV and radio programming, the setup of this program seems relatively standard. A title sponsor provides advertising revenue, and a celebrity provides name recognition. There were relatively few ads during this 25 minute program, and I imagine that someone with knowledge of popular 1934 singers would have enjoyed the amount and variety of music that this show provided.
