Subliminal preaching?

Earlier this week it was announced that Nestle in Germany were using a commercial for their Purina dog-food which was designed to attract dogs to the screen. High pitched sounds during the 24-second advert, some of them outside human hearing range, are designed to appeal to the canine audience. Of course without another quantum leap in bio-technology they will be unable either to select or buy the product once attracted to it! That will doubtless have to await the advent of the i-pooch app, or similar.

Preachers – if others can generate sounds outside the normal hearing range to attract dogs and repel teenage gangs – how about generating some sounds within the human hearing range to attract listeners? Isn’t that what winsome preaching is all about? Just sayin…
