What was the first RADIO soap sponsored by Procter & Gamble, beginning the company's long association with that genre?

...Procter & Gamble's first sponsored network radio soap opera was NBC's "MA PERKINS" (the kindly old lady who always found herself involved with eveyone's problems), in 1933, for Oxydol detergent [produced by Frank & Anne Hummert, who were responsible for dozens of radio soaps for over 20 years]. Their sponsorship became so identified with the program that the title was often announced as "OXYDOL'S OWN MA PERKINS" by the mid-'40s....and it was carried by two networks, NBC and CBS, between 1942 and 1949 (at different times). P&G dropped their exclusive sponsorship in 1956 to concentrate on their TV soaps, but Ma Perkins continued for various advertisers until all radio soaps were forced off CBS' daytime schedule in November 1960.

P&G also sponsored a daily 15 minute show from 1932 through '45 (for Crisco, and later, Oxydol, towards the end of its run; again, on NBC and CBS) that, technically, wasn't a "soap opera"; it was really a daily humorous vignette of a family living in a small Illinois town- Paul Rhymer's legendary "VIC & SADE".

Boy it brings back memories although I wasn't there. Ma Perkins was probably a program my grandmother listened to. Oxydol do they still may dish washing liquid? Tv Fan you sure have knowledge.
