Eighty years ago today, the September 1, 1937, issue of Broadcasting magazine carried this ad for KSTP, St. Paul, Minnesota. The station was boasting its then 25,000 watt signal, and noted that it had received fan mail from 42 states and 8 foreign countries. While the station acknowledged that it did not suggest that it could deliver sales messages to Shanghai, China, it did have a loyal following in the nation’s 7th largest retail market.
