Radios became extremely popular and widespread in the late 1920s and especially the 1930s, in no small part because of soap operas. Writing a decade later, this is what writer James Thurber had to say about the new kind of entertainment that still dominates daytime entertainment:
“A soap opera is a kind of sandwich, whose recipe is simple enough, although it took years to compound. Between thick slices of advertising, spread twelve minutes of dialogue, add predicament, villainy, and female suffering in equal measure, throw in a dash of nobility, sprinkle with tears, season with organ music, cover with a rich announcer sauce, and serve five times a week.”
Thurber was a humorist and writer in the same vein as Mark Twain. He was most famous for his articles and drawings in The New Yorker, but my favorite work from him is The Beast in Me and Other Animals (1948), which features “Soapland,” the best history and commentary on the soap opera that I’ve ever seen. Definitely worth a read!
There is a section in Internet Archives called “Old Time Radio” where you can listen to thousands recordings from the early years of radio. There are tons of good soap operas available here too. Listen and see if you agree with Thurber’s description!
