BB-5 7he "SELF-ADJUSTING" Rheostat DIRECT RADIO SELLING by Francis St. Austell (continued from page $8) it. Saloons were popular once, but where are they now?" Correspondence comes from all over the country, from Rhode Island to California, from Maine to New Mexico, and it is a very noteworthy fact that most letters from opponents of the principles of direct selling are on excellent paper and represent a highly educated class, while those from supporters of the direct seller are for the most part, extremely hard to read, are not noted for cleanliness and usually avoid reference to the real subject of debate. The popularity of kfnf is based on its talks, its gospel hymns, religious services and its old-fashioned music. The opponents of direct selling do not necessarily criticize these features, but the loyal followers of kfnf see in an attack on direct selling, a camouflaged attack on the gospel. They want Henry or "Henery" and resent any suggestion of criticism, even of the station presided over by their idol. The owner and operator of kfnf recently broadcast a statement to the effect that those who did not like his station were writing to the Federal Radio Commission, telling that body all about it. He also commented on the fact that these people were sending typewritten letters. The young lady who sorts my mail was discovered once making two piles of letters before opening them. One was a clean, neat pile, the other was quite different. When asked the reason for such a procedure, she remarked "The clean ones object to direct selling, the dirty letters support it." Quite simple, but also very significant. Of course their are some very clean and well written letters favoring direct selling but these are conspicuous in comparison. WHERE DIRECT SELLING IS POPULAR AT A convention in Des Moines, held last year, a speaker attacked the principles of direct selling, without mentioning any stations by name. Mr. Field of kfnf requested that barriers be let down and that the matter be discussed-openly, as he said he was quite aware the remarks referred to him. The way followers of Shenandoah rallied to his support was an eye opener to many. Women, who would ordinarily dread the ordeal of a public appearance, spoke fearlessly and eloquently, facing with real determination a crowded convention hall. Farmers and their wives told of what Henry had done for them, and they left not the slightest doubt as to the popularity of Henry Field among his immediate followers. To his opponents, he represents probably the most unpopular station in the world. Popularity is not the right word. This man, Henry Field, arouses a feeling among his followers that is akin to worship. He is becoming a cult. The reasonable opponents of direct selling do not hesitate to give him credit for all the good things he has done. They fight with him on the points only of direct selling and the methods employed in merchandising. All the foregoing remarks can be applied to other stations, of course, as far as merchandising is concerned; but the magnetic personality of Henry Field makes him stand alone, a national figure, a creation of radio, a leader of hundreds of thousands, almost a prophet, a Moses of the common people. It would seem that the direct selling stations sometimes act as agents for manufacturers and merchants, while certain commodities are bought outright and sold by the station which is in reality a mail order house, with a catalog and also the additional advantage of having a radio station from which to broadcast bargains.
