can avoid being influenced by advertisements. Much as we may pride ourselves on
our good taste, we are no longer free to choose the things we want, for advertising
exerts a subtle influence on us. In their efforts to persuade us to buy this or
that product, advertisers have made a close study of human nature and have
classified all our little weaknesses.
Advertisers discovered years ago that all of
us love to get something for nothing. An advertisement which begins with the
magic word FREE can rarely go wrong. These days, advertisers not only offer
free samples, but free cars, free houses, and free trips round the world as
well. They devise hundreds of competitions which will enable us to win huge
sums of money. Radio and television have made it possible for advertisers to
capture the attention of millions of people in this way.
During a radio programme, a company of
biscuit manufacturers once asked listeners to bake biscuits and send them to
their factory. They offered to pay $10 a pound for the biggest biscuit baked by a listener. The response to this competition was tremendous. Before long,
biscuits of all shapes and sizes began arriving at the factory. One lady
brought in a biscuit on a wheelbarrow. It weighed nearly 500 pounds. A little
later, a man came along with a biscuit which occupied the whole of his car. All
the biscuits that were sent were carefully weighed. The largest was 713 pounds.
It seemed certain that this would win the prize. But just before the
competition closed, a lorry arrived at the factory with a truly colossal
biscuit which weighed 2,400 pounds. It had been baked by a college student who
had used over 1,000 pounds of flour, 800 pounds of sugar, 200 pounds of fat,
and 400 pounds of various other ingredients. It was so heavy that a crane had
to be used to remove it from the lorry. The manufacturers had to pay more money
than they had anticipated, for they bought the biscuit from the student for
$24,000.
