One of the most authoritative voices speaking to us today is，of course，the voice of the advertisers. It shouts at us from the television screen and the radio loudspeakers，waves to us from eVery page of the newspaper，signals to us from the roadside bill-boards all day and flashes messages to us in colored lights all night．
Advertising has been among England’s biggest growth industries since the war．PerhaDs the reason is that advertising saves the manufacturers from having to think about the customer．At the stage of designing and developing a product，there is quite enough to think about without worrying over whether anybody will want to buy it．The designer is busy enough without adding customer-appeal to all his other problems of man．hours and machine telerances and stress fac-tors．so they just go ahead and make the thing and leave it to the advertiser to find eleven wavs of making it appeal to purchasers after they have finished it，by pretending that it offers status，or attracts、love，or signifies manliness．
Other manufacturers find advertising saves them from changing their prodUCt．And manu．facturers hate change．The ideal product is one which goes on unchanged for ever．If，therefore，for one reason or another，some alteration seems calied for—how much better to change the image，the packet or the pitch made by the product，rather than go to all the inconvenience of changing the product itself．
